Toshiba TCD2565BFG Linear CCD Image Sensor: 5400-Pixel Architecture, Industrial Scanner Integration and Buying Guide

Industrial scanning equipment depends on a carefully balanced relationship between semiconductor sensing architecture, optical resolution, electronic acquisition and mechanical movement. Whether the objective is to reproduce a colour document, inspect fine printed features or acquire controlled optical measurements from a moving sheet, the image sensor must provide information that can be reconstructed accurately under the intended operating conditions. Toshiba TCD2565BFG is a CCD linear image sensor developed around a four-line architecture containing 5,400 sensing elements in each line, with three lines dedicated to red, green and blue acquisition and an additional monochrome line for black-and-white imaging. This combination provides equipment designers with different acquisition possibilities within a defined semiconductor configuration, making the device relevant to document imaging systems and specialized scanner designs where both colour reproduction and intensity-based measurements may be required.

The defining characteristic of Toshiba TCD2565BFG is not simply its 5,400-element resolution. Several linear CCD devices offer similar nominal sensing-element counts, but their physical geometries, colour arrangements, output structures and operating speeds can be substantially different. Toshiba TCD2565BFG uses square photosensitive elements with a 5.25 µm pitch, producing an active sensing-row length of approximately 28.35 mm. Its four-line construction combines closely spaced RGB arrays with an additional black-and-white array located at a different physical separation. This geometry influences how the camera acquires and reconstructs optical information, particularly when the document or inspected material moves relative to the detector. For an original equipment manufacturer, understanding these relationships is essential because the optical assembly, electronic timing and image-processing arrangement must be developed around the actual device rather than a generic description of a colour CCD sensor.

Toshiba identifies photocopiers as the primary application for Toshiba TCD2565BFG and specifies an architecture suitable for approximately 600 dpi acquisition across A4 paper under the intended lens-reduction scanning arrangement. This provides a useful engineering reference for equipment manufacturers developing document imaging hardware or related controlled scanning instruments. However, the device's published application scope should not be interpreted as automatic qualification for every industrial inspection environment. A factory machine examining continuously moving material may require different acquisition speeds, illumination conditions or mechanical protection from those found in a document scanner. The suitability of Toshiba TCD2565BFG for a specialized industrial system should therefore be established through calculations and representative testing rather than inferred solely from its linear CCD construction.

For companies seeking an image sensor supplier, Toshiba TCD2565BFG illustrates why precise semiconductor identification matters during camera development and purchasing. A scanner may be designed specifically around the device's 28.35 mm active sensing length, four-line colour and monochrome geometry, 22-pin package and electrical interface. Replacing it with another detector that also contains 5,400 elements could change the optical field, line registration or PCB requirements. An OEM purchasing department should therefore preserve the manufacturer's exact ordering designation and confirm that the product offered corresponds to the component selected during engineering qualification.

The distinction between the device's colour and monochrome functions also affects acquisition speed. Toshiba's product comparison information identifies a maximum monochrome line rate of approximately 11.6 kHz and a colour line rate of approximately 6.0 kHz. These figures demonstrate that the camera's achievable acquisition rate depends on its selected operating mode. An OEM cannot assume that the faster monochrome rate is available when reconstructing three-channel colour information. The required operating mode should be determined from the actual imaging task, including whether the equipment needs accurate RGB reproduction, monochrome edge measurements or an appropriate combination of supported functions.

Kyptec Automation® provides a dedicated Image Sensor sourcing category covering Toshiba, Hamamatsu and ON Semiconductor technologies. Its published enquiry process requests the manufacturer's name, complete part number and quantity, offering a focused contact point for industrial camera developers, scanner manufacturers and OEM purchasing teams with identified semiconductor requirements. This is particularly useful when a device such as Toshiba TCD2565BFG has been incorporated into an approved scanner design because the required component is defined by more than its broad technology category. Kyptec Automation® also provides international enquiry information, making its sourcing channel relevant to manufacturers seeking specified semiconductor devices from India for equipment production in other markets.

The following guide explains the detailed architecture of Toshiba TCD2565BFG, including its 5,400-element sensing rows, pixel geometry, RGB-to-monochrome array positioning, readout arrangements and electrical integration requirements. It also examines the role of the device in A4 photocopying and controlled scanning, how to evaluate possible industrial applications, and the commercial factors that should be considered when purchasing the component for prototype development or recurring OEM manufacturing. The focus remains on this specific Toshiba device so that equipment designers and buyers can make informed decisions without confusing its characteristics with those of other sensors in the manufacturer's portfolio.

Toshiba TCD2565BFG Four-Line CCD Architecture, Optical Geometry and Electronic Readout

Toshiba TCD2565BFG contains four rows of high-sensitivity PN photodiodes, each providing 5,400 effective sensing elements. Three rows acquire red, green and blue information, while the fourth provides monochrome intensity information. The device uses CCD charge-transfer technology to read the optical signal accumulated during the relevant acquisition period. In a line scanning system, each acquisition represents optical information along a narrow section of the object, and movement between successive acquisitions allows the camera to reconstruct a larger image. This operating principle determines the relationship between the sensor's effective resolution and the mechanical scanning arrangement. The 5,400-element count describes sampling along each sensing row, while the resolution in the direction of document movement depends on line acquisition timing and the corresponding mechanical displacement.

