Image Processing
Overview
The functions of image processing system’s PCB are described below.

Main controller PCB | Shading correction (executed per each job),
CCD PCB | CCD drive, analog image process, A/D conversion, A/D conversion, backup of the service mode about the reader and ADF

The machine uses the main controller PCB to process images for every single image line. Specific functions are as follows.
a. Main controller PCB
Shading correction
Color offset correction in sub scanning
b. CCD PCB (inside CCD unit)
CCD drive
CCD output gain correction, offset correction
