CHAPTER 3 SADDLE STITCH UNIT BASIC OPERATION
B.
Electrical Circuitry
The sequence of operations used for the saddle stitch is controlled by the saddle stitch control-
ler PCB. The saddle stitch 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 finisher control-
ler PCB.
The saddle stitch 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 stitch 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.
