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 service mode:
COPIER> FUNCTION> CLEAR> R-CON. Then,
press the OK key to execute RAM initialization.
Thereafter, turn off and then back on the main
power.
3) Enter the appropriate settings for the following
items in service mode:
a. settings 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

a-4 feeder mode main scanning position adjustment
COPIER>ADJUST>ADJ-XY>ADJ-Y-DF
a-5 ADF stream reading CCD reading position

The machine retains ADF-related service data in the
RAM of its reader controller,
thus necessitating ADF adjustment whenever you
have replaced the reader controller or initialized the
RAM.
b. original stop position adjustment
FEEDER>ADJSUT>DOCST
c. original feed speed (magnification) adjustment
FEEDER>ADUST>LA-SPEED
4) Make adjustments using the following service

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

d. ADF white level adjustment
COPIER>FUNCTION>CCD>DF-WLVL1
COPIER>FUNCTION>CCD>DF-WLVL2
Be sure to perform white plate data adjustment before