The square photosensitive elements measure 5.25 µm by 5.25 µm and are arranged at a 5.25 µm centre-to-centre pitch. Multiplying that pitch by 5,400 elements produces an approximate active sensing length of 28.35 mm, consistent with Toshiba's published product information. This dimension establishes the physical field onto which the scanning optics must project the relevant portion of the document or inspected object. For an A4 sheet approximately 210 mm wide, the optical arrangement requires a reduction ratio of roughly 7.4 to map the shorter document dimension onto the active sensing row. The actual optical design must also consider scanning margins, working distance, lens characteristics and the semiconductor's mechanical reference geometry. Consequently, the device's nominal 600 dpi capability should be understood as part of an intended optical configuration rather than a guarantee of image resolution independent of the scanner assembly.

For OEM developers evaluating linear CCD image sensors, the active sensing length is an important purchasing and design characteristic. A detector with the same number of elements but a different pitch may require another optical reduction ratio or provide a different field of view when installed behind an existing lens. If the camera PCB and lens assembly have already been developed around Toshiba TCD2565BFG, even a relatively small difference in physical array length can influence the projected image geometry. The camera may no longer capture the intended width, or the optical sampling interval may change enough to affect fine document details. This is one reason the complete manufacturer part number should remain connected to the approved optical design throughout the equipment's manufacturing life.

The spatial arrangement of the four sensing rows is especially significant. Toshiba specifies a separation of approximately 10.5 µm between adjacent colour arrays, corresponding to two element pitches, while the red array and the additional black-and-white array are separated by approximately 31.5 µm, corresponding to six element pitches. These distances determine how far a scanned document must move before the same physical feature reaches another sensing row. In the finished scanner, the processing system must associate measurements taken by different arrays with the correct location on the page. The actual object-space separation depends on the lens reduction ratio, making colour registration a combined optical, mechanical and electronic problem rather than merely a fixed delay entered into software without reference to the camera design.

The relatively close arrangement of the colour arrays is one of the device's distinctive architectural features. In suitable scanner designs, this geometry can influence the amount of movement compensation required between red, green and blue measurements. However, a short physical separation should not be interpreted as automatic colour alignment. The scanner must still maintain appropriate acquisition timing, and any mechanical variation in document transport can create differences between where the individual channels observe a feature. Fine black text, narrow coloured lines and high-contrast printed boundaries are useful during engineering qualification because they can reveal colour fringes caused by inaccurate registration. A camera that produces visually acceptable results on broad colour patches may still exhibit alignment problems when scanning detailed graphics.

The additional monochrome array introduces a different measurement option. Monochrome acquisition provides intensity information without reconstructing conventional RGB colour from three separated rows, which can be useful when the imaging task depends mainly on edges, brightness transitions or geometric features. Toshiba TCD2565BFG also has a higher published maximum line rate in monochrome mode than in colour operation, making the selection of mode relevant to acquisition planning. Nevertheless, the monochrome array is physically separated from the RGB rows, and any attempt to associate monochrome measurements with colour information must account for that geometry. The camera developer should review the manufacturer's specified readout arrangements rather than assume that all four lines operate simultaneously with the same timing or that the higher monochrome rate applies to full-colour acquisition.

Toshiba specifies maximum data rates of 70 MHz for black-and-white operation and 35 MHz for colour operation. These figures describe relevant electronic output capabilities and should not be confused with complete line acquisition rates. The manufacturer also identifies two output channels per line for monochrome operation and one output channel per line in colour mode within its product comparison information. The scanner electronics must acquire the applicable output arrangement correctly and provide processing capacity suitable for the intended scan speed. Where multiple channels are used, differences in analog response may require appropriate calibration to maintain consistent reconstructed intensity. A device that can transfer information at a high electronic rate will not necessarily produce a reliable scan if the supporting controller fails to maintain correct timing or if the optical signal is inadequate.

Sensitivity characteristics provide another important distinction between acquisition modes. Toshiba publishes typical sensitivity values of approximately 14.7 V/(lx·s) for the black-and-white arrangement, 10.2 V/(lx·s) for red, 9.2 V/(lx·s) for green and 4.0 V/(lx·s) for blue under the specified test conditions. The differences demonstrate that raw channel outputs do not necessarily represent equally strong measurements under the same illumination. The spectral distribution of the light source and the reflectance of the scanned material also influence recorded signal. A document scanner should therefore include suitable illumination and channel calibration if consistent colour reproduction is required. Increasing gain in a weaker channel may affect noise as well as signal, so the engineering objective should be to acquire sufficiently useful optical information before relying on electronic correction.

The photodiode architecture is described by Toshiba as high sensitivity with low dark current, which is relevant to reproducing detailed documents containing pale backgrounds, dark printed characters and subtle tonal variations. However, these characteristics must be evaluated within the complete imaging system. The amount of usable signal depends on illumination intensity, integration time, optical transmission and the target's reflectance. Dark current and electronic noise can affect the baseline of the acquired measurement, particularly when the optical signal is relatively weak. A suitable scanner should therefore be tested at the intended operating temperature, scan speed and illumination conditions to establish whether the acquired information supports the required image quality. Manufacturer sensitivity figures provide a valuable technical reference, but they are not a substitute for representative optical testing.

