- Using the SST, download the data stored in the
RAM of the reader controller PCB.
- Print out the user mode/service mode data.
1) Turn on the power, and execute the following
service mode item:

2) If the data has successfully been downloaded
using the SST before the replacement, upload
the data.
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)

(adjustment of main scanning position for ADF
fixed reading)
