This function is used for the purpose of TEL/FAX automatic switching as follows.
(1) If the machine detects a call with a CNG signal indicating an auto send facsimile call, it starts
an automatic document receiving operation.
(2) If machine detects a call without a CNG signal, machine generates the buzzer sounds as a
telephone call. The calling person can hear a “ring back” tone within a predetermined time.
If the operator at the called side does not lift the handset within the predetermined time, the machine
automatically starts a document receiving operation.
Voice conversation will automatically be available through the internal handset by lifting up the
handset while the call buzzer is sounding.
Note: 1: The predetermined time is selectable between 20 or 35 sec.
(Function program No. 10)
2: No ringing signal is sent to the external telephone handset.
3: Choice of message sending level. The level is selectable from 0 to 15 dB in one dB step.
(Technical function No. 23)
4: TEL/FAX mode is available by Technical Function No.9.

3. BRIEF TECHNICAL DESCRIPTION
40055101TH Rev.4 146 /
Process Illustration Description
3.1 Fundamentals of the Electro-Photographic Process
The electro-photographic process involves six sub-processes:
(1) Charging (2) Exposure (3) Development (4) Transfer (5) Fusing (6) Cleaning
Outline of each process is explained below.
The surface of the electro-photographic
Image drum is uniformly charged with
negative charges by applying a negative
voltage to the charge roller.
When the applied DC voltage exceeds a
threshold value, charging of the drum
begins.
Light emitted from the LED head irradiates
the negatively charged surface.
The potential of the irradiated part of the
Image drum surface is raised, so that an
electrostatic latent image associated with
the print image is formed.
Toner is attracted to the exposed part
(high-potential part) of the Image drum at
the contact between the Image drum and
the developing roller, making the electro-
static latent image visible.
At the same time, the residual toner on the
Image drum is attracted to the developing
roller by static electricity.

The recording paper is placed over the
Image drum surface and a positive charge,
opposite in polarity to the toner, is applied
to the reverse side of the paper from the
transfer roller. The toner is attracted by the
positive charge and is transferred to the
paper. The toner charged negative that is
attracted to the Image drum surface is
transferred to the upper side of the record-
ing paper by the positive charge on the
lower side of the paper.
The unfused toner image is fused on the
paper under heat and pressure as it passes
between the heater roller and the back-up
roller.
Residual toner on the Image drum is
attracted to the cleaning roller temporarily
by static electricity on the Image drum
surface.

4. MECHANICAL DISASSEMBLY AND REASSEMBLY
FOR OKIOFFICE44/OKIFAX 4100
This chapter explains the procedures for replacement of assemblies and units in the field.
4.1 General
4.1.1 Precautions for Parts Replacement
(1) Before starting disassembly and reassembly, always pull out the AC plug.
Note: Unplug the AC power cord from the wall outlet first and then from the facsimile.
(2) Do not try to disassemble as long as the facsimile is operating normally.
(3) Do not remove unnecessary parts: Try to keep disassembly to a minimum.
(4) When disassembling, follow the prescribed sequence. Otherwise, parts may be damaged.
(5) Since screws and small parts are likely to be lost, they should temporarily be attached to their original
positions.
(6) When handling items such as printed circuit boards, do not wear gloves that are likely to generate static
electricity.
(7) Using a wrist band connected to the ground will protect semiconductors on printed circuit boards from
damage by the static electricity.
(8) Do not place printed circuit boards directly on the equipment or on the floor.
Board or Part Adjustment
(a) NCU board DIP switches to be placed in the same position as on the removed board.
Refer to Chapter 8.
(b) LED print head When the rank marking of the replaced LED print head (new part) is the same
as that of the used LED print head (old part), you do not always have to set the
LED print head strobe time by the technical function No. 27. (Refer to section
5.1) When the head label of the replaced LED print head (new part) is the same
as that of the used LED print head (old part), you do not always have to set the
LED print head width by the technical function No.28. (Refer to table 2.9.1, TF
No.28)
(Rev.3)

4. MECHANICAL DISASSEMBLY AND REASSEMBLY
FOR OKIFAX 5100 SERIES
This chapter explains the procedures for replacement of assemblies and units in the field.
4.2 General
4.2.1 Precautions for Parts Replacement
(1) Before starting disassembly and reassembly, always turn the AC power switch OFF, and pull out the AC
plug.
Note: Unplug the AC power cord from the wall outlet first and then from the facsimile.
(2) Do not try to disassemble as long as the facsimile is operating normally.
(3) Do not remove unnecessary parts: Try to keep disassembly to a minimum.
(4) When disassembling, follow the prescribed sequence. Otherwise, parts may be damaged.
(5) Since screws and small parts are likely to be lost, they should temporarily be attached to their original
positions.
(6) When handling items such as printed circuit boards, do not wear gloves that are likely to generate static
electricity.
(7) Using a wrist band connected to the ground will protect semiconductors on printed circuit boards from
damage by the static electricity.
(8) Do not place printed circuit boards directly on the equipment or on the floor.
Board or Part Adjustment
(a) NCU board DIP switches to be placed in the same position as on the removed board.
Refer to Chapter 8.
Note: The DIP switches setting is subject to change by PTT parameters.
WN5, DN5 and FN5 board (Except for USA/Canada version)
(b) LED print head When the rank marking of the replaced LED print head (new part) is the same
as that of the used LED print head (old part), you do not always have to set the
LED print head strobe time by the technical function No. 27. (Refer to Chapter
5)

