1.2. 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 thatcontains 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 repairwork we suggest using the same type of solder.

Caution

· PbF solder has a melting point that is 50° ~ 70° F, (30° ~ 40°C) higher than Pb solder. Please use a soldering iron withtemperature control and adjust it to 700° ± 20° F, (370° ± 10°C). In case of using high temperature soldering iron, pleasebe 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).

· When applying PbF solder to double layered boards, please check the component side for excess which may flow onto theopposite side (See figure, below).

1.2.1. 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 manufac-

turer’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.

1.3. SAFETY PRECAUTIONS 1. Before servicing, unplug the AC power cord to prevent an electric shock.

2. When replacing parts, use only the manufacturer´s recommended components.

3. Check the condition of the power cord. Replace if wear or damage is evident.

4. After servicing, be sure to restore the lead dress, insulation barriers, insulation papers, shields, etc.

5. Before returning the serviced equipment to the customer, be sure to perform the following insulation resistance test to preventthe customer from being exposed to shock hazards.

1.4. INSULATION RESISTANCE TEST 1. Unplug the power cord and short the two prongs of the plug with a jumper wire.

2. Turn on the power switch.

3. Measure the resistance value with an ohmmeter between the jumpered AC plug and each exposed metal cabinet part

(screw heads, control shafts, bottom frame, etc.).

Note: Some exposed parts may be isolated from the chassis by design. These will read infinity.

4. If the measurement is outside the specified limits, there is a possibility of a shock hazard.

1.5. FOR SERVICE TECHNICIANSICs and LSIs are vulnerable to static electricity.

When repairing, the following precautions will help prevent recurring malfunctions.

1. Cover the plastic part´s boxes with aluminum foil.

2. Ground the soldering irons.

3. Use a conductive mat on the worktable.

4. Do not touch the IC or LSI pins with bare fingers.

1.6. BATTERY CAUTIONCAUTION

Danger of explosion if the battery is incorrectly replaced. Replace only with the same or equivalent type recommended by themanufacturer. Dispose of used batteries according to the manufacturer’s Instructions.

The lithium battery is a critical component (typeNo.CR2032). Please observe for the proper polarity and the exact location whenreplacing it and the soldering the replacement litium battery in.

6.5. REMOTE PROGRAMMINGIf, after the call is connected, the customer describes the situation and it is determined that the problem can be corrected bymaking parameter changes, this function makes it possible to change parameters such as the user code and service code fromanother fax (using DTMF tones). Therefore, travel to the customer´s location is not required. However, it is not possible tochange all the parameters remotely (PROGRAM MODE TABLE(P.100)). The function used to accomplish this is remoteprogramming.

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 ANDCHANGING SERVICE CODES(P.99). Also, before exiting the remote programming mode, it is advisable to obtain a new list toconfirm 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 switchto the speakerphone. This frees the customer from the need to remain right next to the fax while you are making parametersettings. When finished, inform the customer. Also note that in very noisy locations where the DTMF tones are not audible, theremote programming function will not work.

6.6. TROUBLESHOOTING DETAILS

6.6.1. OUTLINE

Troubleshooting is for recovering quality and reliability by determining the broken component and replacing, adjusting or cleaningit 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 mayuse different expressions for the same problem, as they are not a technician or engineer. Using your experience, test the problemarea corresponding to the claim. Also, returns from a customer or dealer often have a claim tag. For these cases as well, you needto determine the problem. Test the unit using the simple check list on SIMPLE CHECK LIST(P.110). Difficult problems may be hardto determine, so repeated testing is necessary.

6.6.2. STARTING TROUBLE SHOOTING

Determine the symptom and the troubleshooting method.

Call Service related error is most frequent.

Call Service 1 ----- Polygon doesn’t rotate......... Refer to LSU (Laser Scanning Unit) SECTION (P.235).

· First, listen to the sound. If rotation sound isn´t heard, check 24V line, POLON signal and POLCLK signal. If even a little ofsound is heard, check XREADY signal.

Call Service 2 ----- Laser isn´t output.......... Refer to LSU (Laser Scanning Unit) SECTION (P.235)

· 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.256)

· *Service mode *655 tells the detection number and 3 latest temperatures of the thermistor. The detection point of the CallService 3 and the thermistor temperature is displayed. Maximum 3 latest temperatures are displayed showing the neweston the left. [AABB CCDD EEFF] AA, CC and EE show the detection points and BB, DD and FF show their temperaturedetection points.

00: CALL SERVICE 3 was not occurred.

01: means that the value of AD did not increased by 6 steps or more within 10 sec soon after the heater was turned ON.(thermistor’s open detection)

02: means that it did not reach the first stabilizing temperature (170°C: 5Bh) within 50 seconds.

