ABOUT LEAD FREE SOLDER (PbF: Pb free)
Note:
In the information below, Pb, the symbol for lead in the periodic table of elements, will refer to standard solder or solder that
contains lead.
We will use PbF solder when discussing the lead free solder used in our manufacturing process which is made from Tin, (Sn),
Silver, (Ag), and Copper, (Cu).
This model, and others like it, manufactured using lead free solder will have PbF stamped on the PCB. For service and repair
work we suggest using the same type of solder although, with some precautions, standard Pb solder can also be used.
Caution
• PbF solder has a melting point that is 50° ~ 70° F, (30° ~ 40°C) higher than Pb solder. Please use a soldering iron with
temperature control and adjust it to 700° ± 20° F, (370° ± 10°C). In case of using high temperature soldering iron, please
be careful not to heat too long.
• PbF solder will tend to splash if it is heated much higher than its melting point, approximately 1100°F, (600°C).
• If you must use Pb solder on a PCB manufactured using PbF solder, remove as much of the original PbF solder as possible
and be sure that any remaining is melted prior to applying the Pb solder.
• When applying PbF solder to double layered boards, please check the component side for excess which may flow onto the
opposite side (See figure, below).
1.1.1.
SUGGESTED PBF SOLDER
There are several types of PbF solder available commercially. While this product is manufactured using Tin, Silver, and Copper,
(Sn+Ag+Cu), you can also use Tin and Copper, (Sn+Cu), or Tin, Zinc, and Bismuth, (Sn+Zn+Bi). Please check the manufacturer’s specific instructions for the melting points of their products and any precautions for using their product with other
materials.
The following lead free (PbF) solder wire sizes are recommended for service of this product: 0.3mm, 0.6mm and 1.0mm.

REMOTE PROGRAMMING
If, after the call is connected, the customer describes the situation and it is determined that the problem can be corrected by
making parameter changes, this function makes it possible to change parameters such as the user code and service code from
another fax (using DTMF tones). Therefore, travel to the customer´s location is not required. However, it is not possible to
change all the parameters remotely (PROGRAM MODE TABLE(P.69)). The function used to accomplish this is remote
programming.
First, in order to check the current status of the service code parameter, print out the setup list (code: 991) and the service list
(code: 999) from the customer´s fax machine.
Based on this, the parameters for the desired codes can be changed.
The procedure for changing and listing parameters is described on ENTERING THE REMOTE PROGRAMMING MODE AND
CHANGING SERVICE CODES(P.68). Also, before exiting the remote programming mode, it is advisable to obtain a new list to
confirm that the changes were made correctly.
Hint:
Since the connected telephone is in use during the remote programming mode, it may be helpful to ask the customer to switch
to the speakerphone. This frees the customer from the need to remain right next to the fax while you are making parameter
settings. When finished, inform the customer. Also note that in very noisy locations where the DTMF tones are not audible, the
remote programming function will not work.

TROUBLESHOOTING DETAILS
OUT LINE
Troubleshooting is for recovering quality and reliability by determining the broken component and replacing, adjusting or cleaning
it as required. First, determine the problem then decide the troubleshooting method. If you have difficulty finding the broken part,
determine which board is broken. (For example: the Digital PCB, Analog PCB, etc.) The claim tag from a customer or dealer may
use different expressions for the same problem, as they are not a technician or engineer. Using your experience, test the problem
area corresponding to the claim. Also, returns from a customer or dealer often have a claim tag. For these cases as well, you need
to determine the problem. Test the unit using the simple check list on SIMPLE CHECK LIST(P.78). Difficult problems may be hard
to determine, so repeated testing is necessary.

INITIALIZATION
There are two types of initialization, one is the short initialization (about 3 seconds) and the other is the long initialization (about
10 seconds). The short initialization makes the unit enter the standby mode. The long initialization makes the unit enter the
standby mode after cleaning or detecting the rest of toner.

