Wrinkled Sheets
The buckle chute guide is installed
incorrectly or deformed.
- When the buckle chute at the infeed (entrance) side
is deformed as shown above, the sheet may hit the
guide and cause wrinkles. If the buckle chute guide
is deformed by more than 0.5 mm (0.02”), correct
the buckle chute guide.
If the jammed sheet is pulled by force to remove,
that may deform the guide.
- The buckle chute guide is installed on the side plate
by inserting the edge of the 1.6 mm (0.06”) thick-
ness spacer into the 2 mm (0.08”) width slot. The
spacer should be fixed on the infeed (entrance) side
of the slot. If not, that changes the position of the
buckle chute and results in the wrinkles on the
folded sheet.
The deflector is deformed.
- If the deflector is deformed and does not align with
the fold roller at the center, the sheet path is
blocked there and may cause wrinkles.
Remove the deflector and flatten it out. [Distortion:
within 0.1 mm (0.004”) ]
- When removing the jammed sheet on the deflector,
if it is pulled by force, that may deform the deflector.
Instruct the operator how to remove the jammed
sheet.
Not deformed
like this.
Fit on the infeed
(entrance) side

The sheets are curled or concave.
- The sheets immediately after printed or left in the
humid place may shape as shown above. If those
shaped sheets pass through the rubber rollers, that
may cause wrinkles on the folded sheet. Instruct the
operator to flatten out or dry the sheets before
folding.
[Additional Information]
- The wrapping of the sheets blocks the humid-
ity. If the wrapping is opened and left for a
long time, the sheet becomes damp around
but dry inside. Therefore, the sheet becomes
concave.
- The recycled papers are more likely to be
effected by the humidity.