03: means that it did not reach the second stabilizing temperature (205°C: 3Ch) within 70 seconds after reaching the firststabilizing temperature (170°C: 5Bh).

04: means that it dropped to 165°C: 61h (-40 deg) or below by the temperature control after reaching the second stabilizingtemperature (205°C: 3Ch).

05: means that it did not reach the first stabilizing temperature (170°C: 5Bh) within 30 seconds from detection temperature1 (70°C: D8h).

06: means that it became 235°C: 2Ah or over during printing.

07: means that during printing the short of the thermistor (AD: 00h) was detected.

08: means that the thermistor’s short (AD: 00h) and open (AD: FFh or over) were detected.

<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.

Call Service 4 ----- Rotation of Fan.......... Refer to FAN MOTOR SECTION (P.231)

· Connector isn’t inserted firmly, dust is caught in and the fan is broken.

· Rotation of the Fan can be confirmed by following Test Mode.

For the receiving problem, we have thought of causes other than in the software. Some causes may be when the fax changesto the memory receiving mode (for example, when out of paper). and the memory becomes full of the unprinted fax data. In thiscase, [MEMORY FULL] and its main cause (for example, “OUT OF PAPER”) are displayed on the LCD. Accordingly, by solvingthe main problem, [MEMORY FULL] can be canceled and the receiving problem can solved.

Please refer to USER RECOVERABLE ERRORS (P.84) for the above items.

USB (Universal Serial Bus) block

Description

This is a USB block for data communication with PC.

Two signal lines (D+/D-) are differential signals which work in reverse phase.

VBUS: CN601 1pin

D+: CN601 2pin

D-: CN601 3pin

GND: CN601 4pin

Circuit Diagram

Sequence of normal operation

When USB cable from PC is connected to CN601, Vbus voltage goes up to 5V.

USBPWR becomes about 3V, and IC600 recognizes the connection with PC. Then D+ becomes about 3V: waveform 1

The D+ becomes 0V, then communication between IC 600 and PC is started: waveform 2

When a few seconds elapsed after USB cable was inserted into CN601, the unit enters stand-by mode.

When PC is at Full Speed, waveforms are 3 and 4.

When PC is at Hi-Speed, waveforms are 5 and 6.

6.6.20. POWER SUPPLY BOARD SECTION

6.6.20.1. KEY COMPONENTS FOR TROUBLESHOOTING

Check the following parts first: F1, F2, D10-D13, C5, C55, Q1, PC1 and IC1.

This comes from our experience with experimental test. For example: power supply and lightning surge voltage test, with standingvoltage test, intentional short circuit test, etc.

Caution:

If you find a melted fuse in the unit, do not turn on the power until you located 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 secondaryside. Check the primary side first.

6.6.20.3. BROKEN PARTS REPAIR DETAILS

(D10~D13)

Check for a short-circuit in terminal 4. If D10~D13 is short-circuit, F2 will melt (open).

In this case, replace all of the parts (D10 - D13, F2).

(Q1)

The worst case of Q1 is a short-circuit between the Drain and Gate because damage expands to the peripheral circuit of Q1.

This is due to a very high voltage through the Gate circuit which is composed of R7 and IC1. You should change all of the partslisted as follows. F2, Q1, R7, IC1

(D101)

If D101 is broken, the oscillation circuit in the power supply cannot operate. Check it with an electric tester.

(F151)

If F151 is melted (open), check the 12 Voltage line of the Digital PCB and others.

(F301)

If F301 is melted (open), check the 3.3 Voltage line of the Digital PCB and others.

(F501)

If F501 is melted (open), check the 6 Voltage line of the Digital PCB and others.

7.3.2. RTC (Real Time Clock) BACKUP CIRCUIT

1. Function

This unit has a lithium battery (BAT600) which works for the Real Time Clock IC (RTC: inside IC604).

The RTC continues to work, backed up by a lithium battery even when the power switch is OFF.

2. RTC Inside (IC604) Backup Circuit Operation

When the power switch is turned ON, power is supplied to the RTC (inside IC604). At this time, the voltage at pin 128 of theIC604 is +3.3V. When the power switch is turned OFF, the BAT600 supplies power to RTC through DA600.

When the power switch is OFF and the voltage of +3.3V decreases, pin 128 of RTC (IC604) becomes roughly the same voltageas the battery voltage. RTC goes into the backup mode, in which the power consumption is lower.

211

KX-FLB853RU

7.3.3. MODEM CIRCUIT OPERATION

The modem (IC607) has all the hardware satisfying the CCITT standards mentioned previously.