CALL SERVICE TROUBLESHOOTING GUIDE
Call Service related error is most frequent.
Call Service 1 ----- Polygon doesn’t rotate......... Refer to LSU (Laser Scanning Unit) SECTION (P.173).
• First, listen to the sound. If rotation sound isn´t heard, check 24V line, POLON signal and POLCLK signal. If even a little of
sound is heard, check XREADY signal.
Call Service 2 ----- Laser isn´t output.......... Refer to LSU (Laser Scanning Unit) SECTION (P.173)
• This can be judged only by referring to signal. Check 5V line, XHSYNC, SPC, VIDEO, LDON.
Call Service 3 ----- Detection of fixing temperature.......... Refer to HEAT LAMP CONTROL CIRCUIT (P.188)
• *Service mode *655 tells the detection number and 3 latest temperatures of the thermistor. The cause distinction code of
the Call Service 3 and the thermistor temperature is displayed. Maximum 3 latest temperatures are displayed showing the
newest on the left. [AABB CCDD EEFF] AA, CC and EE show the cause distinction code and BB, DD and FF show their
temperature.
Cause distinction code
00: means that CALL SERVICE 3 has not been appeared.
01: means that it did not reach 56°C within 22 seconds since the heater was turned ON.
03: means that it did not reach the secondary stabilizing temperature (160°C) within 35 seconds from 56°C.
04: means that it became T2-40deg (120°C or below) after T2; the secondary stabilizing temperature (160°C). (The heater
has burnt out.)
05: means that it became over 220°C.
06: means that during printing the SHORT of the thermistor (AD: 01h or below) was detected.
07: means that the thermistor´s SHORT (AD:00h) and OPEN (AD: F9h or over) were detected.
Call Service 4 ----- Rotation of Fan.......... Refer to FAN MOTOR SECTION (P.170)
• Connector isn’t inserted firmly, dust is caught in and the fan is broken.
* As for Call Services 1, 2 and 4, turn the power OFF then ON to restart.
<Note>
Once “CALL SERVICE3” is displayed, the unit does not disappear until the Factory Setup or Service Function #529 is executed.
Therefore Service Function #529 should be executed before the confirmation, and #529 should be done after the countermeasure.
83
KX-FL612CX / KX-FL612CX-S

The temperature is monitored with the thermistor inside the fuser and detected with the voltage input into IC 606-4pin.
*When Call Service 3 is occurred, the cause can be distinguished.
Refer to page 80 for details.
86
KX-FL612CX / KX-FL612CX-S
6.5.6.4.
CALL SERVICE 4
"CALL SERVICE 4" means that the FAN does not run or the running of the FAN cannot be detected normally.
The running of the FAN is detected by IC 605-91pin. "CALL SERVICE 4" is displayed when it detects NG five times continuously.
After repairing, copy five times.If “CALL SERVICE 4 “ is displayed,check again.

For the receiving problem, we have thought of causes other than in the software. Some causes may be when the fax changes
to the memory receiving mode (for example, when out of paper). and the memory becomes full of the unprinted fax data. In this
case, [MEMORY FULL] and its main cause (for example, “OUT OF PAPER”) are displayed on the LCD. Accordingly, by solving
the main problem, [MEMORY FULL] can be canceled and the receiving problem can solved.
Please refer to USER RECOVERABLE ERRORS (P.59) for the above items.

6.5.11. SPECIAL SERVICE JOURNAL REPORTS
Journal 2 and Journal 3 shown below, which are special journals giving the additional detailed information about the latest 35
communications, can be printed by Service Code 881 or 882. Remote printing function for the journal reports (JOURNAL,
JOURNAL 2 and JOURNAL 3) is also available for service technicians. (Refer to PROGRAM MODE TABLE(P.69).) The
JOURNAL report only gives you basic information about a communication, but the other two journal reports provide different
information on the same item (communication).
HOW TO READ JOURNAL REPORTS:
Example:
1. Look at NO. 01 in the JOURNAL. If you want to know about the details about that item, see NO. 01 in the JOURNAL 2 and the
JOURNAL 3. You can get the following information.
* MODE: Fax transmission
* RCV. MODE: TEL
* TX SPEED: 9.6 kbps
* RESOLUTION: standard
* ENCODE: MH
* MAKER CODE: 79
2. Look at NO. 04 in the JOURNAL 2. CNG (0003) indicates that the CNG signal has been received three times since the
purchase date.