A2.1 Explanation of Signal Flow for OKIOFFICE44/OKIFAX 4100/5000 Series
Note : Regarding the difference of the signal flow between OKIFAX 4100 and OKIFAX 5000 series,
since one-line scanning processing speed of OKIFAX 5000 series is faster in comparison with
OKIOFFICE 44/OKIFAX 4100, to the circuit diagram of OKIFAX 5000 series has been added
the EXSEED (image processing LSI) and SRAM (dark/light level correction data). Otherwise,
the signal flow is almost the same as in OKIOFFICE 44/OKIFAX 4100.
(1) Copy Mode
Copy mode for OKIOFFICE 44/OKIFAX 4100
Figure A2.1.1 shows the picture signal route in local copy mode for OKIOFFICE 44/OKIFAX
4100
One-line picture data is transferred to A/D converter (analog/digital converter) from the
scanning unit (CIS: contact image sensor) as an analog data. After conversion from analog
data to 6-bit digital data by A/D converter, the picture data is sent to DRAM (line memory) via
IOGA by DMA (Direct Memory Access). Then the picture data is sent to IOGA again. Here,
the picture data undergoes various kinds of picture processings (IOGA and CPU), and is
converted to two-level binary data (black and white). The one-line binary data from IOGA is
stored into DRAMs (page memory). When the data for one page has been stored in the
DRAMs, the data is read out from the DRAMs and sent to IOGA. The data is converted into a
serial data by the picture control of IOGA and transferred to the LED print head for printing as
HDATA 0/1. Writing of data into the page memory is also possible during the printing
operation.
Copy mode for OKIFAX 5000 series
Figure A2.2.1 shows the picture signal route in local copy mode for OKIFAX 5000 series
One-line picture data is transferred to A/D converter (analog/digital) via operational amplifier
from the scanning unit (CIS: contact image sensor) as an analog data. After conversion from
analog data to 6-bit digital data by A/D converter, the picture data is sent to EXSEED (image
processing LSI) and SRAM. Here, the picture data undergoes various kinds of picture
processings (EXSEED and SRAM), converted to two-level binary data (black and white) and
then sent to IOGA (scanning control). The one-line binary picture data from IOGA is stored
into DRAM. When the data for one page has been stored in the DRAM, the data is read out
from the DRAM and sent to IOGA. The data is converted into a serial data by the picture
control of IOGA and transferred to the LED print head for printing as HDATA. Writing of
data into the page memory is also possible during the printing operation.
(2) G3 Send Mode
Figure A2.1.2 (For OKIOFFICE 44/OKIFAX 4100)/Figure A2.2.2 (For OKIFAX 5000 series)
show the G3 send picture signal route
In the G3 mode, the data transfer route from the scan unit up to the DRAM is the same as in the
copy mode described in (1).
The picture data for one-line is transferred from DRAM to CPU. The CPU performs the picture
data processing (encode) for this picture data (FILLER, fill bits are inserted etc.) and again stores
into the DRAM. The stored encoded data is output from DRAM to the MODEM under the
control of CPU. After modulation, the picture signal “S” is sent to the NCU board as the trans-
mission data. The transmission data “S” goes through the amplifier and is sent to the telephone
line L1 and L2 via the transformer T1 as high speed signal.
40055101TH Rev.4 370 /
(3) G3 receive Mode
Figure A2.1.3 (For OKIOFFICE 44/OKIFAX 4100)/Figure A2.2.3 (For OKIFAX 5000 series)
show the G3 receive picture signal route
In the G3 mode, the high-speed picture signal arriving from the telephone line at L1 and L2 of
NCU passes through the transformer T1 and the amplifier and is input to the MODEM as “R”
signal. After demodulation by modem, the picture data is sent to CPU. The CPU performs the
picture data processing (decode) for this picture data and stores into the DRAM. Then, the stored
picture data is again written into DRAM (as a page memory) by the picture processing control of
CPU. When the data for one page has been stored in the DRAM/P-SRAM, the data is read out
from the DRAM and sent to IOGA. The picture data is converted into a signal data by the printer
control of IOGA and transferred to the LED print head for printing as HDATA 0/1.
(4) 300bps Send Mode
Figure A2.1.4 (For OKIOFFICE 44/OKIFAX 4100)/Figure A2.2.4 (For OKIFAX 5000 series)
show 300bps send protocol signal route
In G3 communication, this is the route of the procedural control signals (pre-message, post-
message phases etc.) at 300bps.
The protocol send data is read into DRAM in the sequence the contents of varrious data stored in
the FLASH memory area in advance under the control of CPU. The contents of the frame has
been edited on the DRAM by CPU and sent to MODEM via CPU. HDLC (high level data link
control) frame of the data is structured by the modem and converted to serial data in synchrony
with the modem’s DCLK (data clock). After modulation, the protocol signal is output from “S” of
the modem and sent to the telephone line L1 and L2 via the transformer T1 of NCU.
(5) 300bps Receive Mode
Figure A2.1.5 (For OKIOFFICE 44/OKIFAX 4100)/Figure A2.2.5 (For OKIFAX 5000 series)
show 300bps receive protocol signal route.
In G3 communication, this is the route of the procedural control signals (pre-message, post-
message phases etc.) at 300bps.
The 300bps modulated signals received via the telephone line L1 and L2 of the NCU are sent from
pin R to Pin RXA1 of the modem. After demodulation by the modem, the demodulated digital
signals are sent to the CPU via the data bus from the modem. The data is read and decoded by the
CPU and written into the DRAM. The written data is interpreted according to bit assigment of the
binary procedural signals in the ITU recommendations. The successive modes of communication
(for example, line density,encoding scheme, etc.) are determind.
(6) Report Printing
This signal route describes the printing route of character data used to print Activity Report,
Message Confirmation Report, etc.
The report data is read into DRAM in the sequence the contents of data stored in the FLASH
memory in advance under the control of CPU. The contents of data is edited on the DRAM. The
data is read out from the DRAM and sent to IOGA. The data is converted into a serial data by the
picture control of IOGA and transferred to the LED print head for printing as HDATA 0/1.
40055101TH Rev.4 371 /
(7) Memory Transmission
This signal route describes the memory transmission used in broadcast mode, delayed broadcast
mode, etc.
The stored encoded data undergoes buffering, passes through CPU, MODEM and NCU and then
sent out to the telephone line.
(8) Memory Reception
This signal route describes the memory reception used in no-paper mode, no-toner reception,
confidential mode, etc.
The encoded data received by the same route of (3) G3 receive mode undergoes the picture data
processing and stored into memory (DRAM) as such. In case of printing, When the data for one
page has been stored in the memory (DRAM), the data is read out from the memory and sent to
IOGA. The printed data is converted into a serial data by the printer control of IOGA and
transferred to the LED print head for printing as HDATA 0/1.

