2.3.1 After Replacing the
Reader Controller PCB
iR5570 / iR6570
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-

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
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.

c. original feed speed (magnification) adjustment
4) Make adjustments using the following service
mode items:
