2. CCD Adjustment Data all items under COPIER>ADJUST>CCD
COPIER/ADJUST>ADJ-XY>ADJ-Y (CCD read start position adjustment)
It is used to adjust the parameter used determining the read start position in main scanning direction.
Range: 0 to 400 (A change by ‘12’ results in a shift of 1 mm.)

Execute the mode after replacing the CCD unit, scanning lamp, reader controller PCB, or standard white plate.
COPIER>ADJUST>CCD>PPR (density data of standard white paper)
COPIER>ADJUST>CCD>PLT (density data of standard white plate)
COPIER>AJDUST>CCD>GAIN-E/O (gain adjustment input of CCD
output)
COPIER>ADJUST>CCD>OFST-E/O (offset adjustment input of CCD
output)
COPIER>ADJUST>CCD>SH_RATIO (white level ratio data of standard white plate and standard white paper during shading correction)
