3.14.3 ADF SCANNING ADJUSTMENTS
Vertical Black Lines
Vertical black lines in scanned images may be caused by dust or scratches on the
ADF exposure glass. If the problem cannot be solved by cleaning the ADF
exposure glass, execute SP4018 (Scanner Optical Axis Adjustment).
1. Adjust the scanner stopping position with SP4018-003 (just input a new value).
2. Store this value in the machine with SP4018-004.
3. Adjust the ADF registration for the front side scan with SP6006-003.
4. Make a test copy to check that the problem has been solved.