The device uses a two-phase clocking architecture with 5 V input pulses and a typical 10 V supply. The distinction between the drive signals and the principal power supply is important during PCB design because the semiconductor must be operated within the manufacturer's specified electrical conditions. Toshiba also includes an internal clamp circuit, a feature intended to support output signal processing and reduce certain external circuitry requirements. This does not remove the need for correctly designed power regulation, clock generation, output acquisition and grounding. CCD readout can be sensitive to timing errors or electrical disturbances, and the scanner's analog signal chain must be engineered to preserve useful differences between neighbouring sensing elements. The current Toshiba datasheet should be used to establish operating limits and timing sequences rather than adapting a circuit intended for another device on the assumption that all linear CCD sensors use identical interfaces.

Mechanical implementation is similarly device-specific. Toshiba identifies a 22-pin CLCC ceramic package using through-hole mounting, requiring an appropriate PCB footprint and optical positioning arrangement. The detector must be aligned so that the projected image falls accurately on the active sensing lines, while the supporting structure should maintain this geometry throughout normal operation. The package drawing should be used for physical reference locations and assembly clearances, since small differences between semiconductor packages can influence focus and optical coverage. A manufacturer developing recurring scanner production should also control the mounting and calibration process to reduce variation between assembled units. The combination of fine sensing-element pitch and multiple closely spaced arrays makes accurate optical placement particularly important if the finished machine is expected to reproduce small printed details consistently.

A4 Photocopier Integration, Colour Scanning and Precision Industrial Imaging Applications

Toshiba identifies photocopiers as the primary application scope for Toshiba TCD2565BFG. Its four-line architecture and 5,400-element sensing rows support engineering designs requiring controlled acquisition of A4-sized documents at approximately 600 dpi. In such equipment, the optical system projects a narrow portion of the document onto the detector while the document or optical carriage moves through the scanning mechanism. Successive line acquisitions are reconstructed into a complete image, with separate RGB information used where colour reproduction is required and the monochrome arrangement available according to the supported operating mode. This architecture places significant importance on accurate movement, consistent illumination and electronic processing because the semiconductor records the raw optical measurements rather than independently producing a finished document image.

A document scanner must acquire several types of information simultaneously. Fine printed characters require sufficient optical sharpness and accurate reconstruction of narrow boundaries, while photographs and colour graphics require stable tonal response and suitable channel calibration. Pale printed marks can be difficult to reproduce if the illumination or detector response provides insufficient contrast, and high-reflectance regions may produce excessive signal if the acquisition system is not configured correctly. Toshiba TCD2565BFG offers a useful foundation for these applications because its multiple sensing arrangements provide defined colour and monochrome acquisition capabilities. However, the scanner manufacturer must establish the appropriate operating mode and processing conditions from the actual equipment requirements rather than assume that every mode is advantageous for every document.

For buyers researching a colour image sensor for copier or scanner equipment, the distinction between spatial resolution and image quality is essential. A nominal 600 dpi acquisition arrangement provides a defined sampling density, but the useful detail in the completed image depends on how accurately the optical system projects fine text and graphics onto the 5.25 µm sensing elements. Lens distortion, uneven focus and illumination variations can reduce the fidelity of the scan, particularly near the edges of the active field. The camera electronics must preserve the recorded signals without excessive noise or unwanted processing artifacts. A carefully designed scanner should therefore be tested with reference patterns and representative documents covering the entire field rather than judged solely from the nominal number of elements.

The close spacing of the RGB arrays creates a particular engineering requirement during colour scanning. Because the red, green and blue measurements are acquired from physically separated lines, a document moving through the scanning mechanism must advance through predictable distances so that the same printed feature can be represented consistently across channels. Colour registration becomes especially important around fine text and high-contrast edges, where even a small mismatch can create visible fringes. The manufacturer should establish a reconstruction method based on the actual sensing-row geometry and optical reduction, then verify performance at the intended scanning speed. A stable mechanical transport system is necessary because an incorrect movement estimate can affect the relationship between the acquired colour lines. Closely spaced arrays can support practical scanner design, but they do not eliminate the need for accurate synchronization.

Monochrome scanning provides a different operating option for equipment that must reproduce documents in black and white or extract information based primarily on intensity. Toshiba publishes a higher maximum line rate for the monochrome configuration than for colour acquisition, making it relevant to scanners where black-and-white throughput is an important specification. However, a faster sensor acquisition mode does not automatically determine the finished machine's pages-per-minute performance. The mechanical transport, optical exposure and processing system must all support the selected scan speed. The camera should also maintain suitable tonal reproduction so that pale marks, dark text and shaded regions remain distinguishable. A copier that scans rapidly but loses fine printed details may fail its intended image-quality requirements even when the semiconductor operates within its maximum acquisition rate.

