Explanation of Symbols
The following symbols are used throughout this Service Manual.
Symbols Explanation Symbols Explanation
Check Remove the claw.
Check visually Insert the claw.
Check the noise. Use the bundled part.
Disconnect the connector. Push the part.
Connect the connector. Plug the power cable.

The following rules apply throughout this Service Manual:
1. Each chapter contains sections explaining the purpose of specic 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 ipping 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 eld. 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.

Notes Before Servicing
Caution:
At servicing, be sure to turn off the power source according to the specied steps and
disconnect the power plug.
Caution:
Do not turn off the power switch when downloading is under way.
Turning off the main power switch while downloading is under way can disable the
machine.
Points to Note at Cleaning

Overview of Electrical Circuitry
The nisher's sequence of the operation is controlled by its nisher controller PCB.
The nisher controller PCB has the 16-bit CPU, and the controller also controls the
communication with the host machine in addition to controlling the nisher's operation
sequence.
The CPU on the nisher controller PCB contains a ash ROM used to store the operating
sequence program.
The nisher controller PCB uses the serial communication line to receive various commands
from its host to drive the motors. It also uses serial communications to send information on
the sensors and switches to its host.

Basic Operation
Outline
Basic operations of this nisher are described below.
(1) The paper delivered from the host machine is fed by the inlet roller, feed roller, and
delivery roller.
Feed Roller
Delivery Roller
Inlet Roller
(2) The paper delivered by the delivery roller is stacked on the processing tray by the
paddle. A paddle and a paper return paddle are used to align paper in the feed direction.
If two or more sheets with a length of 150 mm or more are stacked, the tray auxiliary
guides slide out.

(3) The alignment plates are used to align paper in the width direction. (In the illustration
below, paper is aligned with reference to the central reference position.)

(4) The operations described in (1) to (3) are repeated for each sheet to be stacked on the
processing tray.
(5) The stacked sheets are stapled (only in the staple mode).

The feed unit feeds the paper delivered from the host machine and feeds it to the processing
tray unit.
Two sensors, an inlet sensor (S1) and a delivery sensor (S2), are provided along the paper
feed path in the feed unit to detect the paper feed state and jam.

Stacking Operation
The paper delivered from the delivery roller is stacked on the processing tray and the paper is
aligned in the feed direction.
How paper is delivered from the delivery roller and stacked on the processing tray is
described below.
(1) When two or more sheets with a length of 150 mm or more are stacked, the tray
auxiliary guide motor (M6) operates after lapse of the specied time since detection of
paper by the inlet sensor (S1), thus sliding out the tray auxiliary guides.

(2) After the specied time has lapsed since paper has passed through the delivery sensor
(S2), the paddle motor (M3) operates to rotate the paddle once to stack the paper on the
processing tray.
The stacked paper is pressed against the stopper by the paper return paddle which is
driven by the delivery motor (M2), thus aligning the paper in the feed direction.
