Symbols Used
This documentation uses the following symbols to indicate special information:
Symbol Description
Indicates an item of a non-specific nature, possibly classified as Note, Caution, or Warning.
Indicates an item requiring care to avoid electric shocks.
Indicates an item requiring care to avoid combustion (fire).
Indicates an item prohibiting disassembly to avoid electric shocks or problems.
Introduction
Memo
REF.
Indicates an item requiring disconnection of the power plug from the electric outlet.
Indicates an item intended to provide notes assisting the understanding of the topic in question.
Indicates an item of reference assisting the understanding of the topic in question.
Provides a description of a service mode.
Provides a description of the nature of an error indication.
Introduction
The following rules apply throughout this Service Manual:
1. Each chapter contains sections explaining the purpose of specific functions and the relationship between electrical
and mechanical systems with reference to the timing of operation.
In the diagrams, represents the path of mechanical drive; where a signal name accompanies the symbol ,
the arrow indicates the direction of the electric signal.
The expression "turn on the power" means flipping on the power switch, closing the front door, and closing the
delivery unit door, which results in supplying the machine with power.
2. In the digital circuits, '1'is used to indicate that the voltage level of a given signal is "High", while '0' is used to
indicate "Low".(The voltage value, however, differs from circuit to circuit.) In addition, the asterisk (*) as in
"DRMD*" indicates that the DRMD signal goes on when '0'.
In practically all cases, the internal mechanisms of a microprocessor cannot be checked in the field. Therefore, the
operations of the microprocessors used in the machines are not discussed: they are explained in terms of from
sensors to the input of the DC controller PCB and from the output of the DC controller PCB to the loads.
The descriptions in this Service Manual are subject to change without notice for product improvement or other
purposes, and major changes will be communicated in the form of Service Information bulletins.
All service persons are expected to have a good understanding of the contents of this Service Manual and all relevant
Service Information bulletins and be able to identify and isolate faults in the machine."

2.1.1 Basic Operation
0009-2508
The finisher is designed to deliver copies arriving from its host machine, and its modes of delivery include simple
stacking, job offset, and staple.
All operations involved in these modes are controlled by the finisher controller PCB, according to the appropriate
commands from the host machine.

Memo: The term job offset refers to shifting each sorting job, separating a single stack into several stacks.
2.1.2 Overview of the Electrical Circuitry
0009-2509
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 machine (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 communicates the finisher's various
states (information on sensors and switches) to the host machine through a serial communications circuit.
The ICs used on the finisher controller PCB are designed for the following:
<IC108 (CPU)>
Controls sequence of operations.
Contains sequence programs.
2-1
<IC105 (EEP-ROM)>
Backs up adjustment values.
Backs up initial setting data.
<IC107 (communications IC)>
Communicates with the host machine and the saddle stitcher unit.
<IC102 (regulator IC)>
Generates 5V.
<IC109 (regulator IC)>
Generates 3.3V.
The following figure shows the flow of signals between the finisher and the options controller.

2.2.1 Overview
0009-2510
This product consists of the Finisher unit and the Saddle Stitcher unit.
The Finisher unit simply stacks sheets delivered from a host machine, offsets a stack job, or staples and delivers the
sheets to the trays according to commands delivered from a host machine.
There are three delivery methods.

2.2.2 Constraction of the Control System
0009-2511
The copy sent from the host machine is delivered to the ejection tray, escape tray, or processing tray according to
the ejection type. Job offset or stapling is performed, according to the instruction from the host machine, for copy
delivered to the staple tray.
When ejecting from the processing tray, rear end assist guide is used in addition to the stack ejection roller to eject
2-3
the stack.
The feed motor (M101), stack ejection motor (M102), rear end assist motor (M109), escape feed motor (M112), and
inlet motor (M113) are step motors. These motors are rotated forward or backward by the microcomputer (CPU) in
the finisher controller PCB.
The following three sensors are provided in the copy delivery path to detect the arrival or passing of copies.
- Inlet sensor (PI103)
- Delivery path sensor (PI104)
- Escape tray path sensor (PI118)
Also, each ejection tray has sensors to detect the presence of copy on the tray.
First tray paper sensor (PI111)
Second tray paper sensor (PI112)
If the copy does not reaches or passes each sensor within prescribed time, the finisher controller PCB determines that
the jam has occurred and stops the operation. Then it notifies the host machine that a jam has occurred. When all of
the doors are closed after fixing the jam, the finisher checks whether copy is detected by any of the above three
sensors (inlet sensor, delivery path sensor, escape tray path sensor). If any of the sensors detects a copy, the finisher
determines that the jam is not fixed and sends jam processing signal to the host machine once more.
