14. FINE ADJUSTMENTS AND CORRECTIONS
Fold Lengths
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 entire width of the sheets.
Use the cursor key in the BASIC menu to choose
fold plate 1 or 2 and change setting value by pressing key
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 not fed 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 folder (1).
1
• To make the deviation more obvious,
exaggerate the skewed fold by hand (2).
2
• Open the folded sheet and place it in front of the roller infeed section. (3).
3
• By turning the adjustment wheel on the register
table (4), the register rail must be adjusted in such
a way that the leading edge of the paper is parallel
to the fold rollers.
