tion for feed direction automatically.
If the leading- and trailing-edge posi-
tions of a scanned image are improper,
perform this adjustment.

tion-related part such as the reading unit or
the start switch PCB on which a registration
sensor is installed or after replacing the
control PCB recording the adjustment data.
This mode can be used together with
other adjustment items. For details, refer to
[All Adjustment].

section.
Note:
If the shading sheet is used, it can be
shared with "Light Adjustment".
2) To have the black leading edge and the
white trailing edge, whose width is 2 mm or
more.
3) Paper size is basically A4 size or LTR size,
and the above-mentioned shading sheet,
and must have the following range: Width:
200 to 220 mm; Length: 130 to 297 mm.
