CHAPTER 3 SADDLE STITCHER UNIT BASIC OPERATION
2. Controlling the Movement of Stacks
When a stack has been stitched (2 points), the paper positioning plate lowers so that the stack
will move to where the paper folding rollers come into contact with the stack and where the paper
pushing plate is located. The position of the paper positioning plate is controlled in reference to the
number of motor pulses coming from the paper positioning home position sensor (PI7S).
At the same time as the paper positioning plate operates, the guide plate lowers so that folding
may take place.
