CHAPTER 3   SADDLE STITCH 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 is executed by driving the rotary cam by the stitcher motor (M7S, M6S). The front

and rear stitcher units are operated with a time delay so as to prevent wrinkling of paper and to limit
the load applied to the power supply. (A time delay for initiating the stitcher motor startup current
helps decrease the load on the power supply.)

The stitcher home position sensor (MS7S, MS5S) is used to monitor the movement of the

rotary cam, enabling identification of individual stitcher operations. The presence/absence of staples
inside the staple cartridge fitted to the stitcher is detected by the staple sensor (MS6S, MS4S).

The alignment plates keep both edges of the stack in place while stitching takes place.
