6. SADDLE STITCHING PROCEDURE
Adjust the position of the folding back guide roller.
Loosen the locknut, and move the folding back guide roller to the trail edge using the knobscrew. This holds down the
booklet and prevents folding misalignment.
If folding only a few sheets which are soft, decrease the gap between the folding stoppers.
Loosen the four knob screws, and lower the top folding plate. Normally use this folding plate in the raised position.
When processing many sheets of paper, using with this folding plate lowered will cause paper jams.
When stitching position is not perpendicular to paper
Adjust the angle of the saddle stitching stopper.
Release the lock plate with the finger, and turn the adjustment dial.
For the condition shown in the left figure A, rotate the adjustment
dial in the counterclockwise direction.
For the condition shown in the right figure B, rotate the adjustment
dial in the clockwise direction.
After adjusting, fit the lock plate into the groove on the lock dial.
When booklet alignment is poor at the belt stacker
Change the conveyance time of the belt stacker at accessory menu. (
Refer to page 65.)
If there are too many sheets, or when paper is thick, set a long conveyance time.
If booklet alignment is still poor after adjusting the conveyance time, replace the paper guide wheel with one for large
size paper. (Not available for paper less than 121 mm/4.76 inch)
If booklet alignment is still poor, loosen the knob screw and move the paper guide wheel to the main body.
