5.4.5.3 After Replacing the Reader Controller PCB
0011-8740
iR7105 / iR7095
Before Starting the Work (backing up the data)
If possible, perform the following:
- Using the SST, download the data stored in the RAM of the reader control-
ler PCB.
- Print out the user mode/service mode data.
1) Turn on the power, and execute the following service mode item:
COPIER > FUNCTION > CLEAR > R-CON
2) If the data has successfully been downloaded using the SST before the re-
placement, upload the data.
3) Set the values indicated on the service label for their respective service
mode items.
COPIER > ADJUST > ADJ-XY > ADJ-X (adjustment of image read start
position in sub scanning direction; image lead edge)
COPIER > ADJUST > ADJ-XY > ADJ-Y (adjustment of image read start
position in main scanning direction; horizontal registration)
COPIER > ADJUST > ADJ-XY > ADJ-S (adjustment of shading correction
data measurement position)
COPIER > ADJUST > ADJ-XY > ADJ-Y-DF (adjustment of main scanning
position for ADF stream reading)
COPIER > ADJUST > ADJ-XY > ADJ-Y-FX (adjustment of main scanning
position for ADF fixed reading)
COPIER > ADJUST > ADJ-XY > ADJ-X-MG (fine-adjustment of magnifi-
cation in sub scanning direction for copyboard reading)
4) Execute the following service mode item:
COPIER> FUNCTION> CCD> CCD-ADJ (shading correction based on
standard white plate)
5) Turn off and then on the power.

COPIER > ADJUST > ADJ-XY > ADJ-Y-DF (adjustment of main scanning
position for ADF stream reading)
COPIER > ADJUST > ADJ-XY > STRD-POS (adjustment of CCD read po-
sition for ADF stream reading)
COPIER > ADJUST > ADJ-XY > ADJ-X-MG (fine-adjustment of magnifi-
cation in sub scanning direction for copyboard reading)
FEEDER > ADJUST > DOCST (adjustment of original stop position for
ADF pickup)
FEEDER > ADJUST > LA-SPEED (adjustment of original transport speed
for ADF stream reading)
4) Execute the following service mode items:
COPIER> FUNCTION> CCD> CCD-ADJ (shading correction based on
standard white plate)
COPIER> FUNCTION> CCD> DF-WLVL1 (ADF white level adjustment;
for copyboard reading)
COPIER> FUNCTION> CCD> DF-WLVL2 (ADF white level adjustment;
for stream reading)
5) Turn off and then on the power.
MEMO:
In the case of the model with the DADF-M1 (outside Japan: iR7086), the
ADF-related service mode data is stored in the RAM of the reader controller.
As such, if you have initialized the RAM on the reader controller PCB or re-
placed the PCB, it is important that you newly enter service mode settings
and execute appropriate adjustment items.
