Fig. 56 Double sheet detector above the tape
driving roller
The double sheet detector above the suction tape
drive roller consists of a cross bar (Fig. 56/2) that
can be equipped with 1...24 feeler rollers (Fig. 56/1).
It detects
D double sheets,
D bundles (multiple sheets),
D - depending on number and position of the
feeler rollers - paper bits of different sizes.
Adjust the tear-off detector/multiple-sheet detector at
the control knob (Fig. 56/3). The control knob has a
notch division of 1/100 mm.
Adjustment to paper thickness
1. Switch on feeder and sheet travel.
2. Turn the control knob (Fig. 56/3) clockwise until
the double sheet detector is just activated.
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.