The heater in the fuser unit is controlled by the thermister, IOGA and CPU to keep the
heater roller surface within a prescribed temperature range. The CPU supervises the status
of PC0 (A/D converter input section) periodically, turning HEATON- N signal on and off
according to CPU of PC0 status to exercise temperature control.
At power on time, the CPU switches the output signal THON from pin 65 (between high
and low states) to check for a blown or shorted thermister according to the status of the
THCHK signal.
A built-in thermostat in the fuser unit prevents the heater from being overheated in event of
failures in the thermister, or temperature control circuit, etc.
Figure A3.1.16 shows the fuser unit temperature control.
Note: Heater control
Temperature of the heater at the time of printing is 150 ˚C to 180 ˚C. This tempera-
ture is maintained by controlling the on and off operation of heater according to the
input of the thermister converted into analogue-digital (A/D) values by the CPU.

2) Fuser unit temperature control
The heater in the fuser unit is controlled by the thermister, IOGA3 and CPU to keep the
heater roller surface within a prescribed temperature range. The CPU supervises the status
of the port PC0 periodically, turning HEATON signal on and off according to CPU of PC0
(A/D converter input section) status to exercise temperature control.
At power on time, the CPU switches the output signal THON from pin 65 (between high
and low states) to check for a blown or shorted thermister according to the status of the
THCHK signal.
A built-in thermostat in the fuser unit prevents the heater from being overheated in event of
failures in the thermister, or temperature control circuit, etc.
Figure A3.2.18 shows the fuser unit temperature control.
Note: Heater control
Temperature of the heater at the time of printing is 150 ˚C to 180 ˚C. This temperature is
maintained by controlling the on and off operation of heater according to the input of the
thermister converted into analogue-digital (A/D) values by the CPU.

Explanation on Operation
(1) Noise filter circuit
The noise filter consists of L and C to reduce the normal mode noise and common mode noise
incoming from the AC line.
(2) Rectifying and smoothing circuit
The input AC voltage is rectified by diodes D1 to D4 and smoothed by capacitor C6 for DC
voltage supply to the inverter. The rash current at power ON is prevented by TH1.
(3) Switching circuit (RCC type)
This flyback converter (RCC) type switching circuit converts the DC input current to a high
frequency pulse train by switching Q1 ON and OFF. Energy is accumulated in the primary
winding of transformer T1 during the Q1 OFF period, and the accumulated energy is released to
the secondary side in the OFF period for power supply. On/OFF control is performed by gate
voltage control by Q3 via photocoupler PC1 from 5V output.
The overcurrent protection circuit is actuated upon rise in the Q3 base voltage through ZD2 when
the voltage of the bias winding as positive feedback rises due to the rise in the load current. When
a voltage exceeding the zenor voltage of ZD4 and ZD5 is input, ZD4 and ZD5 become conductive
to actuate the overvoltage protection circuit.
If the input voltage is excessive, ZD4 and ZD5 are broken down in the short mode to operate the
overcurrent protection circuit to reduce the output voltage.
The overcurrent protection circuit is automatically reset after the overcurrent state is eliminated.
If ZD4 and ZD5 are broken down by shorting, they should be replaced for recovery from the
overvoltage state.

