Component
Supplies charge to 1) the four image transfer rollers that pull
the toner images from the four from the four drums (Y, M,
C, K), and 2) to the paper transfer roller that pulls the image
off the ITB onto paper.
Supplies the dc/ac charges for paper separation.
Controls the motors that drive the OPC drums and ITB.
Performs: 1) Image processing control, 2) GW controller
interface, 3) peripheral timing control.
Processes data from the Y, M, C, K, potential sensors.
Sorts and routes signals to electrical components.
One of two ID control boards at the base of the Cyan STC.
The CPU reads the board to confirm that the correct STC is
inserted into the correct bin.
One of two ID control boards at the base of the Magenta
STC. The CPU reads the board to confirm that the correct
STC is inserted into the correct bin.
One of two ID control boards at the base of the Black STC.
The CPU reads the board to confirm that the correct STC is
inserted into the correct bin.
One of two ID control boards at the base of the Yellow STC.
The CPU reads the board to confirm that the correct STC is
inserted into the correct bin.
Contains the CCD. Converts CCD analog signals to digital
signals.
Controls all the sensors in the scanner unit and controls the
carriage drive stepping motors.
Converts the dc power input to a stable, high frequency ac
output to the exposure lamp.
