2 Outline of the Manual
This Service Manual contains basic information needed to service the G3 FAX Board de-
signed for installation to the iR2200/iR2800/iR3300 in the field, conducted for the purpose
of maintaining its product quality and a specific level of performance. For descriptions on
how to use the iR2200/iR2800/iR3300, see the separately prepared Service Manual.
This Service Manual consists of the following chapters:
Chapter 1 Outline: features, specifications, system configura-
tion, list of user modes
Chapter 2 Basic Operation: functional construction, outline of electrical
circuitry, power supply
Chapter 3 Troubleshooting: points to Note for Troubleshooting, upgrad-
ing
Chapter 4 Installation: installation
Chapter 5 Service Mode: using service mode, list of service modes
Chapter 6 Error Code: list of error codes, main causes, list of mea-
sures
Appendix: curcuit diagram
The descriptions are updated from time to time to reflect product improvements, and ma-
jor changes are communicated in the form of Service Information bulletins.
All service persons are expected to familiarize themselves with the contents of this Ser-
vice Manual and Service Information bulletins and acquire a level of knowledge and skill
required to promptly respond to the needs of the field.
REF.
This Service Manual does not provide detailed descriptions on how to use
the Board or detailed information on user reports. See the separately pre-
pared booklet.
The detailed explanations on SSSW/parameters are limited to those used in
association with the Board; for others, see the separately prepared "G3 Fac-
simile Service Data Handbook" (Rev.0; HY8-23A1-000).
As for error codes, full explanations are on those newly added to the Board
or those for which measures specific to the Board are offered; for others,
see the separately prepared "G3 Facsimile Error Code List" (Rev.1; HY8-
23A0-010).

INTRODUCTION
iii
The following rules apply throughout this Service Manual:
1. Each chapter contains sections explaining the purpose of specific functions and the re-
lationship 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 sig-
nal.
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 ma-
chines 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 Ser-
vice Manual and all relevant Service Information bulletins and be able to identify and isolate
faults in the machine.

MPU (IC34)
µPD703107GJ-025-UEN (V850E-MA1) from NEC is an MPU used to control the com-
munications exchanged on the line.
It is equipped with a 256K-byte internal ROM and a 10K-byte internal RAM, and is
driven by 3.3 V.
ASIC (IC46)

ASIC (IC43)
µPD82870GD-001-LML from NEC used for ASIC (chip D) serves to control the bi-direc-
tional, parallel communications of the IEEE1284 cable (interface with the main controller
PCB), to control the chips around the MPU, to process detection of off-hook state, and to
process CI counter operations.
G3 FAX Control DIMM Slot (J11)
The 16M-bit flash ROM DIMM installed to this slot contains a program used to control
communications on an analog telephone line. The DIMM may be upgraded by downloading
using a Service Support Tool or by replacement.
ASIC (IC16)
µPD65882GC-015-8EU from NEC is an ASIC (port IC), and is used to control the NCU
and various ports such as for speakers.
SDRAM (IC6)
The 64M-bit SDRAM serves as memory for coding/decoding of image data for transmis-
sion/reception or as a work area for the MPU.
RESET IC (IC3)
The reset IC is used when resetting the MPU of the Board, as when the power is tuned on
or when the voltage of the power drops.
MODEM IC (IC11)
FM336 from CONEXANT is a modem used for G3 modulation as prescribed by ITU-T
V.17, V.21, V.27ter,V.29, and V.34. At time of reception, the received data from the line is
subjected to G3 demodulation as prescribed by ITU-T V.17, V.21, V.27ter, V.29, and V.34.
OGMIC (IC44)
OGMIC is used to reproduce voice messages.

2.2 Functions of the NCU PCB
2-Line to 4-Line Conversion Circuit
It converts signals from a 2-line telephone line into transmission signals and reception
signals for a 4-line signal line. In addition, it prevents transmission signals from the mo-
dem from invading the reception circuit.
Dial Pulse Generation Circuit
The dial pulse generation circuit generates dial pulses by turning on and off the relay in
the circuit using control signals from the G3 fax control PCB, thereby enabling the fax
board to transmit dial signals using the dial line.
Off-Hook Detection Circuit
It identifies the condition of the telephone or the handset (option) connected to the tele-
phone terminal as being off- or on-hook in relation to the DC current flowing into it.
Circuit Voltage Conversion Circuit
The primary side of the NC board circuit is controlled by means of a line voltage of +48
VDC; the DC component is cut out using a capacitor, thereby converting only the audio
signals in voltages of a model level.

Power Supply Circuit Used to Detect an Extension
To detect the connection of an extension, the Off-hook detection PCB generates a DC
voltage of +48 V to supply to the extension terminal. A transformer is used to separate the
primary side and the secondary side by an electrical means.
All-Day Power Supply Circuit
The main controller circuit generates all-day 5 VB from all-night +3.3 VB. To operate the
FC detection circuit of the G3 fax control PCB at all times, the +5 VB voltage is sent to
the G3 fax control PCB by way of the Off-hook detection PCB.
