Sheet Guide
Front Stop
Sheet Guide
- When a sheet is loaded so that the sheet edge
touches the front stop and the sheet guides are
aligned with the sheet edge, the guides should be
parallel to the sheet.
- If the sheet guides are not parallel to the sheet, see
Section [3-1: Sheet Guides Right Angle and Parallel
Adjustment] and adjust the sheet guide.
Roller pressure (spring force) is not
even at front and rear.

Spring
Stopper
Roller Lever
- The pressure of the fold roller is produced by the
spring of the roller lever. When installing the second
and fourth fold rollers, if the roller lever positions
incorrectly but is pulled up by force, the spring will
be extended. In case that, replace the spring.
- There should be a gap of 0.1 mm (0.004") between
the stopper and roller lever (at front and rear), when
the lever is pulled up.
If there is no gap in-between, the pressure of the
fold roller changes. See Section [3-7: Stopper
(Roller Lever) Position Adjustment] .

Stopper
Sheet
- To adjust the stopper tilt angle, fold a sheet and
adjust the stopper depending on the shift of the
folded sheet. See Section [3-5: Buckle Chute
Stopper Parallel Adjustment].
Fold rollers are contaminated.
Especially the stencil printed sheet, if the
sheet is folded before it drys out, the ink
adheres to the fold roller and changes the
friction and results in incorrect folding.
- Instruct the operator to clean the fold rollers
following the instruction of "Maintenance" in the
operation manual .
