16. FINE ADJUSTMENTS AND CORRECTIONS
Fold Length Fold variations may occur if the fold plate stops are not set accurately or
if the folding speed is changed. The fold is off across the whole width of
the sheets (as opposed to a skewed fold).
Corrections of the fold length are made by turning
the fine adjustment screw (1).

A change in the folding speed also changes
the fold length.
Therefore the set-up speed must be
maintained.
Skewed Folds Skewed (out-of-square) folds occur when the paper is fed not at right angles with
respect to the fold rollers.
This can be corrected as follows:
• Mark the leading edge of a sheet and feed it
through the fold unit (2).
• To make the deviation more obvious, exaggerate
the skewed fold by hand (3), (4).
• Open the folded sheet and place it in front of
the roller infeed section (5).
• Correct, as shown on the following page.
