4. Scan image off-center adjustment
(RSPF mode)
This adjustment must be performed in the following cases:
* When the scan control PWB is replaced.
* When the EEPROM on the scan control PWB is replaced.
* When the scanner (reading) section is disassembled.
* When the scanner (reading) section is replaced.
* When U2 trouble occurs.
* When the RSPF section is disassembled.
* When the RSPF unit is replaced.
NOTE: To execute this adjustment, it is required that the Scan

Adjustment procedures
1)
Prepare the adjustment chart.
The adjustment chart can be made by the following proce-
dures. Use A4 (11" x 8.5") paper and draw arrow marks verti-
cally and horizontally on the front and the back surfaces. At the
same time, put marks of the lead edge, the trail edge, the front
end, and the rear end as well as the identification marks of the
front surface and the back surface.