The practical relationship between movement speed and acquisition rate can be calculated from the desired sampling interval along the scan direction. At approximately 600 dpi, the longitudinal spacing between acquired lines is about 42.3 µm. A scanner advancing the document at 200 mm per second would require roughly 4,725 line acquisitions per second to preserve that nominal spacing. This rate is within the published maximum values for both operating modes, but the result is only a preliminary calculation. The camera must still receive adequate signal during the available integration period, and the processing electronics must sustain the output without losing information. Mechanical acceleration, document handling and image reconstruction may also influence actual scanning speed. The OEM should therefore use the calculation to guide engineering evaluation rather than interpret it as a guarantee of a particular completed copier throughput.

Industrial document-handling equipment can present related acquisition requirements. Systems used for printed-record digitization, controlled sheet inspection or examination of coloured documents may benefit from high-quality line scanning when the materials can be presented under stable illumination and predictable movement. Toshiba TCD2565BFG can be considered for such designs if its optical geometry and acquisition characteristics match the intended application. Nevertheless, Toshiba's stated application scope is photocopiers, so potential industrial uses require engineering qualification. A machine inspecting rapidly moving packaging material or a large continuous web may place different demands on line rate, environmental robustness and optical coverage. The device should not be described as automatically suitable for every machine vision task simply because it uses a linear CCD architecture.

Manufacturers evaluating a document scanner image sensor should also consider colour calibration throughout the life of the finished equipment. Illumination sources can change their output characteristics over time, while optical contamination or mechanical adjustments can influence the amount of light reaching different parts of the detector. As a result, an image that appears uniform during initial assembly may develop shading or colour variation after prolonged operation. A scanner may require reference measurements and appropriate correction procedures to maintain consistent output. Such correction should refine a fundamentally sound optical acquisition system rather than compensate for severe misalignment or insufficient illumination. The OEM should establish repeatable calibration methods that can be used during manufacturing and, where appropriate, during maintenance.

Fine printed graphics provide another demanding test of the device's acquisition capability. A scanner reproducing technical drawings or documents with closely spaced lines must preserve the boundaries of those features across the full width of the page. The 5,400-element array offers nominal spatial sampling consistent with A4 imaging, but the optical lens must provide appropriate resolution throughout the relevant image field. An error in focus at one edge may reduce the clarity of small features even while the centre of the scan remains sharp. The RGB arrays must also be registered so that coloured lines and annotations appear in their correct positions. Engineering tests should include patterns near the centre and edges of the scan field and should examine the output at the intended acquisition speed.

The additional monochrome line can be useful in certain specialized measurement arrangements where colour is not required for the particular inspection criterion. A controlled scanner might evaluate printed edge locations or intensity transitions using the black-and-white output while preserving the possibility of colour imaging in another supported configuration. However, the engineering team should establish whether such dual capability provides a meaningful benefit. If the equipment uses only monochrome information, the complexity of a four-line colour-capable device may not be justified compared with another approved architecture. Conversely, where a copier or scanner needs both colour and black-and-white operating modes, the combined construction can be a relevant design consideration. The component should be selected because its documented modes satisfy actual product requirements rather than because it offers the greatest number of photodiode arrays.

For OEM manufacturers comparing CCD image sensor suppliers, the commercial sourcing process should follow these technical decisions. Kyptec Automation® offers a dedicated Image Sensor enquiry channel through which buyers can specify Toshiba TCD2565BFG, the required quantity and relevant purchasing information. This provides a focused route for communicating the component after engineering has established its suitability. In established scanner designs, preserving the exact manufacturer part number is important because the optical calibration and electronics may be tied closely to the selected semiconductor. Where a new industrial application is proposed, the purchasing department should avoid committing significant quantities before the complete machine has demonstrated the required image quality under realistic conditions.

Toshiba TCD2565BFG OEM Buying Guide, Scanner Qualification and Worldwide Procurement

Purchasing Toshiba TCD2565BFG for OEM manufacturing requires precise identification of the device and a clear understanding of the equipment in which it will be used. Although Toshiba manufactures several colour and monochrome linear CCD products, the TCD2565BFG configuration has its own sensing-row geometry, electrical requirements, output arrangements and package. The manufacturer designation should therefore be recorded accurately within engineering drawings and the approved bill of materials. A quotation referring generally to a 5,400-element CCD does not provide sufficient assurance that the supplied component will match the design. Similar semiconductor products may use different pixel pitches or array arrangements, leading to changes in optical reduction and registration processing. Even a detector with the same nominal element count should be treated as a separate technical product unless its interchangeability has been established formally.

For buyers seeking a Toshiba image sensor supplier, Kyptec Automation® provides a dedicated Image Sensor product category that includes Toshiba technologies and supports enquiries based on manufacturer, exact part number and quantity. This approach is useful for scanner and photocopier manufacturers because the purchasing request can be tied directly to the semiconductor approved during development. The company also provides worldwide export enquiry information, making the category relevant to domestic and international OEM purchasers. Actual availability, price, lead time, ordering configuration and delivery conditions should be confirmed for the requested quantity, since a live category page does not establish that every manufacturer part is immediately available from stock.

