Light paper grades easily cling to the curve of the suction drum.
Therefore the suction segment must be tilted in direction of the paper stop.
The inclination of the suction segment in this
direction has the effect that the paper is wrapped
around the suction drum (1).
The sheets are easily separated from the stack
and double sheets occur very rarely.

Vacuum setting for light paper grades:
For running light-weight paper, first try the suction segment setting as
described under "Basic Setting".
A steeper inclination is only necessary for special types of paper.
In the batch counting mode it may happen occasionally that a single sheet is fed
during the interval time.
This is caused by the fact that the suction drum continues to turn during the interval
time (although without vacuum). For light paper grades the friction between paper
and suction drum may be sufficient for detaching a sheet.
To prevent this, a special plate (2) can be placed
over the suction drum. This plate, which is pulled
out of the feed table, can cover the suction drum
to its highest point (3).
Sheet are no longer affected by the friction
of the suction drum.

Proceed as follows to pull out the plate:
• Loosen the screw (4).
• Insert a screwdriver in the hole (5).
• Pull out the plate.
• Tighten the screw (4).

Vacuum setting for heavy paper grades
Heavy paper grades do not easily cling to the curve
of the suction drum.
For this reason the suction segment must be tilted
in direction of the paper stack.
The inclination of the suction segment in this
direction has the effect that the paper is barely
wrapped around the suction drum (6).
This is sufficient because heavier paper grades
are more easily separated from the stack.