6.5.13. ANALOG BOARD SECTION
This chapter provides the testing procedures required for the analog parts. A signal route to be tested is determined depending
upon purposes. For example, the handset TX route begins at the handset microphone and the signal is output to the telephone
line. The signal mainly flowing on this route is analog. You can trace the signal with an oscilloscope. The signal flow on each
route is shown in the Check Sheet here. If you find a specific problem in the unit, for example if you cannot communicate with
the H/S, trace that signal route locally with the following Check Sheet and locate the faulty point.

Measurement Procedure
1. Open the TOP cover.
2. Remove the developing unit, if it is equipped.
3. Open the TOP cover, and turn ON the TOP cover SW.
(Push the TOP cover SW with a sharp-tipped insulator or insert folded paper, etc. to the slit.)
4. The unit enters the service mode when the TOP cover is open, then push *628.
(Don´t push the START button.)
5. Touch the output terminals under test with the high voltage probes.
6. Push the START button.
(This causes to output high voltage from each terminal, so be careful not to touch them. The sound “Pi Pi Pi” warns that the
high voltage is outputting.)
7. When the measurement is finished, push the STOP button.
(The high voltage output is stopped.)
8. Repeat the items No. 5~7 until the measurement is finished.
9. When the measurement is finished, turn OFF the TOP cover SW.

6.5.17.1. KEY COMPONENTS FOR TROUBLESHOOTING
Check the following parts first: F101, D101-D104, C106, Q101, PC101 and IC101.
This comes from our experience with experimental tests. For example: power supply and lightning surge voltage test, withstanding
voltage test, intentional short circuit test, etc.
Caution:
If you find a melted fuse in the unit, do not turn on the power until you locate and repair the faulty parts (except for the fuse);
otherwise the fuse will melt again and you cannot pinpoint the faulty point.
In most cases, the symptom is that nothing is output. It is more likely that the fault is in the primary side rather than the secondary
side. Check the primary side first.

6.5.17.3. BROKEN PARTS REPAIR DETAILS
(D101~D104)
Check for a short-circuit in terminal 4. If D101~D104 is short-circuit, F101 will melt (open).
In this case, replace all of the parts (D101~D104, F101).
(Q101)
The worst case of Q101 is a short-circuit between the Drain and Gate because damage expands to the peripheral circuit of Q101.
This is due to a very high voltage through the Gate circuit which is composed of R109 and IC101.
You should change all of the parts listed as follows.
F101, Q101, R109, IC101
(D201)
If D201 is broken, the oscillation circuit in the power supply cannot operate. Check it with an electric tester.

