When a single sheet passes through, the scanner element (13-
6) stays in the off-position. When a double sheet is fed, the
scanner is activated and drawn into the microswitch (13-7) and the
double is stopped. Only the sheet feed is switched off. To remove
the double sheet, raise the arm. After fault removal, reset the
"sheet-feed" start switch.
For thin paper, loosen the knurled screw and reset the lever
spring tension. Afterwards retighten the knurled screw.

BAUMSET ADJUSTMENT
1.0 Adjustment of Folding Rollers
Folding accuracy is determined largely by precise adjustment of the folding rollers.
Using the Baumset precision adjustment device, the correct setting of the rollers can be made simply by inserting the
appropriate paper thickness between the adjustment plates. (See Figure 14)
With multiple thicknesses, insert single strips of the paper being folded equal to the number of sheets passing through
that roller combination..
Since the adjustment spindle acts directly on the folding rollers, clearance settings are exact.
Another method for setting the folding rollers is to insert paper strips between them by touch and adjusting the
pressure by turning the knurled screw.
The numbers on the Baumset adjustment knobs correspond to the buckle-plate numbers into which the sheet is fed. All
upper buckle plates have odd numbers while the plates below are even.
The Baumset adjustment device is correctly zeroed at the factory. If any adjustment is necessary, strips of single paper
thickness should be placed under every adjustment plate. The folding rollers are then reset by drawing strips of uniform
thickness through the appropriate pair of rollers as far as possible to the other side.
At the same time, the knurled screws are adjusted so that the strips can be withdrawn when medium drag is felt. When
this operation is complete, the dial rings are reset to zero.
