7. STACKER SECTION (FS-604)
7.2.3 Stopper control
A. Stopper mechanism
The control of the stop position of the paper that has been conveyed to the stacker is made by 2 stoppers (sad-
dle stitching stopper and flat-stapling stopper).
The stop position of paper in the vertical direction is not the same for the stapling mode and for the folding, sad-
dle stitching and tri-folding modes.
In the stapling mode, the flat-stapling stopper [1] is set on the paper path by the pushing pressure by the spring
[2]. The flat-stapling stopper [1] determines the position of the leading edge of the fallen paper.
In the saddle stitching/folding/tri-folding mode, the flat-stapling release solenoids /Fr, Rr (SD7 and SD8) [4] turn
ON and evacuate the flat-stapling stopper [1] from the paper path. Then, the paper falls down to the saddle
stitching stopper [3] without contacting with the flat-stapling stopper.
The saddle stitching stopper motor (M18) [5] moves the saddle stitching stopper up and down in accordance
with the paper size. The saddle stitching stopper home sensor (PS23) [6] detects the home position.