(4) 5V output circuit
The 5V output is supplied by rectification and smoothing of the output of transformer T1 by
means of diode D8, capacitor C16, choke coil L3 and capacitor C17. Variable resistor VR1 is used
for adjusting the output voltage level.
(5) 8V and 24V output regulator circuits
The -8V output is stabilized by regulator IC2 after rectification and smoothing of transformer T1
output by diode D10 and capacitor C19.
The 24V output is stabilized by Q4, ZD3 and ZD6 after rectification and smoothing of transformer
T1 output by diode D9 and capacitor C22.
(6) Standby power supply circuit (series power supply system)
Since this power supply is provided for saving of power consumption in the standby state, it is
active until the MPON signal rises to the high level. The AC output dropped by low-frequency
transformer T2 is rectified and smoothed by D11 to D14 and C26, which is then stabilized by
regulator IC3 to supply 5 V(S).
When the MPON is set to high, TRC2 is turned ON to activate the switching circuit.
(7) Heater control circuit
The ACON control signal on the secondary side is transmitted to the primary side via PC3 to turn
triac TRC1 ON for AC voltage supply to the heater.

5. General functional description
5-1 General
The power supply unit consists mainly of AC transformer and a power PCB (1VP board for
AC120V/2VP board for AC230V). A block diagram of the power supply unit is shown in Figure
A3.6.1 The power PCB is composed of five main circuits: AC input section, heater control
section, low-voltage section, high-voltage section and protection circuit.
The low-voltage section provides a +5V output by a DC-DC converter and other output voltages
(+30V, +8V and -8V) simply by rectifying and smoothing the respective outputs of the AC
transformer. The high-voltage section (TR1, TR2, DB1, DB2, SB1, SB2, CB and CH) produces a
flyback voltage from 5V by using a drum coil and a high-voltage transformer.
5-2 Circuit description
5-2-1 AC input section
1) AC commercial power is supplied to line filter circuit through the AC inlet, power switch
(SW1) and the fuse (F1). Fuse F1 is used for protecting the heater circuit.
2) The filter circuit consists of L101,R1, C1, C2, C3 and L1. Capacitors C1 and C2 are not
mounted in the power unit for 120VAC input.
3) Fuse F2 is used for protection for the double voltage input in the power supply unit for
120VAC input and will not blow by shorting or opening the secondary circuit. This fuse
F2 is not mounted in the power supply unit for 230VAC input.
5-2-2 Heater control circuit
1) The AC power divided from the AC input section passes through L2 for noise elimination
and is fed to the heater via D1 (operating as a switch) from the power PCB.
2) The on/off operation of D1 is controlled by the operation of photocoupler PC1 whose
operation is controlled by the HEAT-N signal applied to CN3-B7 pin from the control PCB
(M17 board).
3) Resistors R2 and R3 connected on the AC side of PC1 are fuse resistors to protect them-
selves from firing when PC1 turns on in the event of D1 open failure.
5-3 Low-voltage section
5-3-1 +30 V circuit
1) The +30 V circuit provides +30 V output by rectifying the corresponding output of
transformer T1 by a rectifier diode DS1 and smoothing the rectified signal by capacitor C7.
2) Resistor R53 is used to discharge the elecetric charge of C7 when the power switch (SW1)
turned off.
5-3-2 +/- 8 V circuit
1) The +/- 8 V circuit provides +8 V and -8 V outputs by rectifying the corresponding output
of transformer T1 by rectifier diodes D10 and D11 and smoothing the rectified signals by
capacitors C13 and C14.
2) Resistors R22 and R23 are used to discharge the electric charge of C13 and C14 when the
power switch (SW1) is turned off.
40055101TH Rev.4 441 /
5-3-3 +5 V circuit
1) +5 V circuit provides +5 V output by lowering +30 V output by means of DC-DC
concerter circuit.
2) IC1 is a control IC of frequency fixed type (operating at about 30 kHz in present power
supply unit)
3) Q1 is a power transistor, D7 is a flywheel diode, and L3 , C10 and C20 compose a smooth-
ing circuit.
4) The +5 V output is regulated as follows. The rectified +5 V is divided by resistors R83,
R10 and R11 and the resulting voltage is applied to IC1, in which this voltage is regulated
to a constant voltage. Thus, the regulated +5 V output is obtained by controlling IC1.
5-4 Protection circuits
1) The protection circuit includes fuse F3 for +30 V and +5 V overcurrent protection circuit.
2) If an overvoltage is applied to the +5 V circuit, D8, R9 and D6 operate to shortcircuit the
+30 V circuit for half-wave cycle and fuse F3 will blow.
3) F1 will blow only in the event of AC line shortcircuit.
5-5 Cover open circuit
1) The cover open circuit consists of SW2. When the stacker cover is opened, the cover open
microswitch (SW2) on the 1VP/2VP board is turned off to cut the supply of H5V to the
high-voltage power supply circuit. As a result all high-voltage outputs are interruptted. At
the same time, the CVOPN-N signal is sent to the control board to notify it the off state of
the microswitch, and the control board performs the cover open processing.