RTC BACKUP CIRCUIT
1. Function
This unit has a lithium battery (BAT600) which works for the Real Time Clock IC (RTC: inside IC606).
The RTC continues to work, backed up by a lithium battery even when the power switch is OFF.
2. RTC Inside (IC606) Backup Circuit Operation
When the power switch is turned ON, power is supplied to the RTC (inside IC606). At this time, the voltage at pin 10 of the
IC606 is +3.3V. When the power switch is turned OFF, the BAT600 supplies power to RTC through D602. The voltage at pin
10 of IC606 is about +2.5V. When the power switch is OFF and the voltage of +3.3V decreases, pin 10 of RTC (IC606)
becomes roughly the same voltage as the battery voltage. RTC goes into the backup mode, in which the power consumption
is lower.
156
KX-FL612CX / KX-FL612CX-S
7.3.3.
MODEM CIRCUIT OPERATION
The modem (IC600) has all the hardware satisfying the CCITT standards mentioned previously.
When the ASIC IC606 (114) is brought to a low level, the modem (IC600) is chip-selected and the resistors inside IC are selected
by the select signals from ASIC (IC606) ADR0-ADR4(pin 84~88). Commands are written through the data bus, and all processing
is controlled by the ASIC (IC606) according to CCITT procedures. Here, the INT signal dispatched from IRQ (pin 108 of IC600) to
the ASIC (IC606) implements post processing.
This modem (IC600) has an automatic application equalizer. With training signal 1 or 2 at the time of G3 reception, it can
automatically establish the optimum equalizer. The modem (IC600) operates using the 32.256MHz clock (X600).
1. Facsimile Transmission/DTMF Line Send
The digital image data on the data bus is modulated in the modem (IC600), and sent from pin 69 via modem IC600, Analog gate
array IC207(24→22), amplifier IC204(6→7) and the NCU section to the telephone line.
Refer to CHECK SHEET(P.128).
2. Facsimile Reception
The analog image data which is received from the telephone line passes through the NCU section and enters pin 60 of the
modem (IC600). The signals that enter pin 60 of the modem (IC600) are demodulated in the board to digital image signals, then
placed on the data bus.
In this case, the image signals from the telephone line are transmitted serially. Hence, they are placed on the bus in 8 bit units.
Here, the internal equalizer circuit reduces the image signals to a long-distance receiving level.
This is designed to correct the characteristics of the frequency band centered around 3 kHz and maintain a constant receiving
sensitivity.
It can be set in the service mode.
Refer to CHECK SHEET(P.128).
3. DTMF Transmission (Monitor tone)
The DTMF signal generated in the modem (IC600) is output from pin 69, and the NCU section to the telephone line the same
as facsimile transmission signals.
(DTMF Monitor Tone)
Refer to CHECK SHEET(P.128).
4. Busy/Dial Tone Detection
The path is the same as FAX receiving. When it is detected, the carrier detect bit of the resistor in the modem (IC600) becomes
1, and this status is monitored by ASIC (IC606).
5. Call Tone Transmission
This is the call signal which is generated the ASIC (IC606) and sent to the speaker.

TEL LINE→PC205 (1, 2 - 4)→IC605 (6)
7.4.4.
CALLING LINE IDENTIFICATION CIRCUIT
1. Function
This unit is compatible with the Caller ID service offered by your local telephone company. To use this feature, you must
subscribe to a Caller ID service. The data for the caller ID from the telephone exchange is sent during the interval between the
first and second rings of the bell signal. The data from the telephone exchange is a modem signal which is modulated in an FSK
(Frequency Shift Keying) format. Data “0” is a 1200 Hz sine wave, and data 1 a 2200 Hz sine wave.
There are two type of the message format which can be received: i.e.the single data message format and multiple data
message format.
The multiple data format allows to transmit the name and data code information in addition to the time and telephone number
data.
When there is multiple data in the unit, the name or telephone number are displayed.
2. Circuit Operation
FSK signal of the caller ID signal input from TEL LINE is processed with FSK receiver (IC602).
Refer to CHECK SHEET (P.128) for the route of caller ID signal.
161
KX-FL612CX / KX-FL612CX-S
7.4.5.
LINE AMPLIFIER AND SIDE TONE CIRCUIT
1. Circuit Operation
The reception signal output from the line transformer T201 is input to pin (2) of IC204 via C232, R236 and then the signal is
amplified at pin (1) of IC204 and sent to the reception system.
The transmission signal goes through C224, R232 and enters IC204-pin (6), where the signal is amplified. Then, it is output
from pin (7) of IC204 and transmitted to T201 via L230, C237, R244, R243. Without a side tone circuit, the transmission signal
will return to the reception amplifier via R236, C232. When the side tone circuit is active, the signal output from IC204 pin (7)
passes through L230, C237, R241, R233, C233, C225, C223, and R229 and goes into the amplifier IC204 pin (3). This circuit
is used to cancel the transmission return signal.
The TX signal is output to the circuit analog the route from the IC204 7 pin→L230→C237→R244→R243→T201→TEL LINE.
However, if balance is lost in the bridge, a voltage occurs between the IC207 6 pin and 5 pin and a side tone results, because
the balance cannot be maintained completely at all frequencies in the audio range some side tone always occur.
7.4.6.
LOW PASS FILTER AND NOTCH FILTER

