Troubleshooting
Possible Cause
The left and right print positions have
not been adjusted for the center.
The margin at the top of the original or
print is too small.
The print paper is inappropriate.
The original has a solid black portion
at its top.
The print paper is loaded at a
horizontal grain direction.
There is any paper caught in the ADF
unit.
Action
The Paper Feed Tray is equipped with the
Horizontal Print Position Adjustment Dial.
Lower the tray, adjust the position, and
then perform proof copy to check the
position.
p.64
The margin of the original (top of the print
in the paper output direction) must be
(5 mm) at least. Lower the vertical print
position. If this adjustment is impossible,
reproduce an original with enough margin
and perform the master-making operation
again.
p.46
Use the recommended paper.
p.12
If an original has a solid black portion at
the top, printed copies may not properly
output. Replace the original in the reverse
direction and restart the master-making
process.
Load print paper with a vertical grain
direction.
Press the ADF Original Release Button or
turn the Release Original Dial and remove
the jammed paper.
