3) Set the values indicated on the service label for
their respective service mode items.
COPIER > ADJUST > ADJ-XY > ADJ-X (ad-
justment of image read start position in sub scan-
ning direction; image lead edge)
COPIER > ADJUST > ADJ-XY > ADJ-Y (ad-
justment of image read start position in main
scanning direction; horizontal registration)
COPIER > ADJUST > ADJ-XY > ADJ-S (ad-
justment 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 > STRD-POS
(adjustment of CCD read position for ADF
stream reading)
COPIER > ADJUST > ADJ-XY > ADJ-X-MG
(fine-adjustment of magnification in sub scan-
ning 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 read-
ing)
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 (out-
side Japan: iR7086), the ADF-related service
mode data is stored in the RAM of the reader con-
troller. As such, if you have initialized the RAM
on the reader controller PCB or replaced the PCB,
it is important that you newly enter service mode
settings and execute appropriate adjustment
items.
