k. Press SW1 or SW2 on the Finisher Controller PCB as necessary.
• Each press of SW1 increments the winding amount in 0.72 mm increments.
• Each press of SW2 decrements the winding amount in 0.72 mm increments.

l. Repeat steps a. though f. twice. Check that the winding amount is within the standard in both times.
m. Turn the Copier OFF, and set all bits of SW3 to OFF.
This completes the adjustment.
5. Setting the Upward Curling Sheet Mode
(1) Outline
Upward curling of sheets stacked on the Tray sometimes increases depending on the state of the
copy paper. If this happens, the stacked sheets are pushed out by subsequent output sheets. This
sometimes increases the alignment deviation.
See the stacking example below.
Fig. 7-013
If this happens:
a. Turn over the paper in the Paper Tray and load the paper again.
If upward curling is larger than before the paper was loaded again, return the paper in the Paper
Tray to its original orientation.
From here on, too, if upward curling is excessive, resulting in stacked sheets being pushed out
by subsequent output sheets, try setting the upward curling sheet mode as indicated.