When the ASIC IC600 is brought to a low level, the modem (IC607) is chip-selected and the registors inside IC are selected by theselect signals from ASIC (IC600) A[0]-A[5]. Commands are written through the data bus, and all processing is controlled by theASIC (IC600) according to CCITT procedures. Here, the INT signal dispatched from IRQ (pin 1 of IC607) to the ASIC (IC606)implements post processing.

This modem (IC607) has an automatic application equalizer. With training signal 1 or 2 at the time of G3 reception, it canautomatically establish the optimum equalizer. The modem (IC607) operates using the 28.224MHz clock (X604).

1. Facsimile Transmission/DTMF Line Send

The digital image data on the data bus is modulated in the modem (IC607), and sent from pin 25, 26 via modem IC607, Analoggate array IC209(24→22), amplifier IC204(6→7) and the NCU section to the telephone line.

Refer to CHECK SHEET(P.161).

2. Facsimile Reception

The analog image data which is received from the telephone line passes through the NCU section and enters pin 29 of themodem (IC607). The signals that enter pin 29 of the modem (IC607) are demodulated in the board to digital image signals, thenplaced 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 receivingsensitivity.

It can be set in the service mode.


3. DTMF Transmission (Monitor tone)

The DTMF signal generated in the modem (IC607) is output from pin 25, 26 and the NCU section to the telephone line the sameas facsimile transmission signals.

(DTMF Monitor Tone)


4. Busy/Dial Tone Detection

The path is the same as FAX receiving. When it is detected, the carrier detect bit of the registor in the modem (IC607) becomes1, and this status is monitored by ASIC (IC600).

5. Call Tone Transmission

This is the call signal which is generated the ASIC (IC604) and sent to the speaker.

7.4.3. BELL DETECTION CIRCUIT


The signal waveform for each point is indicated below. The signal (low level section) input to pin 6 of gate array IC605 on thedigital board is read by ASIC and judged as a bell.

TEL LINE→PC205 (1, 2 - 4)→IC600 (H17)

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 mustsubscribe to a Caller ID service. The data for the caller ID from the telephone exchange is sent during the interval between thefirst 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 datamessage format.

The multiple data format allows to transmit the name and data code information in addition to the time and telephone numberdata.

When there is multiple data in the unit, the name or telephone number are displayed.


FSK signal of the caller ID signal input from TEL LINE is processed with MODEM (IC607).

KX-FLB853RU

7.4.5. LINE AMPLIFIER AND SIDE TONE CIRCUIT


The reception signal output from the line transformer T200 is input to pin (2) of IC204 via C244, R237 and then the signal isamplified at pin (1) of IC204 and sent to the reception system.

The transmission signal goes through C240, R238 and enters IC204-pin (6), where the signal is amplified. Then, it is outputfrom pin (7) of IC204 and transmitted to T200 via, C248, R245. Without a side tone circuit, the transmission signal will returnto the reception amplifier via C234, R229. When the side tone circuit is active, the signal output from IC204 pin (7) passesthrough C236, R241, R233, C234, and R229 and goes into the amplifier IC204 pin (3). This circuit is used to cancel thetransmission return signal.

The TX signal is output to the circuit analog the route from the IC204 7 pin→C248→R245→T200→TEL LINE.

However, if balance is lost in the bridge, a voltage occurs between the IC204 2 pin and 3 pin and a side tone results, becausethe balance cannot be maintained completely at all frequencies in the audio range some side tone always occur.

When an original document is inserted and the start button pressed, pin U4 of IC600 goes to a low level and the transistor Q51turns on. This applies voltage to the CCD. The CCD is driven by each of the SI, CLKS, CCDSW0, CCDRS, CCDCP signals outputfrom IC600, and the original image illuminated by the CCFL undergoes CCD to output an analog image signal (mono: Vout1-2,color: Vout1-3). The analog image signal is input to the AFE on CCDIN0-2 (mono: CCDIN0-1, color: CCDIN0-2) (pin 23, 25, 27 ofIC53) and converted into 16-bit data by the A/D converter inside IC53. Then this signal undergoes digital processing in order toobtain a high-quality image.

If the time of IC604-95pin´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 pushedup by the Mixing Paddle, then it falls down by its own weight. The rotation speed of paddle is set slower than the one ofpendulum which falls down by its own weight. When the toner is still left, the pendulum falls and stops on the toner, then pushedby the paddle, it starts to rotate. When no toner is left, the pendulum falls to the bottom. Consequently the contact time betweenthe magnet and steel becomes short when toner is left and long with no toner.

