- When a sheet is loaded along 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 sheets,
adjust the skew using the fold skew correction lever.
(Standard position of the lever is middle.)

Fulcrum Shaft
- The pressure of the fold roller is produced by the fold
roller spring of the roller link. If the roller shaft is posi-
tioned incorrectly in the roller support and the roller
link is pulled up forcibly using the clamp handle while
installing the second and fourth fold rollers, the fold

roller spring will be deformed. In that case, replace

Is the stopper tilted?
Sheet
- Fold a sheet and adjust the stopper tilt angle,
depending on the skew of the folded sheet.
Are the fold rollers stained?
- If the duplicator printed sheet is folded before it dries
out, the ink transfers to the fold roller and changes the
friction, then results in incorrect folding.
Instruct the operator to clean the fold rollers following
the "Maintenance" in the user's manual.
If the fold roller is worn out or deformed, sheet may be
folded askew. Check the roller condition.