CIS CONTROL SECTION
The scanning block of this device consists of a control circuit and a contact image sensor made up of a celfoc lens array, an LED,
a light guide, and photoelectric conversion elements.
When an original document is inserted and the start button pressed, pin 15 of IC605 goes to a high level and the transistor Q618
turns on.This applies voltage to the LED to light it. The contact image sensor is driven by each of the FTG-F1 signals output from
IC606, and the original image illuminated by the LED undergoes photoelectric conversion to output an analog image signal (SIG).
The analog image signal is input to the system ASIC on AIN1 (pin 3 of IC606) and converted into 8-bit data by the A/D converter
inside IC606. Then this signal undergoes digital processing in order to obtain a high-quality image.

7.11.9. Detecting New Drum Units
Purpose
To investigate the actual number of printed papers with the drum units
(Investigating how the returned sets´ drum units were used)
Method
Whether the drum unit is new or old should be judged by detecting the turn delay of Mixing Paddle (Toner detection sensor).
• When shipping the drum unit, the mixing paddle gear is set to the position that has the space of more than one turn (max.
600).
• After the main motor starts, when the toner detection signal is not varied within the fixed time (max. 4.5 sec), the drum unit
is found new.

7.11.10. TONER SENSOR.... “TONER EMPTY”, “TONER LOW”, “CHANGE DRUM”
The Sensor detects whether or not the Drum unit and the toner are present.
When there is not Drum unit, Hall IC (IC60) turns off, and the input signal of IC605-7 pin (Digital P.C.B) becomes a High level
over 9s. When the Developer unit is set, Hall IC (IC60) turns ON/OFF. If the time of IC605-7 pin´s Low level is under 600ms,
there is enough toner in Developer unit, if not, toner is near empty.
Toner Sensor
The rest of toner is detected by the move speed of the magnet put on the pendulum of Mixing Paddle. The pendulum is pushed
up by the Mixing Paddle, then it falls down by its own weight. The rotation speed of paddle is set slower than the one of
pendulum which falls down by its own weight. When the toner is still left, the pendulum falls and stops on the toner, then pushed
by the paddle, it starts to rotate. When no toner is left, the pendulum falls to the bottom. Consequently the contact time between
the magnet and steel becomes short when toner is left and long with no toner.

7.14.2. CHG-BIAS (Charge BIAS)/DEV(-) BIAS (Developing(-) BIAS)/DEV(+) BIAS
(Developing(+) BIAS) UNIT
When the CHG REM terminal becomes “L”, the transistor Q201 turns ON by IC101, Charge BIAS(-1000V) is output from CHG
OUTPUT, Developing(-) BIAS(-200V) is output from DEV(-) BIAS. After that, when DEV CHG terminal becomes “L”, Q202 turns
ON, and Developing(+) BIAS(+150V) is output from DEV(+) BIAS.
7.14.3. TRA(+) BIAS (Transfer(+) BIAS)/TRA(-) BIAS (Transfer(-) BIAS) UNIT
When the CHG REM terminal is “L” and the TRA CLK terminal is “Open”, Transfer(-) BIAS(-1000V) is output from TRA OUTPUT
the moment Charge BIAS(-1000V) is output from CHG OUTPUT. When 7.8KHz PWM (pulse-width modulation) signal is input to
the TRA CLK terminal, Q103 turns ON by IC101, and TRA(+) CURRENT BIAS according to the PWM signal is output from TRA
OUTPUT. The PWM signal will be turned to a constant voltage by the resistor and the condenser, and input to the IC101. The
IC101 compares this voltage with the feedback voltage from T101 and controls the Q103. As for the transfer current, +25µA is
output when DUTY of the TRA CLK input signal is 0%, or +4µA is output when that is 72%.

