Be sure to generate the latest P-PRINT printout before replacing the reader
controller PCB.
- If you are initializing the RAM on the reader controller without replacing
the PCB
Using the SST, upload the backup data of R-CON; initialize the RAM, and
then download the data, thus eliminating the need for the following.
1) Using the SST, download the latest system software (R-CON).
2) Make the following selections in the service mode: COPIER > FUNC-
TION > CLEAR > R-CON. Then, press the OK key to execute RAM in-
itialization. Thereafter, turn off and then back on the main power.
3) Enter the appropriate settings for the following items in the service mode:
a. setting indicated on the service label (found behind the reader unit front
cover)
a-1. image read start position adjustment (X direction; in fixed reading
mode)
COPIER>ADJUST>ADJ-XY>ADJ-X
a-2 image read start position adjustment (Y direction; in fixed reading
mode)
COPIER>ADJUST>ADJ-XY>ADJ-Y
a-3 shading position adjustment (in fixed reading mode)
COPIER>ADJUST>ADJ-XY>ADJ-S
a-4 feeder mode main scanning position adjustment
COPIER>ADJUST>ADJ-XY>ADJ-Y-DF
a-5 ADF stream reading CCD reading position
COPIER>ADJUST>ADJ-XY>STRD-POS
a-6 density manipulating value adjustment
COPIER>ADJUST>CCD>DFCH-G2
COPIER>ADJUST>CCD>DFCH-G10
(After inputs it, execute COPIER>FUNCTION>DF-LNR)
The machine retains ADF-related service data in the RAM of its reader con-
troller.
ADF adjustment is necessary whenever you have replaced the reader con-
troller or initialized the RAM.
b. original stop position adjustment (X direction) (stream reading)
FEEDER>ADJSUT>DOCST
c. original feed speed (magnification) adjustment
FEEDER>ADUST>LA-SPEED
4) Make adjustments using the following service mode items:
a. ADF sensor sensitivity adjustment
FEEDER>FUNCTION>SENS-INT
b. tray width adjustment
FEEDER>FUNCTION>TRY-A4
FEEDER>FUNCTION>TRY-A5R
FEEDER>FUNCTION>TRY-LTR
FEEDER>FUNCTION>TRY-LTRR
c. white plate data adjustment
COPIER>FUNCTION>CCD>CCD-ADJ
d. ADF white level adjustment
COPIER>FUNCTION>CCD>DF-WLVL1
COPIER>FUNCTION>CCD>DF-WLVL2
Be sure to perform white plate data adjustment before performing ADF
white level adjustment.
After having made the foregoing adjustments, put the P-PRINT printout in
the service book case, replacing the previous P-PRINT printout.
