Sub item Description level.
ADJ-X Use it to adjust the scanner image leading edge position (i.e., image read start position in sub scanning direction).
Method of adjustment
- if the non-image width is larger than indicated, decrease the setting.
- if an area outside the original is copied, increase the setting.
- an increase by '1' will move the image read start position toward the trailing edge by 0.1 mm (i.e., move the image read
area toward the trailing edge).
- if you have initialized the RAM of the reader controller PCB or replaced the reader controller PCB, enter the value
indicated on the service label.
Range of Adjustment 1 to 100 [Factory default/After RAM clear: 20]
Attention:
If you have changed the setting, be sure to record the new setting on the service label.

- if an area outside the original is copied, increase the setting.
- an increase by '1' will move the image read start position toward the front by 0.1 mm (i.e., move the image read area
toward the front).
- if you have initialized the RAM on the reader controller PCB or replaced the reader controller PCB, enter the value
indicated on the service label.