[Input Circuit]
The input current goes into the input rectifier circuit through the filter circuit. The filter circuit decreases the noise voltage and
the noise electric field strength.
[Rectifier Circuit]
The input current is rectified by D101~ D104 and charges C106 to make DC voltage. Then it supplies power to the converter
circuit.
[Kick-on voltage circuit]
Bias is applied to the Q101 gate via this circuit when the AC power is turned on and Q101 begins operating.
194
KX-FL612CX / KX-FL612CX-S
The following is an overview of how the power supply unit is controlled.
The control method of this power supply unit is pulse width modulation.
When Q1 is ON, the energy is charged in the transfer primary coil according to E1. When Q1 is OFF, the energy is output from
the secondary transfer as follows.
L → D1 → Load → L
Then the power is supplied to the Load. When Q1 is ON, power is not output from the secondary side. The output voltage is fed
back in the control IC according to the error amp rectifier. Then depending on how TON is controlled, stabilization occurs. Also,
when the current load becomes too large, in order to decrease the voltage output, the increase in is controlled and the output
voltage is stabilized.
Therefore, basically the timing: Ton/Toff of Q1 controls the output voltage.
195
KX-FL612CX / KX-FL612CX-S
[Surge Absorber Circuit]
This circuit is for absorbing surge voltage generated by the transformer.
[Control Circuit and Detecting Circuit]
The control circuit amplifies the output with increased voltage detected in the error detecting circuit. Then it drives the main
transistor.
In this power supply, the duty ratio is defined by changing the ON period of the main transistor.
This is shown as follows.
When the output voltage of the 24V circuit increases, the current of the photo coupler PC101 increases, the pulse width of the
output control IC becomes narrower and the ON period of Q101 becomes shorter.
[Over Current Limiter (O.C.L)]
The highest drain current (Q101) is limited by a limiter circuit (IC101) of 24V. The 24V output is limited by this circuit.
[Over Voltage Circuit]
If the 24V output increases because the error detecting circuit or control circuit is broken, IC101 will recognize this signal and
output becomes 0V.

CHARGING
Charging is the stage that keeps the surface of the sensitive drum a fixed electric potential. The sensitive drum is the Organic Photo
Conductor (OPC), which is a electric conductive cylinder whose surface is covered with the Charge Generation Layer (CGL) and
Charge Transfer Layer (CTL).
When the charging bias (DC -1.0 KV) is added and the minus charge is supplied to the charge brush while charging, the whole
surface potential of the drum is -600V.
Charging Part
197
KX-FL612CX / KX-FL612CX-S
8.1.3.
EXPOSING
When the drum which is charged with the fixed electric charge is irradiated by the laser beam, the plus charge and minus charge
are generated at the Charge Generation Layer. Passing through the Charge Transfer Layer which conducts the plus charge, the
minus-charged drum´s surface is neutralized to be skipped. Then the minus charge goes to the ground from the electric conductive
cylinder. Consequently the charge of the part which is not exposed remains as it is, and the electric potential of the scanned part
changes.
At that time an invisible image is created on the drum.

DEVELOPING AND TRANSCRIPTION
The developing is the stage that the OPC drum with an invisible image is changed to visible by the toner. The developer consists
of mixing paddle, toner supply roller, developing roller, developing blade and OPC drum. The bias voltage is added to the
developing roller (DC -200V) and toner supply roller (DC -200V). Firstly the toner is mixed up in the mixing paddle and minuscharged by triboelectricity, then led to the toner supply roller. Secondly the potential difference causes to send the toner to the
developing roller from the toner supply roller. The supplied toner to the developing roller is kept to a certain layer thickness by the
developing blade and also it is charged by triboelectricity. Consequently the toner is transferred to the surface of the exposed OPC
drum by the potential difference between the developing roller and OPC drum´s surface.
The transfer is the stage that the created image on the OPC drum is transferred to the paper. When the transfer roller is pluscharged with the image, the minus-charged toner particles are gathered on the surface of the drum and transferred to the paper.
Developing and Transcription Part
The values of developing bias and supply bias are different from the ones described in the Service Manual for FL501.
The biases output from the unit of FL501,FLM551 and FLB751(FLB750) have the same voltage. However, the developing device
of FA78X(FA78A) converts the developing and supply biases inside the developing device to improve the image quality.