Engineering qualification should precede a recurring purchasing commitment. The OEM should assemble a representative scanner using the intended optical system, illumination, PCB and mechanical transport arrangement, then evaluate whether Toshiba TCD2565BFG produces the required image information. Tests should examine spatial detail across the scanning field, colour-channel alignment, monochrome response, signal stability and the effect of scanning speed. A scanner may reproduce a simple black-and-white chart satisfactorily while showing colour-registration errors or tonal variation on more demanding documents. The qualification program should therefore include representative colour photographs, fine printed text, graphics and low-contrast material. The results should establish the relevant operating settings and acceptance criteria for future production assemblies.

The two-phase 5 V clocking arrangement and typical 10 V supply must be incorporated correctly into the PCB design. The internal clamp circuit can simplify aspects of output conditioning, but the surrounding electronics still need suitable timing control, signal acquisition and stable power. Engineers should consult the current Toshiba documentation for recommended operating conditions and electrical limits rather than adapt another CCD circuit without verification. The selected monochrome or colour mode also influences the output arrangement, requiring the camera controller to process the corresponding signals appropriately. Manufacturing quality procedures should confirm that production boards operate with the intended timing and electronic conditions, since variations in clocking or analog processing can influence scanned image quality.

Mechanical integration should use the device's 22-pin ceramic package information and appropriate manufacturer drawings. Through-hole mounting influences the PCB and assembly process, while the alignment of the active sensing arrays must be maintained relative to the optical image. The scanner's housing should protect the semiconductor and optical components from contamination and mechanical stress during normal operation. A misplaced detector can introduce focus or colour-registration problems even if its electrical operation is correct. Where the OEM produces multiple units, suitable assembly fixtures and calibration procedures can help maintain consistency between scanner assemblies. Accurate mechanical documentation is therefore part of both engineering qualification and dependable component purchasing.

For organizations considering industrial image sensor suppliers, lifecycle and commercial ordering information should be assessed separately from technical suitability. Toshiba provides current product information and an English datasheet dated May 2026 for Toshiba TCD2565BFG, together with more recent environmental documentation, but these publications do not guarantee that any particular quantity is available immediately. Toshiba also notes that representative product numbers on its website may correspond to families with additional commercial ordering characters. An OEM should therefore verify the precise orderable configuration and its current availability before issuing a purchasing commitment. Where the scanner is expected to remain in production for several years, the purchasing team should periodically review relevant manufacturer notices and supply conditions rather than rely solely on historical successful orders.

Production quantity planning should follow the expected number of finished scanner assemblies and actual component consumption. A manufacturer producing a stable photocopier platform may have recurring semiconductor demand, while a specialized document inspection machine may be built only against individual customer orders. The purchasing schedule should account for available inventory, expected lead time and any justified service requirements. Ordering unnecessarily large quantities can create inventory exposure if a camera design changes, while insufficient planning can interrupt manufacturing. The appropriate commercial arrangement depends on the actual component and quotation conditions, so buyers should avoid assuming that volume discounts, reserved inventory or staged deliveries are automatically available. Kyptec Automation® provides a focused channel for submitting defined quantities and discussing the corresponding sourcing requirement.

International purchasing involves additional consideration of shipment destination, import responsibilities and receiving procedures. Kyptec Automation® publishes international export contact information, allowing overseas manufacturers to communicate a requirement for Toshiba TCD2565BFG together with quantity and destination. The commercial quotation should establish relevant pricing, shipment arrangements and applicable terms before the purchase becomes part of a confirmed manufacturing schedule. Depending on the transaction, transportation, duties, taxes and customs handling may influence the total cost of obtaining usable semiconductor inventory. The OEM should also allow for incoming inspection before components are released to production, particularly where the finished equipment is manufactured under controlled quality procedures.

Optical components require suitable handling because contamination or mechanical damage can affect acquired images. The purchasing and receiving teams should confirm that the delivered device corresponds to the approved part number and arrives in appropriate condition for assembly. Relevant identification or traceability information may be retained where required by the company's quality system. During manufacturing, the optical surface should be protected according to Toshiba's applicable guidance, and handling precautions should minimize electrostatic or physical damage. These procedures help maintain consistency between the semiconductor used during development and the components installed into production scanners.

A proposed substitute should never be approved solely because it offers a similar nominal resolution or belongs to the same broad CCD family. Toshiba TCD2565BFG has a specific 5.25 µm pitch, four-line RGB-plus-monochrome architecture and output configuration that may differ from alternative devices. An engineering review should determine whether a proposed replacement affects lens reduction, PCB layout, supply requirements, colour registration or image-processing calibration. Any necessary changes should be tested before purchasing approval. Kyptec Automation® can receive the exact manufacturer requirement for sourcing consideration, while the OEM remains responsible for establishing the technical suitability of the approved component or any formally qualified alternative.

Frequently Asked Questions About Toshiba TCD2565BFG Linear CCD Image Sensor

1. Is Toshiba TCD2565BFG a colour sensor, a monochrome sensor or both?

Toshiba TCD2565BFG incorporates both acquisition types within one four-line CCD architecture. Three sensing lines, each containing 5,400 elements, are associated with red, green and blue information, while a fourth line containing the same number of elements provides monochrome acquisition. This arrangement allows an equipment designer to consider different imaging modes according to the intended task, but those modes have different timing and output characteristics. Toshiba identifies a maximum line rate of approximately 11.6 kHz for black-and-white operation and 6.0 kHz for colour acquisition, meaning that the faster specification should not be applied automatically to full-colour scanning. The camera electronics must be designed to support the selected operating arrangement and its corresponding reconstruction requirements. An OEM should verify the manufacturer's timing documentation and evaluate each required mode within the completed scanner before approving the semiconductor for production purchasing.

