The stack height switch is a capaciti-
ve sensor that reacts to the density of
the paper stack. For this reason the
gap between stack and suction drum
can vary when the paper stack has
reached the work position depending
on the type of paper used.
The gap between stack and suction drum
should be 8 mm.
Ł
Set the gap to 8 mm by turning the setting screw (3).
A scale (4) facilitates this setting.
Ł
Lower the front stop (5) and slide
it against the paper stack.

This tiltable stop can also be
replaced by a stop rod (6).
The stop rod is attached to the
pile table with a lock screw (7).
The tiltable stop (5) must then
be moved up so that it does not
interfere with the stop rod.

a few sample sheets after all adjustments have been completed.
