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.

CAUTION:
1. As a general rule, do not use extension cords. Using an extension cord may result in a fire or electrical shock. If an
extension cord must be used, however, use one for local rated voltage and over, untie the cord binding, and insert the
power plug completely into the extension cord outlet to ensure a firm connection between the power cord and the
extension cord.
2. The socket-outlet shall be installed near the equipment and shall be easily accessible.
Notes Before Servicing
CAUTION:
At servicing, be sure to turn off the power source of the host machine according to the specified 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
CAUTION:
When performing cleaning using organic solvent such as alcohol, be sure to check that the component of solvent is
vaporized completely before assembling.
Notes On Assembly/Disassembly
Notes on Assembly/Disassembly
Follow the items below to assemble/disassemble the device.
1. Disconnect the power plug to avoid any potential dangers during assembling/disassembling works.
2. If not specially instructed, reverse the order of disassembly to reinstall.
3. Ensure to use the right screw type (length, diameter, etc.) at the right position when assembling.
4. To keep electric conduction, binding screws with washers are used to attach the grounding wire and the varistor. Ensure to
use the right screw type when assembling.
5. Unless it is specially needed, do not operate the device with some parts removed.
6. Never remove the paint-locked screws when disassembling.
7. During disassembly, reassembly or transportation of the printer, remove the cartridge if required. When the cartridge is out
of the printer, put it in a protective bag even in a short period of time to prevent the adverse effect of light.

Basic Configuration
Functional Configuration
The components of this finisher are organized into 3 major blocks; feed unit, processing tray unit and stack tray unit.
Overview of Electrical Circuitry
This machine's sequence of the operation is controlled by the finisher controller PCB.
The finisher controller PCB has the CPU(IC1), and the controller also controls the communication with the host machine in addition
to controlling this machine's operation sequence.
The CPU(IC1) on the finisher controller PCB contains a flash ROM used to store the operating sequence program.
The finisher controller PCB uses the UFDI 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.
The setting value of the service mode in the finisher is memorized in CPU(IC1).

2. Technical Explanation
Basic Operation
Outline
The finisher operates according to the commands that it receives from the host machine and ejects paper to the delivery tray.
There are four paper delivery methods.
• Non-sort stacking
• Shift-sort stacking
• Staple stacking
• Staple-free staple stacking
Basic operations of this finisher are described below.
1. The paper delivered from the host machine is fed by the inlet roller and delivery roller.
2. The trailing edge of the paper delivered by the delivery roller is pushed on the processing tray by the paper trailing edge
pushing guide.
3. The paper is fed toward the processing tray by the paddle. The return belt feeds the paper to the processing tray's stopper
and aligns paper in the feed direction.

2. Technical Explanation
4. 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.)
5. The operations described in steps 1 to 4 are repeated for each sheet to stack the sheets on the processing tray.
6. The stacked sheets are stapled or staple-free stapled (only when in the relevant mode).

Assist Guide
Paper Retainer
2. Technical Explanation
7. After being shifted, the paper stack on the processing tray that has been stacked by the assist guide is delivered to the
delivery tray.
8. After the paper stack has been delivered, the paper retainer holds down the stack in the delivery tray.
Initialization
The finisher performs the following initialization operation depending on the status.
Status Operation
At power ON If the target sensors*1 are aware of the home positions, initialization is not performed.
When recovering from sleep mode

2. Technical Explanation
1. After the delivery sensor (PS1) detects the trailing edge of the paper, the paddle motor (M10) runs to move the paddle unit
down. The paddle driven by the feed motor (M1) delivers the paper toward the processing tray. After a given time elapses,
the paddle unit is moved up.
2. After the delivery sensor (PS1) detects the trailing edge of the paper, the return belt motor (M2) runs to move the return belt
unit down. The delivered paper is pressed against the stopper by the return belt driven by the feed motor (M1) and aligned
in the feed direction.
After a given time elapses, the return belt unit is moved up.
NOTE:
Paper is not fed by the returned belt if the paper width is more than 297.0 mm or less than 120 mm or if the paper is special paper
or envelopes.

Alignment/Shifting Operation
■ Outline
The paper stacked on the processing tray is aligned in the width direction by the front and rear alignment plates.
Then, the paper is delivered to the delivery tray.
When shift sort is specified, the paper stacked on the processing tray is aligned to the front or rear and shifted to sort the paper
stack.
The front alignment plate is driven by the front alignment motor (M3) and the rear alignment plate by the rear alignment motor
(M4). The home positions of the alignment plates are detected by the front alignment HP sensor (PS4) and rear alignment HP
sensor (PS5).