Increase the resistor value to set quieter receiving level (i.e. higher RLR vallue).
40055101TH Rev.4 480 /
4) Sending Frequency Response Adjustment
The adjustment of the high range frequency response is performed by changing the
capacitance of the capacitor C33. Increase the value of C33 to lower the amplitude of the
high range level. Decrease the value of C33 to raise the amplitude. The adjustnent of the
low range frequency response is performed by changing the capacitance of the capacitors
C35 and C37. Decrease the capacitance of C35 and C37 to lower the amplitude of the low
range level. Increase the capacitance of C35 and C37 to raise the amplitude.
Note: When the sending frequency response is changed, the sending loudness rating
(SLR) value may change. It is required to measure the SLR value again and verify
it.
5) Receiving Frequency Response Adjustment
The adjustment of the low range frequency response is performed by changing the capaci-
tance of the capacitor C26. Increase the capacitance of C26 to raise the amplitude of the
low range level. Decrease the capacitance of C26 to lower the amplitude.
The adjustment of the high range-frequency response is performed by changing the
capacitance of the capacitors C29. Decrease the capacitance of C29 to raise the amplitude
of the high range level. Increase the capacitance of C29 to lower the amplitude of the high
range level.
Note: When the receiving frequency response is changed, the receiving loudness rating
(RLR) value may change. It is required to measure the RLR value again and verify
it.
6) Side-Tone Adjustment
The side-tone adjustment is performed by the C-R networks corresponding to the indi-
vidual countries. For adjusting the side tone, select the corresponding C-R network by the
designated DIP switch and adjust the STMR value to the specified value by the values of
capacitors and resistors.
The dip-switch set to ON corresponds to the country as shown in the table.
Note: When the C-R network is changed for the side tone adjustment, the receiving
loudness rating (RLR) value may change. It is required to measure the RLR value
again and verify it.
7) DC V-I Characteristics
The DC V-I characteristics at the time of the line supplement is performed by diodes D10,
D11 and SW4-5, and can be selected from two types by setting of dip-switch 4-5. In case
SW4-5 is set to ON, since D10, and D11 are short-circuited, V/I value is lowered. In case
SW4-5 is set to OFF, V/I value is raised.

8) Return Loss Adjustment
The return loss adjustment is performed by the installed C-R networks corresponding to the
individual country. For adjusting the return loss, select the corresponding C-R network by
the designated DIP switch and adjust the return loss by changing the values of capacitors
and resistors.
The dip-switch set to ON corresponds to the country as shown in the table.

9) AGC (automatic gain control)
AGC is a function for adjusting the sending and receiving levels automatically in accor-
dance with the line current values, so that the optimal communication level is automatically
set. The circuit section to determine the AGC characteristics is formed by resistors R41
and R43 connected to the AGC terminal of the speech IC. The AGC gain is high when the
resistor values are small, and the AGC gain is low when the resistor values are large.
10) Pulse Dialling
Changing the make-and-break ratio is determined by the dip-switch SW4-1 and 2.
Setting SW4-1 to ON and SW4-2 to OFF corresponds to a 33% make ratio.
Setting SW4-1 to OFF and SW4-2 to ON corresponds to a 40% make ratio.
11) MF dialling
The MF signal sending level is adjusted by the selection of resistors and capacitors
allocated for the individual countries by the dip-switch setting.
The dip-switch set to ON corresponds to the country as shown in the table below.
Country Dip-switch Symbol
UK SW2-1 C31, R38

-6 dBm/-8 dBm
-9 dBm/-11 dBm
-9 dBm/-11 dBm
Increase the resistor value to lower the MF signal sending level, and decrease the resistor
value to raise the sending level. The difference between the high and low groups of the
MF signal is performed by changing the capacitance of the capacitor. The allowable level
difference between the high and low groups is (2±1) dB.
12) Manual Pad
The manual pad is used as a countermeasure by the ON setting of SW3-8 when howling is
occurs because of line conditions. (normally set to OFF)

3-4 TEL-W2D circuit diagram
TEL-W2D board is for the Germany version only.
1) Speech IC
General functions of the speech IC are as follows:
Basic speech functions included.
Separate receive pre-amplifier with signal output terminal
Separate receive power amplifier input terminal, cause it is possible to mixing input.
Balanced input for microphone input to provide immunity to common mode noise.
MF pre-amplifier input terminal is possible to mixing input.
Dial pulse waveform improvement circuit included.
Manual pad function included.
The transmit, receive, and DTMF amplifiers are provided with AGC in accodance with
the line circuit.
2) Sending Level Adjustment
The sending level can be adjusted by resistor R55 connected in parallel with the section in
front of the transmitter. Increase the resistor value to lower the sending level, and decrease
the value to raise the level.
3) Receiving Level Adjustment
The receiving level is determined by the resistor value of R35. Decrease the resistor value
of R35 to lower the receiving level, and increase it to raise the level.
4) Frequency Response Adjustment
The high range frequency response of the transmitter is determined by the capacitance of
C61. Increase the capacitance of C61 to lower the high range level, and decrease the
capacitance to raise the high range level. The low range frequency response is determined
by the capacitance of C36 and C37. Increase the capacitance of those capacitors to raise
the low range level, and decrease the capacitance to lower the level. When the capacitance
of C36 and C37 are changed, both capacitors should have the same value.
The high range frequency response of the receiver is determined by the capacitance of C29.
Increase the capacitance of C29 to lower the high range level, and lower the capacitance to
raise the level. The low-range frequency response is determined by the capacitance of C26.
Increase the capacitance to raise the low-range level, and lower the capacitance to decrease
the low-range level.
5) Side-Tone Adjustment
The side-tone level is determined by the values of R19, R22 and C16.
Note: Changing the side tone level setting affects the sending and receiving levels, the
verification and readjustment of the sending and receiving levels, and the verifica-
tion and the readjustment of the side tone level are required.
6) DC V-I (voltage-versus-current) Characteristics Adjustment
The DC V-I characteristics can be changed by mounting or not mounting D10 and D11.
When D10 and D11 are mounted the DC V/I value is raised. When these diodes are deleted
the DC V/I value is lowered. R202 is a 0 resistor, which is mounted when D10 and D11
are not being installed.
40055101TH Rev.4 485 /
7) Return Loss
The circuit section which determines the return loss is formed by R26, R29 and C21.
8) AGC (automatic gain control)
The gain of the AGC is determined by the resistor value of R41. To lower the AGC gain,
raise the resistor value of R41. To raise the gain, decrease the resistor value.
9) Charge Pulse Elimination Characteristics
The Germany network sends 16kHz pulses for charging to the terminal while the terminal
is connected to the line. The terminal should not cause any mulfunction for the communi-
cation by the charge pulses. In TEL-W2D PCB a parallel oscillation filter is formed by L3,
C305/L2 and C301 which eliminates the charge pulses.
10) Manual Pad
The sending/receiving levels are lowered by 6dB when SW6-1 is set to ON. Use the
setting as a countermeasure when howling is generated because of line conditions (nor-
mally set to OFF).