CLEANING
The toner attached to the surface of the OPC drum is transferred to the paper at the transcription stage, but a part of the toner
remains. The cleaning is the stage that cleans the remain toner after the transcription stage. The remain toner on the drum and the
toner which was attached to the place where the laser beam didn´t scan are gathered to the developing roller to be used again.
When no paper is supplied, the transfer roller is minus-charged to eliminate the minus-charged toner.
Cleaning Part

KX-FL612CX / KX-FL612CX-S
8.1.7.
FIXING
On the process of the transfer, the transferred toner is weakly attached on the paper. Fixing means the process to fix the toner on
the paper permanently. The fixing part melts the toner at the high temperature using the halogen heater. The toner is fixed on the
paper by the heat and pressure through the fixing part with the image. The surface of the heat roller is rosined by Teflon and
lubricated to prevent from attaching the toners. The press roller is made of silicon, and its spring compresses the melted toner.
Fixing Part
The fixing part becomes high temperature, so the thermistor and the thermal fuse are provided.
1. Thermistor
The thermistor touches the heat roller and check the temperature to feed back to the control circuit. The surface temperature
should be kept 160 °C while printing.
2. Thermostat
The thermostat takes the same role with the thermal fuse. The thermostat is located near the heat roller, and it turns OFF the
power when the temperature around the thermostat becomes over 135°C.

8.3.2.
FLAT PACKAGE IC REMOVAL PROCEDURE
1. Put plenty of solder on the IC pins so that the pins can be completely covered.
Note:
If the IC pins are not soldered enough, you may give pressure to the P.C. board when cutting the pins with a cutter.
2. Make a few cuts into the joint (between the IC and its pins) first and then cut off the pins thoroughly.
3. While the solder melts, remove it together with the IC pins.
When you attach a new IC to the board, remove all solder left on the land with some tools like a soldering wire. If some solder is
left at the joint on the board, the new IC will not be attached properly.

DIGITAL BOARD SECTION
When the unit fails to boot up the system, take the troubleshooting procedures very carefully. It may have a serious problem.
The symptom: No response when the power is turned on. (No LCD display, and keys are not accepted.)
The first step is to check the power source. If there is no problem with the power supply unit, the problem may lie in the digital
unit (main board).
As there are many potential causes in this case (ASIC, DRAM, etc.), it may be difficult to specify what you should check first.
If a mistake is made in the order of checks, a normal part may be determined faulty, wasting both time and money.
Although the tendency is to regard the problem as a serious one (IC malfunction, etc.), usually most cases are caused by solder
faults (poor contact due to a tunnel in the solder, signal short circuit due to solder waste).
Note:
1. Electrical continuity may have existed at the factory check, but a faulty contact occurred as a result of vibration, etc., during
transport.
2. Solder waste remaining on the board may get caught under the IC during transport, causing a short circuit.
Before we begin mass production, several hundred trial units are produced at the plant, various tests are applied and any
malfunctions are analyzed. (In past experiences, digital IC (especially, DRAM and ROM) malfunctions are extremely rare after
installation in the product.)
This may be repaired by replacing the IC, (DRAM etc.). However, the real cause may not have been an IC malfunction but a
soldering fault instead.
Soldering faults difficult to detect with the naked eye are common, particularly for ASIC and RA (Resistor Array). But if you have
an oscilloscope, you can easily determine the problem site or IC malfunction by checking the main signal lines.
Even if you don’t have such a measuring instrument, by checking each main signal line and resoldering it, in many cases the
problem will be resolved.
An explanation of the main signals (for booting up the unit) is presented below.
What are the main signals for booting up the unit?
Please refer to DIGITAL BLOCK DIAGRAM (P.150).
The ASIC (IC606) controls all the other digital ICs. When the power is turned on, the ASIC retrieves the operation code stored
in the ROM (IC607), then follows the instructions for controlling each IC. All ICs have some inner registers that are assigned to
a certain address.
It is the address bus by which the ASIC designates the location inside each IC. And the data bus reads or writes the data in
order to transmit the instructions from the ASIC to the ICs.
These signal lines are all controlled by voltages of 3.3V (H) or 0V (L).

