I want to use a linear CCD-sensor for my project and I bought this old tablet scanner from 2004 - Genius ColorPage-HR7XE. I disassembled all the parts and took out the PCB with CCD-scanner. But I didn't want to unsolder it because it would be great if I could reassemble and use the scanner again. So, I found the corresponding service manual, but it's not quite readable. Also, I asked AI about this but he insisted on checking not existing component that's why I came here to ask.

CCD PCB schematic from the service manual

Below is page 32 from the Genius HR-7Xe Service Manual, redrawn. The manual has poor resolution bitmap images of schematics, unfortunately.

    \$\begingroup\$ If you have access to a microscope, the part number and/or manufacturer are usually etched into the top metallization layer (on the sensor substrate, usually in a corner) \$\endgroup\$ Commented Oct 31 at 3:18

  • \$\begingroup\$ Also, I found out that this schematic that moderators have found is not quite it - better check the service manual itself and its schematic because it has many differences in pinouts (not CCD), IDs of components (resistors, capacitors etc.). You can see how some components names are different on PCB, for example, capacitors on the collectors of transistors have different numbers. \$\endgroup\$ Commented Oct 31 at 19:19
  • \$\begingroup\$ @Стебан - Hi, (a) FYI you're mistaken that moderators or "moders" (assuming you mean diamond moderators, like me) edited your question. Another site member with edit privileges did that. (b) As I understand it, the original schematic in the question was such low resolution that it was unusable, so they kindly tried to help by adding a more readable schematic. \$\endgroup\$ Commented Oct 31 at 19:33

The part number shown in the schematics seems to be "UPD8872", referring to "µPD8872", which is a 10800 pixel, 3 color CCD linear image sensor released in 2001.

Here's the datasheet, and at least the pinout matches the one on the schematic.
