CHAPTER 3 SADDLE STITCHER UNIT BASIC OPERATION
2. Stitcher Unit Operation
The stitcher base unit consists of two stitchers and stitcher bases. The stitchers are fixed in
position, and are not designed to slide or swing.
Stitching operation is executed by driving the rotary cam by the stitch motor (M7S, M6S). The
front and rear stitcher units are operated with a delay in time so as to prevent wrinkling of paper and
to limit the load imposed on the power supply. (A delay in time for initiating the stitcher motor
start-up current helps decrease the load on the power supply.)
The stitching home position sensor (PS4, PS2) is used to monitor the movement of the rotary
cam, thereby enabling the identification of a single operation of the stitcher. The presence/absence
of staples inside the staple cartridge fitted to the stitcher is detected by the staple sensor (PS3, PS1).
The alignment plates keep both edges of the stack in place while stitching takes place.
