1. Adjustment related to the reader unit
1)Using SST, download the latest system software (R-CON).
2)Select the following service mode; COPIER > FUNCTION > CLEAR >
R-CON,
hold down OK, and then execute RAM clear. After that, turn off/on the
main power switch.
3)Enter the values of the following items in service mode.
a. Value on the service label (inside of the reader left cover)
a-1.Adjusting the CCD reading position (in fixed reading)
COPIER>ADJUST>ADJ-XY>ADJ-X
a-2.Adjusting the position in main scanning direction (in fixed reading)
COPIER>ADJUST>ADJ-XY>ADJ-Y
a-3.Adjusting the shading position (in fixed reading)
COPIER>ADJUST>ADJ-XY>ADJ-S
a-4.Value of MTF in main scanning direction
COPIER>ADJUST>CCD>MTF3-M1/M2/M3/M4/M5/M6/M7/M8/
M9
After that, finalize the setting in the following mode.
COPIER>ADJUST>CCD>CCD-CHNG
a-5.Value of copyboard sub scanning magnification adjustment
COPIER>ADJUST>ADJ-XY>ADJ-X-MAG
a-6.Value of Pascal offset (black) adjustment
COPIER>ADJUST>PASCAL>OFST-P-K
a-7.Value of 100% color displacement correction
COPIER>ADJUST>CCD>100-RG/100-GB
a-8.Value of 50% color displacement correction
COPIER>ADJUST>CCD>50-RG/50-GB
b.Entering the data of the standard white plate
COPIER>ADJUST>CCD>W-PLT-X/Y/Z
F-5-44
2. Adjustment related to ADF
1)Enter the value of the output P-PRINT in the following item in service
mode.
a. Adjusting the position in main scanning direction (in stream reading)
COPIER>ADJUST>ADJ-XY>ADJ-Y-DF
b. Adjusting the trailing edge registration
FEEDER>ADJUST>DOCST
c. Adjusting magnification
FEEDER>ADJUST>LA-SPEED
2)Execute adjustment using the following items.
a. Adjusting the tray width
FEEDER>FUNCTION>TRY-A4
FEEDER>FUNCTION>TRY-A5R
FEEDER>FUNCTION>TRY-LTR
FEEDER>FUNCTION>TRY-LTRR
b. Adjusting the CCD reading position (in stream reading)
COPIER>FUNCTION>INSTALL>STRD-POS
c. Adjusting the white level
COPIER>FUNCTION>CCD>DF-WLVL1(black and white)
COPIER>FUNCTION>CCD>DF-WLVL2(black and white)
COPIER>FUNCTION>CCD>DF-WLVL3(color)
COPIER>FUNCTION>CCD>DF-WLVL4(color)
After completing the above adjustments, keep the output P-PRINT [1] in the
service book case and dispose the old P-PRINT
F-5-45
Be sure to output P-PRINT in service mode before replacement.
COPIER>FUNCTION>MISC-P>P-PRINT
Be sure to output the latest P-PRINT before replacing the reader controller
PCB.
-In the case of clearing RAM for the reader controller without replacing the
