INTRODUCTION
This Service Manual contains basic data and figures on the ADF for the iR600 needed
to service the machine in the field.
CHAPTER 1 General Description introduces the ADF's features and specifications,
and shows how to operate the ADF.
CHAPTER 2 Basic Operation provides outlines of the ADF's various mechanical
workings, and explains the principles used for the ADF's various control mechanisms in
view of the functions of electrical and mechanical units and in relation to their timing of
operation.
CHAPTER 3 Mechanical System shows how the ADF's various mechanical workings
are constructed, and how the ADF may be disassembled/assembled and adjusted.
CHAPTER 4 Maintenance and Servicing provides tables of periodically replaced
parts and consumables/durables and scheduled servicing charts.
CHAPTER 5 Troubleshooting provides tables of maintenance/inspection, standards/
adjustments, and problem identification (image fault/malfunction).
APPENDIX contains a general timing chart and general circuit diagrams.
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.

CHAPTER 1 GENERAL DESCRIPTION
I . FEATURES
1. First Page First
The machine helps increase its host copier's productivity (if the copier possesses a reversing mecha-
nism).
2. Pre-Reversing Mechanism
The machine's pre-reversing mechanism adds to productivity when processing double-sided origi-
nals.
3. Clip-On Feeding Belt Unit
Compared with the exiting models, the machine's feeding belt can be removed much more easily,
facilitating servicing work.
4. Stream Reading of All Sizes
The machine may use stream reading for all sizes (including large size) of originals (for reproduction
ratios between 50% and 150%).

IV . OPERATION
A. Original Set Indicator
The Original Set indicator turns on when an original is placed on the original tray, and flashes when an
original jams.

Figure 1-401
B. Warnings and Actions to Take
Suspect a jam if the Original Set indicator starts to flash while an original is being fed. Perform the
following steps for correction:
1) Remove all originals from the original tray.
2) Open the upper cover, and remove the jam, if any.
3) Open the ADF, and remove the original, if any, from the copyboard.
4) Put the originals in correct order, and set the stack in the ADF.

1. In outline diagrams, represents mechanical drive paths,
and indicates electrical signal paths.
2. Signals in digital circuits are identified as '1' for High and '0' for Low. The
voltage of signals, however depends on the circuit.
Nearly all operations of the machine are contorolled by the CPU; the internal
workings of the CPU are not relevant to the service person's work and, therefore,
are left out of the discussions. By the same token, no repairs are prescribed for the
PCBs at the user's premises; for this reason, PCBs are discussed by means of
block diagrams rather than circuit diagrams.
For the purpose of explanation, discussions are divided into the following: from
sensors to ADF controller PCB input ports; from ADF controller output ports to
loads; and minor control circuits and functions.

CHAPTER 2 OPERATIONS
I . BASIC CONSTRUCTION
A. Electrical Circuitry
The machine's electrical mechanisms are controlled by the ADF controller PCB. The CPU on
the ADF controller PCB interprets input signals from the machine's sensors and the host copier, and
generates signals to drive the motors, solenoids, and other DC loads.
Figure 2-101
B. Communication with the Copier
The machine communicates using IPC communication 2, which enables communication at a
higher speed than the existing IPC methods.
