2. Saddle Stitch Unit Operation
The Saddle Stitch 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.
