For this project 2 used scanners sold as defective were bought. 1x V300 and 1x V370.

The V300 still worked but lacked some accesories and is used as a reference. 

The v370 had a broken usb port and even after replacement it still did not work so the s93c46 eeprom was dumped and transferred to the working V300 essentially transforming it into a V370 which advertises a higher resolution of 4800dpi.

The CCD assembly was kept intact for now in order to capture data from a working unit for analysis in the next log.

The main processor interfacing the CCD is actually not the one next to the USB port but a R7700200A0 on the underside with a big ram connected to it. The R720G000A0 seems to be only a HS USB interface for communication.

The Sensor used in these scanners seems to be the 12 line (RGB x2x2 Main+Sub line) ILX561K CCD with 122,400 total pixels.
Because the lines are next to each other there is an offset of several pixels between them that needs to be corrected after capturing a few lines.

After startup these scanners home the main sensor axis and the light in the lid and if the homing fails or a white strip in the home position for calibration is not seen by the sensor the scanner enters a fault state.
This means that if i were to just repackage this scanner into a different project the lid must be emulated or kept in some way to generate the homing pulse. It will not work without the lid attached or with the glass containing the calibration strip removed.

The sensor is split into 12 lines. Each color has 2 groups of 2 lines each for 4 lines per color. It is likely comparable to the 6 line ILX585K where a public datasheet is available. The pixel pitch there is (likely) 4µm with 48µm? between main lines and 8µm? between sub lines for an effective 1µm pixel pitch of the staggered pixels in this sensor.

Because the ILX561 sensor has 2 main lines per color the distance between colors is likely double the distance of the ILX585K. This will be important to know later during image processing.
