INTRODUCTION
2 Outline of the Manual
This Service Manual contains basic information needed to service the iR2200/iR2800/
iR3300 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 1General Description: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

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

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, 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 indica te “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.