2. How many effective pixels does Toshiba TCD2565BFG provide for A4 scanning?

The device has 5,400 effective sensing elements in each of its four lines, providing 5,400 sample positions per row rather than a conventional two-dimensional image made up of 21,600 spatially independent pixels. In a document scanner, these elements sample the projected optical image across the page width, while the second image dimension is acquired through successive line measurements as the document or optical carriage moves. Toshiba associates the configuration with approximately 600 dpi scanning across A4 paper under an appropriate lens-reduction arrangement. However, the manufacturer's nominal resolution should not be interpreted as a guarantee of actual scanner sharpness because the lens, illumination and movement mechanism must preserve sufficient information. OEM developers should evaluate the resolution using suitable test documents and verify detail across the complete scanning field. The number of sensing elements provides an engineering foundation for image acquisition, but the quality of the completed scan depends on the entire optical and electronic system.

3. What is the significance of the 5.25 µm pixel pitch in Toshiba TCD2565BFG?

The 5.25 µm pitch determines the nominal distance between adjacent sensing elements along each linear array and contributes to the device's approximately 28.35 mm active sensing length. This dimension is important when selecting the optical reduction needed to project an A4 document or another inspected field onto the detector. The pitch influences the nominal sampling interval, but the smallest feature that can be reproduced reliably also depends on lens sharpness, illumination and processing. A semiconductor with the same element count but a different pitch may require another optical arrangement, making the exact geometry important during component selection and replacement evaluation. The 5.25 µm sensing-element height is equal to the pitch in this device, but it should not be interpreted as additional independent image resolution in the direction of document movement. OEM qualification should establish actual optical performance using representative targets rather than rely solely on the semiconductor's physical dimensions.

4. Why are the RGB sensing rows in Toshiba TCD2565BFG spaced only 10.5 µm apart?

Toshiba specifies approximately 10.5 µm between adjacent red, green and blue sensing arrays, corresponding to two element pitches. This close spacing influences how far a document moves between the positions at which the separate colour lines acquire information about the same printed feature. The camera must compensate for the physical separation to reconstruct correctly aligned colour information, but shorter spacing does not eliminate the need for timing and movement control. In an A4 scanner, optical reduction changes the relationship between semiconductor separation and document-space movement, so the correct registration method should be developed around the completed optical arrangement. Fine text and sharp coloured boundaries can reveal misalignment through visible colour fringes, making them useful calibration targets. An OEM should verify that the scanner associates corresponding RGB measurements accurately at the intended operating speed rather than assume that the physical closeness of the sensing rows guarantees proper colour reproduction.

5. How does the additional monochrome row differ from the RGB rows in Toshiba TCD2565BFG?

The additional monochrome array records intensity information without the same red, green and blue filtering arrangement used by the separate colour sensing rows. This can be useful in scanner operating modes where the required output depends on brightness and geometric detail rather than conventional colour reconstruction. Toshiba also publishes different sensitivity and acquisition-speed characteristics for the monochrome arrangement, giving the engineering team separate operating considerations. However, the black-and-white array is physically displaced from the RGB rows, with a specified separation of approximately 31.5 µm from the red array, so any attempt to associate monochrome and colour information must account for movement and sensor geometry. The OEM should review the actual supported operating modes before designing a camera around the expectation of using both types of information. The monochrome row is an additional acquisition capability, not evidence that every output can operate simultaneously at the maximum black-and-white line rate.

6. What is the difference between the 11.6 kHz monochrome rate and the 6.0 kHz colour rate?

The two values represent maximum line acquisition characteristics for different supported operating configurations of Toshiba TCD2565BFG. The monochrome arrangement is listed at approximately 11.6 kHz, while colour acquisition is listed at about 6.0 kHz. The distinction is important when determining how quickly the scanner can acquire successive lines of information along the direction of movement. A manufacturer developing a black-and-white document scanner may have different throughput requirements from one producing full-colour images, and the suitable line rate depends on the desired scanning resolution and mechanical speed. However, the finished equipment may also be limited by document transport, illumination or image processing, so the sensor specification alone does not establish a pages-per-minute rating. OEM engineers should calculate the required acquisitions per second and test the corresponding mode under realistic conditions, including sufficient exposure and correct signal capture.

7. Why does Toshiba specify different sensitivities for monochrome, red, green and blue acquisition?

The sensing arrays have different optical responses because the RGB lines employ separate colour filtering and the monochrome line is intended for intensity measurement without the same colour separation. Toshiba publishes typical sensitivities of approximately 14.7 V/(lx·s) for monochrome, 10.2 for red, 9.2 for green and 4.0 for blue under its specified test conditions. These differences matter because a scanner cannot assume that identical illumination produces equal raw output from every channel. The light source's spectral characteristics and the document's reflectance also influence the recorded signal. A colour scanner may therefore require suitable calibration and gain correction to achieve consistent document reproduction. The engineering team should establish sufficient optical signal before relying on extensive electronic amplification, since excessive correction can increase unwanted noise or reduce useful detail. Calibration should be tested with representative documents and maintained according to the equipment's intended operating conditions.

