Solution:

Adjust the deviation.

The multi-folding unit has three adjusting screws (L1, L2, and L3) to adjust deviation.

<How to adjust the folding deviation>

This procedure is the same for L1, L2, and L3.

1Open the front cover of the multi-folding unit.

2Remove the mounting screw.

If the mounting screw is attached to the adjusting screw hole, unfasten it.

3Turn the adjusting screw to adjust the deviation.

  • To increase the length at the bottom part of paper, turn the screw clockwise.

  • To decrease the length at the bottom part of paper, turn the screw counterclockwise.

4Attach the mounting screw to fasten the adjusting screw.

If the mounting screw is attached to the adjusting screw hole, fasten it.

5Close the front cover of the multi-folding unit.

Note

  • For multi-sheet folding, folding deviations of the innermost sheet will be adjusted.

  • If the deviation is large, the paper may be skewed. For further information, see Paper Skew.
