1.9 SKEW ADJUSTMENT
1.9.1 MANUAL ADJUSTMENTS BY SERVICE TECHNICIAN
Before You Begin
These adjustments can be done by the service technician adjusting the set and adjustment
screws on the multi-folder unit.
The illustration above shows the positions of the three stoppers inside the machine. The
positioning of the stoppers is critical because this determines the types of folding.
Front and Rear
The terms "Front" and "Rear" are critical to understanding how paper is skewing during
folding. These terms are defined relative to the positioning of the paper in the paper path as
it feeds and exits.
"High" means the distance from the nip of the fold roller to the stopper is too far on one
end of the fence.
"Low" means the distance from the nip of the fold roller to the stopper is too short.
