AR-M550/M620/M700 SETTING AND ADJUSTMENTS 7 - 27
This adjustment is needed in the following situations:
• The MFP control PWB has been replaced.
• The EEPROM on the MFP control PWB has been replaced.
• The scan control PWB has been replaced.
• The EEPROM on the scan control PWB has been replaced.
• The scanner (reading) section has been disassembled.
• The scanner (reading) unit has been replaced.
• U2 trouble has occurred.
• The SPF section has been disassembled.
• The SPF unit has been replaced.
This adjustment is intended to adjust the scanner read position in SPF-
mode front face scan.
An incorrect adjustment would deviate the scanner stop position from
the required position, thus possibly causing a shadow of the original
table to appear at the leading edge of an image generated by SPF
(front-face) mode scan.
1) Make a copy in SPF (front-face) mode, and make sure that the
printed image at the leading edge of the copied image is free from
shadows.
If the printed image at the leading edge of the copied image contains a
shadow of the original table, then do the following steps.
2) Go through the modes specified in Simulation 53-8.
3) Enter the adjustment value and press the Start key.
Repeat the above adjustments until an acceptable result is obtained.
