CHAPTER 3 SADDLE STITCHER UNIT BASIC OPERATION
B.
Electrical Circuitry
The sequence of operations used for the saddle stitcher is controlled by the saddle stitcher
controller PCB. The saddle stitcher controller PCB has a microprocessor. This microprocessor is
used to control the sequence of operations and to handle serial communications with the finisher
controller PCB, driving solenoids and motors in response to the various commands from the fin-
isher controller PCB.
The saddle stitcher controller PCB is also used to communicate the state of various sensors and
switches to the finisher controller PCB in serial.
The functions of the major ICs mounted on the saddle stitcher controller PCB are as follows:
●
Q1
Controls the sequence of operations.
●
Q2
Contains the sequence program.
●
Q3
Controls the sequence of operations.
●
Q4
Handles IPC communications.
