• If misfeeds still occur after the
envelopes have been flattened,
load envelopes on the Wide LCT
one at a time and print them
individually.
• For details about how to load
envelopes, see "Envelopes",

Wrinkling occurs when gate
fold, letter fold-in, or letter
fold-out is applied.
Wrinkling can occur if gate
fold, letter fold-in, or letter
fold-out is applied to B4 JIS
, A3 , 8 1/2" 14", 11"
17" , 12" 18" , 8K
, or larger sizes of paper.
When applying gate fold, letter fold-in,
or letter fold-out to paper larger than
A4, we recommend you enable image
reduction and use paper no larger
than A4 .
When you print Z-folded
paper, the machine
indicates that the output tray
is full even though the output
paper on the tray is less than
the stack capacity.
The Z-fold support tray is not
set.
Set the Z-fold support tray for finisher
or multi-folding unit. For details about
how to add the Z-fold support tray, see
p.27 "When the Output Z-folded
Paper Is Less than the Stack Capacity".
Cannot print in duplex
mode.
"Apply Duplex" is set to [No]
for Tray 1-6.
In [Tray Paper Settings], under Tray
1-6, set "Apply Duplex" to [Yes].
Cannot print in duplex
mode.
You cannot select duplex
printing if the paper type is
set to [Label Paper],
[Translucent Paper], [OHP
(Transparency)], [Envelope],
or [Tab Stock].
In [Tray Paper Settings], under Tray
2-6, select a paper type other than
[Label Paper], [Translucent Paper],
[OHP (Transparency)], [Envelope],
and [Tab Stock].
The multi-folding unit outputs
sheets with creased edges
when gate fold is applied.
The paper is curled. Remove the paper, and then reload it
upside down. Alternatively, remove the
paper, and then reload it in the
opposite direction.
The position of the fold is
incorrect when letter fold-in
is applied to B5 sheet.
Multi-sheet fold has been
specified when only one
sheet is being printed.
Change the setting of letter fold-in so
that multi-sheet fold is not performed.
Depending on your machine, the
procedure of multi-sheet fold function
settings might be slightly different. For
details, refer to the procedure for your
machine.
Paper is bent. Paper may be bent when it is
ejected from the finisher
upper tray.
Change the output tray to the finisher
shift tray.