B1.1 Electro-Photographic Processor
The electro-photographic processor prints out the image data to be sent from the main control board on sheets
of paper. Figure B1-1 shows the layout drawing of the electro-photographic processor.
(1) Image drum unit
The image drum unit makes a toner adhere to the formed electrostatic latent image with static electricity.
This electrostatic latent image is formed by the lights irradiated from LED heads.
(2) Electromagnetic clutch
The electromagnetic clutch controls the rotation of the hopping roller according to signals from the control
block.

(4) LED head
The shift and latch registers receive image data from the main control board for each dot line. 2,560 or
2,496 LEDs are driven to radiate the image drum.
(5) Heat Assy
The heat Assy consists of a heater, a heat roller, a thermistor, and a thermostat.
The power supply unit supplies AC voltage to the heater according to the HEATON signal from the main
control board to heat the heat roller. The main control board monitors the heat roller temperature via the
thermistor and keeps the temperature constant by turning on/off the heater AC voltage supply.
If the heat roller temperature rises abnormally, the thermostat of the heater voltage supply circuit functions
to forcibly suspend the AC voltage supply.
(3) Pulse motor (Main)
This pulse motor of 48 steps/rotation is two-phase excited by the signal from the main control board; it
performs feeding control by switching normal rotation to reverse rotation or vice versa and turning on/off
the electromagnetic clutch. The relationship between the main motor, electromagnetic clutch, regist gear,
drum gear, hopping roller is shown in the table below and on the subsequent pages.

B1.2 Electro-Photographic Process
(1) Electro-photographic process
The electro-photographic process is outlined below.
1 Charging
The surface of the OPC drum is charged negatively and uniformly by applying the DC voltage to the
CH roller.
2 Exposure
Light emitted from the LED head irradiates the negatively charged surface of the OPC drum. The
surface potential of the irradiated surface attenuates to form the electrostatic latent image correspond-
ing to the image signal.
3 Development and residual toner recovery
The negatively charged toner is brought into contact with the OPC drum, adhering to the electrostatic
latent image on the OPC drum by static electricity. This adhesion causes the electrostatic latent image
to change to a visible image.
At the same time, the residual toner on the OPC drum is attracted to the developing roller by static
electricity.
4 Transfer
When paper is placed over the image drum surface, the positive charge which is opposite in polarity
to that of the toner, is applied to the reverse side by the transfer roller. The toner is attracted by the
positive charge and is transferred onto the paper. This results in the transfer of the toner image formed
on the image drum onto the paper.
5 Cleaning
The cleaning roller temporarily attracts the residual toner on the transferred OPC drum with static
electricity, then returns the toner to the OPC drum.
6 Fusing
The transferred unfused toner image is fused to a sheet of paper by applying heat and pressure to the
image.
Figure B1.3 is a flow for the electro-photographic process.

Rotate the pulse motor (main) in the a direction. The planetary gear rotates in the a’ direction, dislocating
its position in the a” direction. This causes the planetary gear to be separated from gear A. The hopping
gear will not rotate. The triple gear and transfer gear rotate via the idle gear to drive the EP unit.

2 The toner applied to the developing roller is thin-coated by the developing blade.
3 A toner adheres to the exposure part of the OPC drum in the contact part between the OPC drum and
developing roller. This causes the electrostatic latent image to be changed to a visible image.
(5) Development
The electrostatic latent image on the surface of the OPC drum is changed to a visible toner image by
applying a toner to it. Development is performed in the contact part between the OPC drum and developing
roller.
1 The sponge roller negatively charges a toner and applies it to the developing roller.
40055101TH Rev.4 515 /
(6) Transfer
The transfer roller is composed of conductive sponge material. This roller is set so that the surface of the
OPC drum and sheets of paper will adhere closely.
A sheet of paper is placed on the surface of the OPC drum and the positive charge opposite to the negative
charge of a toner is applied from the reverse side by the transfer roller.
When a high negative voltage is applied from the power supply to the transfer roller, the positive charge
induced on the surface of the transfer roller moves to the paper side at the contact part between the transfer
roller and the sheet of paper. The positive charge on the lower side of the sheet of paper then causes the
negatively charged toner adhering to the surface of the OPC drum to move to the upper side of the sheet.
This enables transfer to the sheet of paper.

