<if you are initializing the RAM of the reader controller without replacing
the PCB>
- Using the SST, upload the reader controller backup data; after initializing
the RAM, download the data, thus eliminating the need for the following
adjustment.
1. Reader Unit-Related Adjustment
1) Using the SST, download the latest system software (R-CON).
2) Make the following selections in service mode:
COPIER>FUNCTION>CLEAR>R-CON; then, press the OK key to
initialize the RAM. Thereafter, turn off and then on the main power.
3) Enter the appropriate values using the following service mode items:
a. standard white plate white level data
COPIER>ADJUST>CCD>W-PLT-X,Y,Z
b. offset value against color displacement for copyboard glass (copyboard
cover)
COPIER>ADJUST>CCD>BOOK-RG
c. offset value against color displacement for copyboard glass (ADF)
COPIER>ADJUST>CCD>DF-RG
F-14-7
d. service label (behind reader unit left cover) values
d-1. CIS read position adjustment (fixed reading)
COPIER>ADJUST>ADJ-XY>ADJ-X
d-2. main scanning direction position adjustment (fixed reading)
COPIER>ADJUST>ADJ-XY>ADJ-Y
d-3. shading position adjustment (fixed reading)
COPIER>ADJUST>ADJ-XY>ADJ-S
d-4. sub scanning direction color displacement correction
COPIER>ADJUST>CCD>CCDU-RG
d-5. main/sub scanning direction MTF value
COPIER>ADJUST>CCD>MTF-MG,SG
d-6. auto gradation correction target value
COPIER>ADJUST>PASCAL>OFST-P-Y,M,C,K
If the value of the following was not 0 before the replacement of the
reader controller PCB: COPIER>OPTION>BODY>CCD-LUT.
Set a value other than '0' once again, and make the following adjustments
using the D-10 Chart.
COPIER>FUNCTION>CCD>LUT-ADJ2
2. ADF-Related Adjustment
The machine keeps ADF-related service mode data in the RAM of the
reader controller; as such, you will have to make the appropriate
adjustments if you have replaced the reader controller or initialized the
RAM.
1) Enter the values indicated in the P-PRINT printout you have previously
generated for the following:
a. main scanning direction position adjustment (stream reading)
COPIER>ADJSUT>ADJ-XY>ADJ-Y-DF
b. original stop position adjustment
FEEDER>ADJSUT>DOCST
c. original feed speed (magnification) adjustment
FEEDER>ADUST>LA-SPEED
2) Make adjustments using the following items:
a. tray width adjustment
FEEDER>FUNCTION>TRY-A4
FEEDER>FUNCTION>TRY-A5R
FEEDER>FUNCTION>TRY-LTR
FEEDER>FUNCTION>TRY-LTRR
b. CIS read position adjustment (stream reading)
COPIER>FUNCTION>INSTALL>STRD-POS
c. white level adjustment
COPIER>FUNCTION>CCD>DF-WLVL1
COPIER>FUNCTION>CCD>DF-WLVL2
When you have finished the foregoing adjustments, put the P-PRINT print-
out [1] you have previously generated in the service book cassette to replace
the old P-PRINT printout.
