Problem
Although [Multi-Up Print]
was executed, nothing is
printed on one side.
The vertical print positions
have been shifted.
Papers are loaded on the
print drum (cylinder).
Curled printed papers are
output.
The printed papers that have
been output are not neatly
piled up in the paper receiv-
ing tray.
Point to check
Check if an original was
placed while the message
"Place Another Original and
Press Start Key" was dis-
played.
Check if the [STOP] key was
pressed while an original
was being scanned.
Check if the vertical print
position adjustment dial on
the paper feed tray is set to
the standard position.
Check if the margin at the
top of the printed paper is
enough.
Check if the printed paper
has a wide solid portion at its
top.
Check if appropriate papers
are used.
Check if the paper grain
(flow of the grain) is aligned
with the paper feeding direc-
tion.
Check if the positions of the
receiving tray paper guides
and paper stopper are
appropriate.
Check if the position of the
paper-feed setting lever is
appropriate.
Action
If the specified time has elapsed before the second
and subsequent originals are placed, master making
automatically starts. Any sections that could not be
scanned remain as margins.
If the time is too short, change [Multi-Up Interval]
(A 109) under [Admin].
If you press the [STOP] key while an original is
scanned, scanning is interrupted.
Do not press the [STOP] key until all of the originals
are scanned.
Lower the paper feed tray, and then turn the vertical
print position adjustment dial. After adjustment,
check the print position on the proof copy.
(A 70 "Adjusting the Print Position [PRINT POSI-
TION]")
The margin at the top of the printed paper (leading
edge in the paper output direction) must be at least
5 mm (3/16 inches). Lower the horizontal print posi-
tion, and then print. If it is not possible to lower the
print position, reduce the size of the original to allow
enough margin and perform master making again.
(A 51 "Enlarging or Reducing the Size of the Origi-
nal [Size]")
If a printed paper has a wide solid portion at its top
(leading edge in the paper output direction), papers
are more likely to stick to the print drum (cylinder).
Set the original upside down and perform master
making again. For this operation, it is convenient to
use [Rotate] under [Renew Page]
Use papers that are suitable for this machine.
(A 14 "Size and weight")
Place the paper so that its grain is aligned with the
paper feeding direction. (A
jams and paper feeding failures")
Fit the receiving tray paper guides and the paper
stopper to the paper size.
For thick papers, slightly widen them.
If you have adjusted the vertical position on the
paper feed tray, shift the receiving tray paper guides
in the same direction.
(A 29 "Setting up the paper receiving tray")
Select the position of the paper-feed setting lever
according to the paper type.