(7) Fusing
The transferred unfused toner image is fused to a sheet of paper because heat and pressure are applied when
it passes between the heat roller and back-up roller.
The Teflon-coated heat roller contains a 400 W heater (Halogen lamp) that heats the heat roller. The
thermistor on the surface of the heat roller keeps the temperature of the heat roller constant. A thermostat
is also installed for safety. If temperature rises abnormally, this thermostat opens to suspend voltage
supply to the heater.
The back-up roller is pressurized to the heat roller by the pressure spring on each side.

APPENDIX B2 DESCRIPTIONS OF PRINT OPERATION (OKIFAX 5000 SERIES)
B2.1 Mechanical Components
1) EP drum cartridge
The EP (image) cartridge consists of an EP (image) drum, a charger, and a developer. The
cartridge forms a toner image on the drum, using an electrostatic latent image formed by the LED
print head.
2) Resist motor
This resist motor is a pulse motor of 48 steps/rotation that is two-phase excited by the signal from
the M17 board. It drives the hopping roller and the resist roller via two one-way clutches accord-
ing to the direction of rotation.
3) Drum motor
This drum motor is a pulse motor of 48 steps/rotation that is two-phase excited by the signal from
the M17 board and is the main motor of this mechanism.
4) LED head
Image data for each dot on a line from the M17 board is received by the shift registers and latch
registers. The Letter size LED head are driven to radiate the image data on to the EP (image)
drum.
5) Fuser
The fuser consists of a heater, a heat roller, a thermister and a thermostat.
An AC voltage from the power supply board (1VP/2VP) is applied to the heater under the control
of the HEAT-N signal from the M17 board. This AC voltage heats the heater. The M17 board
supervises the heat roller temperature via the thermistor, and regulates the heater roller at a
predetermined temperature (about 185 ˚C for OKIFAX 5000 series) by connecting or disconnect-
ing the AC voltage supply to the heater.
If the heater roller temperature rises abnormally, the thermostat of the heater voltage supply circuit
is activated to cut off the AC voltage supply forcibly.

(a) Hopping
1 Hopping turns the resist motor in the "a" direction (in the CW direction) and drives the
hopping roller to advance the paper until the inlet sensor turns on. (In this case, the resist
gear also turns, but the resist roller is prevented from turning by the one-way clutch gear.)
2 After the paper has turned on the inlet sensor, the paper is further advanced by a predeter-
mined length until the paper hits the resist roller. (The skew in the paper can thus be
corrected.)

The charge roller is composed of two layers consisting of a conductive layer and a surface
protective layer that has elasticity, in order to secure a good contact with the EP (image) drum.
When the DC voltage (-1.35 KVDC) applied from the Power Supply Unit exceeds a threshold
value, charging begins. The applied voltage is proportional to charge potential with off set of
approx. -550V.

3) Exposure
Light emitted from the LED head irradiates the EP (image) drum surface with negative charges.
The surface potential of the irradiated part of the EP drum drops, thereby forming an electrostatic
latent image associated with the image signal.
The EP (image) drum is coated with an underlayer (UL), a carrier generation layer (CGL), and
carrier transfer layer (CTL) on the aluminum base. The organic photo conductor layer (OPC),
comprising a CTL and a CGL, is about 20 µm thick.

The EP (image) drum surface is charged to about -750 V by the contact charge of the charge
roller.
When light from the LED head irradiates the EP (image) drum surface, the light energy generates
positive and negative carriers in the CGL. The positive carriers are moved to the CTL by an
electrical field acting on the EP (image) drum. Likewise, the negative carriers flow into the
aluminum layer (ground).
The positive carriers moved to the CTL combine with the negative charges on the EP (image)
drum surface accumulated by the contact charge of the charge roller, lowering the potential on the
EP (image) drum surface. The resultant drop in the potential of the irradiated part of the EP
(image) drum surface forms an electrostatic latent image on it. The irradiated part of the EP
(image) drum surface is kept at about -100 V.

4) Developing
Toner is attracted to the electrostatic latent image on the EP (image) drum surface to convert it
into a visible toner image. Developing takes place at the contact between the EP (image) drum
and the developing roller.
1 As the toner supply roller rotates while rubbing on the developing roller, a friction charge
is generated between the developing roller and the toner, allowing the toner to be attracted
to the developing roller. (The developing roller surface is charges positive and the toner,
negative.)

5) Transfer
The transfer roller is composed of conductive sponge material and is designed to make the EP
(image) drum surface and the paper closely into contact.
Paper is placed over the EP (image) drum surface, and a positive charge, opposite in polarity to
the toner, is applied to the paper from its reverse side.
The application of a high positive voltage (+1 KVDC) from the Power Supply Unit (1VP/2VP
board) to the transfer roller causes the positive charge induced on the transfer roller surface to be
transferred to the paper at the contact between the transfer roller and the paper. As a result, toner
charged negative that is attracted to the EP (image) drum surface is transferred to the upper side of
the paper by the positive charge on the lower side of the paper.

6) Fusing
After the end of the transfer operation, the unfused toner image is fused on the paper under heat
and pressure as it passes between the heater roller and the back-up roller. The heater roller with a
Teflon coating incorporates a 500 W heater (Halogen lamp), which heats the heat roller.
A thermister, which is in contact with the heater roller, regulates the heater roller at a predeter-
mined temperature (about 185 ˚C for OKIFAX 5000 series). A safety thermostat cuts off voltage
supply to the heater by opening the thermostat in the event of abnormal rise in temperature.
The back-up roller is held under a pressure of 2.5 kg by the pressure spring at each side.

