Standard Folds

Skew Adjustments

Folds that are not perfectly parallel to the
leading and trailing edges of the sheet can be
corrected with the skew adjustment knob (8).
NOTE
Before making any skew adjustments, be sure
the paper thickness adjustment (see page 13)
is properly set for the paper being folded.
Running thick paper with a setting for thin
paper can sometimes cause skewed folds.
To evaluate skewed folds:
1. Unfold the skewed sheet.
2. Observe whether the end of the fold at the
right side of the sheet is further or closer to
the leading edge of the sheet than the end
of the fold at the left side.
NOTE
The top of the skew adjustment knob can be
reached without folding up the feed table or
unloading paper from the feed area.
To make a skew adjustment:
1. Rotate the skew adjustment knob two or
three turns in the appropriate direction
2. Remove and reload the paper stack.
3. Fold three or four trial sheets and observe
the effect on the squareness of the folds.
4. Further adjust the skew knob and make
trial folds until the folds are parallel with
the leading and trailing edges of the sheet.