8. Can Toshiba TCD2565BFG be used in a colour photocopier that also offers black-and-white scanning?

The four-line architecture makes Toshiba TCD2565BFG relevant to engineering evaluation for equipment that requires both colour and black-and-white acquisition, and Toshiba identifies photocopiers as its primary application. The three RGB arrays provide colour-related measurements, while the additional monochrome array offers a separate intensity-based option according to the supported operating modes. However, the OEM must implement the relevant electronics, timing and processing arrangements correctly, because colour and monochrome acquisition have different published line rates and output characteristics. A multifunction photocopier also requires suitable optics, mechanical scanning, document handling and software to produce useful images. The presence of both detector arrangements does not independently guarantee a particular machine speed or image quality. Engineering qualification should test the scanner in every intended mode, using text, colour graphics and tonal reference targets before the semiconductor is approved for recurring production.

9. What is the required optical reduction for using Toshiba TCD2565BFG in an A4 scanner?

The device has an approximate active sensing length of 28.35 mm, and the shorter dimension of an A4 sheet is approximately 210 mm. Mapping that document width onto the detector suggests a nominal optical reduction of roughly 7.4 to one before allowing for practical scanning margins, mechanical reference positions and usable image coverage. This calculation provides an initial basis for lens selection, but the completed optical design must also preserve adequate sharpness across the active sensing line. A lens that covers the required image width without resolving fine printed details may not support genuine 600 dpi reproduction. Illumination uniformity, focus and distortion should therefore be evaluated together with magnification. The OEM should use appropriate optical test patterns and verify performance at the centre and edges of the intended field. The detector geometry sets an important design constraint, but the final reduction and lens arrangement should follow the actual scanner construction.

10. Is Toshiba TCD2565BFG suitable for high-speed industrial web inspection?

The device may be evaluated for a particular controlled scanning application, but Toshiba identifies photocopiers as its intended application and does not establish universal suitability for industrial web inspection. A continuously moving film, textile or packaging material may require a substantially different relationship between material speed, inspection width and acquisition rate from that of an A4 document scanner. The OEM should calculate the required line frequency from the process speed and desired longitudinal sampling interval, then compare it with the published 11.6 kHz monochrome or 6.0 kHz colour limit as appropriate. The optical arrangement must also project the required material width onto the relatively compact 28.35 mm detector while preserving sufficient detail. Additional requirements involving illumination, vibration and environmental protection may apply in manufacturing plants. The device should be selected for such an application only after representative testing demonstrates that the complete camera meets the intended inspection criteria.

11. What electrical supplies and timing signals are required for Toshiba TCD2565BFG?

Toshiba identifies a two-phase clocking arrangement using 5 V input pulses and a typical 10 V power supply for Toshiba TCD2565BFG. The camera PCB must provide the required timing and stable electrical operating conditions according to the current manufacturer datasheet. These figures should not be interpreted as interchangeable supplies because the clocking and power functions have different roles within the CCD architecture. The device also contains an internal clamp circuit, but the scanner still requires suitable output acquisition and processing electronics. A PCB developed for another semiconductor may not support this device without changes to timing or mechanical layout, even where the nominal resolution is similar. The engineering team should review recommended operating conditions, absolute maximum limits and relevant readout arrangements before completing the hardware design. Electrical qualification should include representative imaging tests at the operating speeds required by the finished equipment.

12. What is the purpose of the internal clamp circuit in Toshiba TCD2565BFG?

The integrated clamp circuit is part of the device's signal-readout architecture and can reduce certain external signal-conditioning requirements when compared with a design relying entirely on additional circuitry. This integration can be useful to OEM manufacturers developing dedicated scanner electronics, but it does not eliminate the need for accurate clocking, stable supplies, correct signal acquisition or channel calibration. The scanner must still preserve the differences between neighbouring sensing elements that represent fine printed features, and electrical noise can affect that information if the PCB or acquisition chain is inadequately designed. The output should be interpreted according to Toshiba's specified timing and electrical characteristics rather than through assumptions taken from another CCD product. The clamp function should therefore be viewed as one useful integrated feature within a complete acquisition system, not as a substitute for appropriate analog circuit design or image-quality verification.

13. Can Toshiba TCD2565BFG replace Toshiba TCD2564DG in an existing scanner?

Direct replacement should not be assumed merely because both Toshiba devices provide 5,400 sensing elements in their colour arrangements. Toshiba TCD2565BFG uses a four-line RGB-plus-monochrome architecture with a 5.25 µm pitch and approximately 28.35 mm active sensing length, while Toshiba TCD2564DG has a different colour-focused arrangement and a 7 µm pitch producing a longer active sensing row. These differences affect optical magnification, mechanical placement, sensing-row registration and potentially the electronic interface. An existing scanner developed for one device may require significant redesign if the other semiconductor is introduced. The engineering team should compare complete manufacturer datasheets, package information, timing and optical geometry before evaluating any proposed substitution. A replacement should undergo appropriate qualification using representative scanning conditions and image-quality tests. Kyptec Automation® can receive enquiries for the exact originally approved Toshiba part number, helping the buyer avoid an unintended component substitution.