7) Cleaning
After the end of the transfer, residual toner on the EP (image) drum is attracted to the cleaning
roller temporarily by static electricity to clean the EP (image) drum surface.
8) Cleaning of rollers
The charge roller, transfer roller and cleaning roller are cleaned in the following cases:
In warning up at power-on time
In warning up after the cover is opened and closed
When the number of accumulated sheets is 10 or more and the printout operation ends
Changes in bias voltage applied to each roller move adhesive toner from the roller to the EP
(image) drum and return it to the developer.

FANON
FANSNS
Max3Sec Max3Sec
Since the fan alarm is not monitored during printing, the fan alarm does not appear from the moment the
printing is started until the completion of printing operation.
In other words, the printing will continue even if the fan alarm occurs during printing.
B2.3.2 Major Trouble Errors
B2.3.2.1 Fuser Error
The fuser error indicates an error in thermister on heater.
In case the fuser error occurs at the time of printing, the heater is turned off soon but the printing contin-
ues of that page.
However, if the error occurs before the write sensor is turned on, the motor stops soon.
B2.3.2.2 Fan Error
The fan error is generated when the FANSNS signal lead goes "1" while the fan is running at full speed.
Operation of the FANSNS signal when the fan is turned on is described below.
40055101TH Rev.4 536 /
B2.3.2.4 2'nd Tray Communication Error
This error is generated if on sending a command to the 2'nd tray is returned no-status (40s) or an unde-
fined status. However, in case there is no status when reset, it will be considered that the 2'nd tray is not
mounted.

B2.3.3.1 Toner Low Detection
Composition
The device consists of the stirring gear which rotates at a constant rate, the stirring bar and the magnet
on the stirring bar. The stirring bar rotates through the link on the protrusion in the stirring gear.
The configuration of stirring bar in the figure below may differ. The principle of toner detection,
however, remains the same.
Operation
Toner Low is detected by monitoring the time interval between the encounter of the magnet set on the
sensor lever and the magnet on the stirring bar.
Stirring Gear Section
Sensor Lever
Toner Sensor
Sensor Lever
Stirring Bar
Stirring Bar
Operation during toner full state
The stirring bar rotates due to interlocking with
the stirring gear.
Even when the magnet on the stirring bar
reaches the maximum height, since the other
side is being dipped in the toner, the stirring bar
is pushed by the stirring gear.
Operation during toner low state
When the stirring bar reaches the maximum
height, since there is no resnstance provided by
the toner on the other side, it falls to the
minimum height due to its own weight. Be-
cause of this, the time interval during which it is
in encounter with the magnet of the sensor lever
becomes long. By monitoring this time interval,
toner low can be detected.

Turning on of the inlet sensors without the hopping operation indicates manual paper feeding for
OKIFAX 2350/2450 (excluding when power is on).
B2.4.2 Cleaning
The image drum needs cleaning since it gets dirty after having printed copies for a number of times.
The two kinds of cleaning are listed in the table below:
Cleaning Type
Cleaning
CH
(charge roller)
cleaning
Function
This cleaning removes the toner whose electric potential is
reversed due to poor electrification, or removes the toner
whose electric potential is insufficient on the image drum
surface.
(Recovery of the toner to developing roller)
Cleaning is performed when the
number of prints exceed 10 sheets
or the one-job operation ends.
(At the end of communication or
copy operations)
This cleaning removes the residual toner on the charging
roller surface. The toner is removed by moving to the
recording paper from charging roller and image drum.

2. MECHANISM DESCRIPTION
2.1 General Mechanism
The Second Paper Feeder feeds the paper into the facsimile by receiving the signal from the facsimile, which
drives the pulse motor inside the Second Paper Feeder, and this motion is transmitted to rotate the one-way
clutch of the hopping frame assembly. The paper is delivered from the hopper into the facsimile through the
turning of the hopping roller and feed roller.
Once delivered into the facsimile, the paper is then controlled and fed through by pulse motor (registration)
of the facsimile.
2.2 Hopper Mechanism
The hopper automatically feeds the facsimile with the paper being set, single sheet at a time. When the paper
is loaded in the paper cassette, it is then transported by the pulse motor, carrying forward only a single sheet
caught by the separation rubber at a time.

3. PARTS REPLACEMENT
This section covers the procedures for the disassembly, reassembly and installations in the field.
This section describes the disassembly procedures, and for reassembly procedures, basically proceed with the
disassembly procedures in the reverse order.
3.1 Precautions Concerning Parts Replacement
(1) Parts replacements must be carried out, by first turning the facsimile power switch off “O” and removing
the facsimile from the Second Paper Feeder.
(2) Do not disassemble the Second Paper Feeder if it is operating normally.
(3) Establish the extent of disassembly suitable for the purpose of the procedure, and do not disassemble any
more than necessary.
(4) Only specified service tools may be used.
(5) Disassembly must be carried out according to the prescribed procedures. Parts may be damaged if such
procedures are not followed.
(6) Small parts such as screws and collars can easily be lost, therefore these parts should be temporarily fixed
in the original location.
(7) When handling printed circuit boards, do not use any glove which may generate static electricity.
(8) Do not place the printed circuit boards directly on the equipment or floor.