MODEM SECTION
8.5.1.
FUNCTION
The unit uses MODEM (IC600) that serves as an interface between the control section for FAX transmission and reception and
the telephone line. During a transmitting operation, the digital image signals are modulated and sent to the telephone line.
During a receiving operation, the analog image signals which are received via the telephone line are demodulated and
converted into digital image signals. The communication format and procedures for FAX communication are standardized by
ITU-T. MODEM has hardware which sends and detects all of the necessary signals for FAX communication.
It can be controlled by writing commands from the ASIC (IC606: inside ASIC).
This MODEM also sends DTMF signals, generates a call tone (from the speaker), and detects a busy tone and dial tones.
Overview of Facsimile Communication Procedures (ITU-T Recommendation):
1. ON CCITT (International Telegraph and Telephone Consultative Committee)
The No. XIV Group of ITU-T, one of the four permanent organizations of the International Telecommunications Union (ITU),
investigates and make recommendations on international standards for facsimiles.
2. Definition of Each Group
• Group I (G1)
Official A-4 size documents without using formats which reduce the band width of a signal are sent over telephone lines.
Determined in 1968.
Transmission for about 6 minutes at a scanning line density of 3.85 lines/mm.
• Group II (G2)
Using reduction technology in the modulation/demodulation format, an A-4 size document is sent at an official scanning line
density of 3.85 lines/mm for about 3 minutes.
Methods to suppress redundancy are not used.
Determined in 1976.
• Group III (G3)
Method of suppressing redundancy in the image signal prior to modulation is used. An A-4 size document is sent within
about one minute.
Determined in 1980.
• Group IV (G4)
Transmission is via the data network. A method is provided for suppressing redundancy in signals prior to transmission, and
error-free reception of transmission is possible.
The scope of these facsimile applications is not limited simply to transmission of written statements. Through symbiotic
linkages with other communication methods, it can be expected to expand to include integrated services.
3. Facsimile Call Time Series
As shown in the following diagram, the facsimile call time series is divided into five phases.
Phase A : Call setting
Call setting can be manual/automatic.
Phase B : Pre-message procedure
Phase B is a pre-processing procedure and sequence for confirming the status of the terminal, transmission route, etc., and for
terminal control. It implements terminal preparation status, determines and displays terminal constants, confirms
synchronization status, etc. and prepares for transmission of facsimile messages.
Phase C : Message transmission
210
KX-FL612CX / KX-FL612CX-S
Phase C is the procedure for the transmitting facsimile messages.
Phase D : Post message procedure
Phase D is the procedure for confirming that the message is completed and received. For continuous transmission, phase B
or phase C is repeated for transmission.
Phase E : Call retrieval
Phase E is the procedure for call retrieval, that is for circuit disconnection.
4. Concerning Transmission Time
Transmission Time
= Control Time
+ Image Transmission Time
+ Hold Time
Transmission time consists of the following.
Control time:
This is time at the start of transmission when the functions at the sending and receiving sides are confirmed, the
transmission mode is established, and transmission and reception are synchronized.
Image transmission time:
This is the time required for the transmission of document contents (image data). In general, this time is recorded in the
catalog, etc.
Hold time:
This is the time required after the document contents have been sent to confirm that the document was actually sent, and
to check for telephone reservations and/or the existence of continuous transmission.

Function
A fixed pattern is transmitted to the receiving side at a speed
(2400 to 14400 bps) designated by DCS, and the receiving side
optimizes the automatic equalizer, etc., according to this signal.
Sends 0 continuously for 1.5 seconds at the same speed as the
training signal.
Notifies the sending side that TCF has been properly received. If
TCF is not properly received, FTT (Failure To Train) X0100010 is
relayed to the sender. The sender then reduces the transmission
speed by one stage and initiates training once again.
Used for reconfirming the receiving side like training 1.
———————
Sends 12 bits (0...01 × 6 times) to the receiver at the same speed
as the image signal and notifies completion of transmission of the
first sheet.

reception, the sender transmits an image signal of the second
sheet.
If there is an operator call from the sender, it is output after RTC.
