1. This chapter discusses the purpose and role of each of the finisher’s functions, and the principles
of operation used for the finisher mechanical and electrical systems. It also explains the timing at
which these systems are operated. The 
 symbol in drawings indicates transmission of me-
chanical drive, and signals marked by 
 together with the signal name indicates the flow of
electrical signals.
2. In descriptions of digital circuits on the finisher, “1” indicates a high signal voltage level, while
“0” indicates a low signal voltage level. Voltage values differ according to circuit.
A microprocessor is used on the finisher. A description of microprocessor operation is omitted in
this chapter as it is practically impossible to check internal operation of the microprocessor.
Descriptions in this chapter also assume that PCBs will not be repaired at user sites. For this
reason, descriptions of circuits on PCBs is limited to block diagrams. Two types of block dia-
grams are provided for separate functions: diagrams indicating details from sensors up to input
sections of major PCBs, and diagrams indicating details from the output sections of major PCBs
up the loads.

I.
BASIC OPERATION
A.
Outline
The finisher is designed to deliver copies arriving from its host machine, and its modes of deliv-
ery include simple stacking, job offset
 (Note)
, and staple.
All operations involved in these modes are controlled by the finisher controller PCB, according
to the appropriate commands from the host machine.
In the case of the Saddle Finisher, copies from the host machine may be routed to the saddle stitch
unit.

Note:
The term job offset refers to shifting each sorting job, separating a single
stack into several stacks.

CHAPTER 2   FINISHER UNIT BASIC OPERATION
B.
Outline of Electrical Circuitry
The finisher’s sequence of operation is controlled by the finisher controller PCB. The finisher
controller PCB is a 16-bit microprocessor (CPU), and is used for communication with the host ma-
chine (serial) in addition to controlling the finisher’s sequence of operations.
The finisher controller PCB responds to the various commands coming from the host machine
through a serial communications line to drive solenoids, motors, and other loads. In addition, it com-
municates the finisher’s various states (information on sensors and switches) to the host machine
through a serial communications circuit.
In the case of the Saddle Finisher, the finisher controller PCB not only communicates with the
saddle stitch controller PCB but also communicates the saddle stitch unit’s various states (information
on sensors and switches) to the host machine.
The ICs used on the finisher controller PCB are designed for the following:
IC1 (CPU)
Controls sequence of operations.
IC2 (EP-ROM)
Backs up adjustment values.
IC3
Contains sequence programs.
IC6/IC7 (RAM)
Backs up initial setting data.
IC4 (communications IC)
Communicates with the host machine and the saddle stitch unit.
IC9 (regulator IC)
Generates PWM.
Figure 2-102 shows the flow of signals between the finisher and the options controller.