14. What should OEM buyers check before purchasing Toshiba TCD2565BFG in volume?

The purchasing team should first verify that Toshiba TCD2565BFG is the exact semiconductor approved for the equipment and confirm the complete commercially orderable configuration. Toshiba notes that representative product designations displayed in its catalogue may be associated with further ordering characters, making accurate quotation identification important. The buyer should establish the required quantity, destination, expected manufacturing schedule and any relevant handling or documentation requirements. Actual availability, pricing and lead time should be confirmed before the purchase order is finalized rather than inferred from a live manufacturer datasheet. Where a copier or scanner will remain in production over several years, the OEM should also review relevant lifecycle and supply information. Kyptec Automation® provides a dedicated Image Sensor enquiry process based on manufacturer, part number and quantity, giving OEM buyers a focused channel for communicating the precise semiconductor requirement for commercial consideration.

15. Can international OEM manufacturers enquire about Toshiba TCD2565BFG through Kyptec Automation®?

Kyptec Automation® publishes a dedicated Image Sensor offering covering Toshiba, Hamamatsu and ON Semiconductor technologies and provides contact information for worldwide export enquiries. An overseas manufacturer can submit its requirement for Toshiba TCD2565BFG by providing the manufacturer, complete required part number, quantity and destination. This allows the commercial discussion to focus on the specific component rather than a general description such as 5,400-pixel CCD sensor. Actual availability, pricing, ordering conditions and delivery arrangements should be confirmed for the proposed transaction because the presence of an online product category does not establish that every component is held in stock. International buyers may also need to clarify shipping responsibilities, applicable import procedures and receiving requirements before committing to a manufacturing schedule. The benefit of the focused enquiry process is that it provides a practical route for a clearly identified semiconductor sourcing request.

16. Why should scanner and photocopier OEMs consider Kyptec Automation® for Toshiba TCD2565BFG sourcing?

Kyptec Automation® provides a dedicated Image Sensor sourcing category that includes Toshiba semiconductor technologies and accepts enquiries using the make, exact part number and required quantity. This approach is particularly relevant to scanner and photocopier manufacturers because Toshiba TCD2565BFG has a defined four-line sensing architecture, optical geometry, electrical interface and mechanical package that influence the finished equipment. Once a camera or scanner has been developed and qualified around this component, the purchasing department should preserve its manufacturer identity rather than treat another nominally similar detector as interchangeable. Kyptec Automation® offers a focused contact point for communicating that requirement, including enquiries from equipment manufacturers outside India. The category's coverage of other established image sensor manufacturers provides broader sourcing relevance, but those technologies should remain separate from the approved Toshiba component unless engineering formally qualifies an alternative. Commercial availability, pricing and delivery conditions must be confirmed for each requested transaction.

Conclusion: Toshiba TCD2565BFG for Four-Line Colour and Monochrome Scanning and OEM Image Sensor Procurement

Toshiba TCD2565BFG is a four-line CCD linear image sensor designed to provide 5,400 sensing elements per line across three RGB arrays and a separate monochrome array. Its 5.25 µm element pitch, approximately 28.35 mm active sensing length and defined electrical architecture make it relevant to Toshiba's intended A4 photocopier applications and to suitable specialized scanning systems developed under controlled conditions. The combination of colour and monochrome acquisition offers different operating possibilities, but the modes must be evaluated individually because the manufacturer specifies different maximum line rates and output arrangements. A high-quality scanner must coordinate the semiconductor with appropriate optical reduction, stable mechanical movement, accurate colour registration and electronic processing to reproduce useful image information consistently.

The close spacing of the RGB arrays and the separate monochrome sensing line are important technical distinctions within the Toshiba linear CCD portfolio. They influence the acquisition geometry, the timing required to associate measurements with the same document location and the type of signal processing needed by the finished equipment. The difference between the 11.6 kHz monochrome and 6.0 kHz colour line-rate specifications also demonstrates why the chosen operating mode must correspond to the actual scanning requirement. Nominal 600 dpi capability is valuable only when the lens, illumination and scanner mechanism support genuine image detail, while electronic calibration should refine accurate optical measurements rather than compensate for fundamental design weaknesses.

Kyptec Automation® provides a dedicated image sensor supplier in India enquiry channel covering Toshiba CCD technologies for OEM requirements. Scanner manufacturers, industrial equipment developers and international buyers can submit their requirement for Toshiba TCD2565BFG together with the complete part number, quantity and delivery destination for sourcing consideration. Its focused Image Sensor category enables manufacturer-specific communication while keeping the commercial discussion connected to the semiconductor that has been approved for the equipment. Actual availability, pricing and delivery terms should be established during the enquiry process rather than assumed from general product information.

A dependable Toshiba TCD2565BFG purchasing decision combines accurate interpretation of its four-line CCD construction with suitable optical design, correct electrical integration, meaningful qualification testing and precise component identification. By maintaining that connection between engineering and procurement, OEM manufacturers can make better-informed decisions about colour and monochrome scanner development and support consistent production of equipment that depends on this specialized image sensing architecture.
