Adjustment to paper thickness
1. Switch on feeder and sheet travel.

3. Determine the setting values for the current
print job. The following formula is used for the
calculation: Stock thickness / 2
×
100
Example:
D
Stock thickness 0.1 mm:
0.1 / 2 = 0.05
×
100 = turn 5 notches to
the left.
D
Cardboard 0.8 mm:
0.8 / 2 = 0.4
×
100 = turn 40 notches to the
left.
4. Turn the control knob (Fig. 56/3) anti-clockwise
by the calculated number of notches.
