Symbols Explanation Symbols Explanation
Cleaning is needed. Measurement is needed.
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.

Safety Precautions

Points to Note Before Servicing
• At servicing, be sure to turn OFF the power source according to the specified steps and disconnect the power plug.
• Be sure to disconnect the power plug on a regular basis and remove dust and dirt accumulated around the outlet with dry
cloth.
CAUTION:
Leaving the power plug connected for a long time in an environment having a lot of dust, moisture, or oily smoke will
cause a fire. (Because dust accumulated in the surrounding area will absorb moisture and cause an insulation failure)
• Be careful not to be injured by burrs of edges, sharp corners or protrusions.
CAUTION:
Hazardous area such as corners, edges, springs and other sharp sections may be remaining on products. Always be
aware of the presence of hazardous area to avoid injury caused by contacting and/or striking those area, by not over-
concentrating on service work.
Points to Note at Cleaning
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
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.
CAUTION:
English
CAUTION
DOUBLE POLE/NEUTRAL FUSING
The fuse may be in the neutral, and that the mains shall be disconnected to de-energize the phase conductors.
German
VORSICHT
ZWEIPOLIGE BZW. NEUTRALLEITER-SICHERUNG
Die Sicherung kann sich im Nullleiter befinden und das Hauptnetz muss abgetrennt werden, um die Phasenleiter
stromlos zu machen.
Points to Note when Tightening a Screw
When a thin plates is used in some parts for the light weighting purpose, warn the following.
In the case of a screw hole with a triangle mark near it as shown in the figure below, strongly tightening the screw may damage
or deform the screw hole.
In the case of a screw hole with a triangle mark, take care not to apply too much force when tightening the screw.

The components of this finisher are organized into 3 major blocks; feed unit, processing tray unit and stack tray unit.
Stack Tray Unit Processing Tray Unit Feed Unit
Overview of Electrical Circuitry
This machine's sequence of the operation is controlled by the finisher controller PCB.
Main control/functions of the Finisher Controller PCB
• Communicates to its host machine.
• The CPU on the Finisher Controller PCB contains a ROM for storing the operating sequence program.
• The Finisher Controller PCB receives various commands through the communication cable from its host to drive the motors,
and solenoids.
• It also sends sensor and switch information to its host through the communication cable.
• Records the setting value of service mode for the finisher to the CPU.

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.
Delivery Roller Inlet 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.
