INTRODUCTION
2.Outline of the Manual
This Service Manual contains basic information needed to service the Image Reader-A1/
iR5000i/iR6000i and its accessories (i.e., side paper deck, shift tray) in the field, conducted
for the purpose of maintaining its product quality and a specific level of performance. A
separate Service Manual is made available for each of its accessories (except for the side paper deck and shift tray); for details, refer to the appropriate manual.
This Service Manual consists of the following chapters:
1. System Unit
Chapter 1Introduction:features, specifications, names of parts, func-
tions, operation, system configuration, routine maintenance by the user
Chapter 2Main Controller:functional construction, outline of electrical
circuitry, principles of operation of the image
processing system, power supply
Chapter 3Installation:site conditions and installation procedure,
relocation of the machine, installation of accessories
2. Reader Unit
Chapter 1Basic Operation:functional construction, outline of electrical
circuitry, basic sequence of operations
Chapter 2Original Exposure System:principles of operation of the exposure sys-
tem, timing of operation, disassembly/assembly and adjustment
Chapter 3Image Processing System:principles of operation of the image process-
ing system, timing of operation, disassembly/
assembly and adjustment
3. Printer Unit
Chapter 1Introduction:safety of the laser, image formation, auxiliary
processes
Chapter 2Sequence of Operations:basic operations, outline of electrical cir-
cuitry, basic sequence of operations
Chapter 3Laser Exposure System:principles of operation of the laser exposure
system, timing of operation, disassembly/
assembly and adjustment
Chapter 4Image Formation System:principles of operation of the image forma-
tion system, timing of operation, disassembly/assembly and adjustment
Chapter 5Pickup/Feeding System:principles of operation of the pickup/feeding
system, timing of operation, disassembly/
assembly and adjustment

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.
In the diagrams,
accompanies the symbol
represents the path of mechanical drive; where a signal name
, the arrow indicates the direction of the electric signal.
The expression “turn on the power” means flipping on the power switch, closing the
front cover, and closing the delivery unit cover, 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.

INTRODUCTION
Important!
Be sure to turn off the main power switch and disconnect the power plug before starting
to disassemble the machine; in addition, keep the following in mind for the work:
1.In printer mode, turning off the main power switch can result in the loss of data being
processed. Check to make sure that the Execution/Memory lamp on the control panel
is off before operating the main power switch.
2.Do not turn off the main power switch while downloading is taking place. Otherwise,
the machine may become disabled.
3.The cassette heater and the drum heater remain powered as long as the environment
switch and the heater switch are on (even when the main power switch is off).
4.Not all power is removed when the front cover is opened if the main power switch is
on, requiring care.

1.1.5 Variety of Delivery Processing (with accessories)
Finishing: 1-point or 2-point stapling (Finisher)
Saddle stitching: middle binding and folding for delivery (Saddle Finisher-F2 only)
Punching: making binding holes for delivery (Puncher Unit)
1.1.6 Printer T ype
The machine possesses printer functions from the printer mechanisms of the iR5000/
6000; when combined with the Image Reader-A1, it provides functions expected of conventional copiers.
1.1.7 Addition of the Diff erential PCB
The differential PCB is an addition provided to send signals from the image reader to the
main controller of the machine.
