Correcting a Skewed Fold
A skewed fold will result if the paper has not been fed exactly at

The steps below de scribe in detail how to correct a skewed fold.
1. Remove the paper from the feed table.
2. Turn the skew adjustment knob to center the pointer in its
slot.
3. Reload the paper making sure there isn't too much clear ance
between the stack and the side guides.
4. Set the machine for a half (single) fold. This makes it easier
to determine which way to turn the skew ad just ing knob.
5. Run a trial piece.
6. If the fold is skewed, compare your sample with the drawings
below.
If the sample looks like "A", turn the skew
ad just ment knob counter-clockwise slightly.
If the sample looks like "B", turn the skew
ad just ment knob clock wise slightly.
7. Remove and reload the paper stack. This is

8. Run another trial piece and readjust if necessary.

sible without binding.
