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.
ޓIn the diagrams, represents the path of mechanical drive; where a signal name accompanies the symbol ,
the arrow indicates the direction of the electric signal.
ޓThe 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."

Chapter 2
2.1.1 Overview
0001-2403
The finisher consists of the following 4 blocks: delivery assembly, intermediate processing tray assembly, stapler
assembly, stack tray assembly.
It is also equipped with a relay delivery assembly used to move paper from its host machine.
The following is a functional diagram of the finisher.

2.1.2 Overview of the Electrical Circuitry
0001-2405
The various operational sequences of the finisher are controlled by the finisher control PCB, which is a 16-bit CPU.
The CPU handles serial communications with the host machine in addition to executing sequential control of
machine operation.
The CPU on the finisher controller PCB is equipped with a ROM containing an operation sequence program.
The finisher controller PCB drives the motors in response to various commands coming from the host machine
through the serial communication line.
Moreover, the finisher controller PCB communicates the states of the sensors and switches to the host machine
through the serial communication line.

1) The front/rear aligning plate moves to a specific point to suit the size of the paper coming from the host machine.
2) The inlet roller and the delivery roller serve to move forward the paper coming from the host machine.

3) When the trailing edge of paper moves past the delivery roller, the stack delivery roller moves down to catch the
trailing edge of paper; thereafter, the stack delivery roller rotates to pull in the paper until it comes into contact
with the return belt.

4) The return belt forces the trailing edge of paper against the trailing edge guide plate to put the paper in order. The
stack delivery roller moves up to make space.

5) When the return belt has moved up to make space, the aligning plate (front, rear) moves to put the paper in order

in cross-feed direction.

6) When the paper has been put into order in cross-feed direction, the return belt comes into contact to remove the
skew (that may have occurred during alignment in cross-feed direction).

7) The machine repeats steps 1 through 6 above to put the sheets together into a stack.
8) The stack delivery roller moves down to force down the stack of sheets.
F-2-9
9) The stack delivery roller stops where the trailing edge of paper is 5 mm in front of the stack roller nip point.
F-2-10
10) When the stack delivery roller has moved up to make space, the paddle rotates in keeping with the movement of
the stacking wall, thereby permitting the stack of sheets to slide down the stacking wall.
F-2-11
11) The stacking wall moves to home position to put the edges of sheets in the stack flush. At this time, the paddle
forces the stack of sheets in place from above.
