Stitcher Unit Operation - Canon SADDLE FINISHER K3 Service Manual

CHAPTER 2 OPERATION OVERVIEW

12.4.2 Stitcher unit operation

The stitcher mount unit consists of two stitchers and stitcher mounts on a unit mount. The
position of the stitchers are fixed and there is no sliding movement involved. Stitching is
controlled by the rotary cams, which are driven by the stitcher motors (M37, M36). There is
a time lag between operation of the front and rear stitcher units. This is to prevent creasing
of the paper between the staples and to reduce the power load by staggering generation of
the current for starting the stitcher motors.
The stitcher operation home position sensors (MS34, MS32) monitor the movement of the
rotary cams and detect whether one stitching operation has been performed. The staple sen-
sors (MS33, MS31) detect whether there are any staples in the staple cartridge loaded in the
stitcher. The jogging plates hold the edges of the paper in place during stitching.
