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.

Notes Before Servicing
CAUTION:
At servicing, be sure to turn off the power source 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.
Points to Note when Tightening a Screw
For reduction in weight, thin plates are used in some parts of this machine.
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.

Basic Configuration
Functional Configuration
The components of this puncher unit are organized into 3 major blocks: punch unit, punch slide unit and punch waste accumulation
unit.
Punch Waste Accumulation Unit
Punch Slide Unit
Punch Unit
Overview of Electrical Circuitry
The operation sequence of the puncher unit is controlled by the puncher controller PCB.
The puncher controller PCB has a 32-bit CPU that performs sequence control. The puncher controller PCB receives various
commands from the finisher controller PCB to drive the motors. And it controls the operation of the puncher unit according to the
detection states of the sensor.

Basic Operation
Outline
Basic operations of this puncher unit are described below.
■ When in precision priority mode (normal mode)
1. When paper is fed from the upstream connection machine to the puncher unit, the punch slide unit performs horizontal
registration.

2. After the paper is fed from the position where the punch inlet sensor (PS301) detects the paper trailing edge to a given
position, the paper is switched back and fed until it bumps against the paper stopper guide.