3.3VOutputCircuit

[Input Circuit]

The input current goes into the input rectifier circuit through the filter circuit. The filter circuit decreases the noise voltage andthe noise electric field strength.

[Rectifier Circuit]

The input circuit is rectified by D10 to D13 and charge C5 and C55 to make DC voltage. Then it supplies power to the convertercircuit.

[Kick-on Voltage Circuit]

Bias is applied to the Q1 gate via this circuit when the AC power is turned on and Q1 begins operating.

262

KX-FLB853RU

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 fromthe 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 fedback 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 outputvoltage is stabilized.

Therefore, basically the timing: Ton/Toff of Q1 controls the output voltage.

263

KX-FLB853RU

[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 maintransistor.

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 PC1 increases, the pulse width of theoutput control IC becomes narrower and the ON period of Q1 becomes shorter.

[Over Current Limiter (O.C.L)]

The highest drain current of Q1 is limited by a limit current function of IC1. The 24V output is limited by this function.

[Over Voltage Circuit]

If the 24V output increases because the error detecting circuit or control circuit is broken, IC1 will recognize this signal andoutput becomes 0V. D104, D275 and D503 also prevent over voltage.

[3.3V Output Circuit]

This circuit is composed of DC-DC converter method.

8 REFERENCE MATERIALS DATA8.1. PRINTING OPERATION PRINCIPLE8.1.1. PROCESS CHART AND PROCESS BIAS

8.1.2. CHARGING

Charging is the stage that keeps the surface of the sensitive drum a fixed electric potential. The sensitive drum is the Organic PhotoConductor (OPC), which is a electric conductive cylinder whose surface is covered with the Charge Generation Transfer Layer(CGTL).

When the charging bias is added and the plus charge is supplied to the opc surface while charging, the whole surface potential ofthe drum is +475V.

Charging Part

265

KX-FLB853RU

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 chargeare generated at the Charge Generation Transfer Layer. Passing through the Charge Generation Transfer Layer which conductsthe minus charge, the plus-charged drum´s surface is neutralized to be skipped. Then the plus charge goes to the ground from theelectric conductive cylinder. Consequently the charge of the part which is not exposed remains as it is, and the electric potentialof the scanned part changes.

At that time an invisible image is created on the drum.

Exposing Part

8.1.4. LASER SCANNING UNIT LOCATIONS

266

KX-FLB853RU

8.1.5. DEVELOPING AND TRANSCRIPTION

The developing is the stage that the OPC drum with an invisible image is changed to visible by the toner. The drum unit consistsof mixing paddle, toner supply roller, developing roller, developing blade, charge wire, grid plate and OPC drum. The bias voltageis added to the developing roller and toner supply roller. Firstly the toner is mixed up in the mixing paddle and plus-charged bytriboelectricity, then led to the toner supply roller. Secondly the potential difference causes to send the toner to the developing rollerfrom the toner supply roller. The supplied toner to the developing roller is kept to a certain layer thickness by the developing bladeand also it is charged by triboelectricity. Consequently the toner is transferred to the surface of the exposed OPC drum by thepotential 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 minus-charged with the image, the plus-charged toner particles are gathered on the surface of the drum and transferred to the paper.

Developing and Transcription Part

KX-FLB853RU

8.1.6. CLEANING OF TRANSFER ROLLER

The toner attached to the surface of the OPC drum is transferred to the paper at the transcription stage, but a part of the tonerremains. The cleaning is the stage that cleans the remain toner after the transcription stage. The remain toner on the drum and thetoner which was attached to the place where the laser beam didn´t scan are gathered to the developing roller to be used again.After paper jam or replacing toner and drum unit, the transfer roller is plus-charged to eliminate the plus-charged toner.

Cleaning Part

268

KX-FLB853RU

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 onthe paper permanently. The fixing part melts the toner at the high temperature using the halogen heater. The toner is fixed on thepaper by the heat and pressure through the fixing part with the image. The surface of the heat roller is rosined by Teflon andlubricated 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 temperatureshould be kept 205°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 thepower when the temperature around the thermostat becomes over 160°C.

Note:

See ABOUT LEAD FREE SOLDER (PbF: Pb free) (P.6).

8.3.2. PROCEDURE

1. Tack the flat pack IC to the PCB by temporarily solderingtwo diagonally opposite pins in the correct positions on thePCB.

Be certain each pin is located over the correct padon the PCB.

2. Apply flux to all of the pins on the IC.

3. Being careful to not unsolder the tack points, slide thesoldering iron along the tips of the pins while feedingenough solder to the tip so that it flows under the pins asthey are heated.

8.3.3. REMOVING SOLDER FROMBETWEEN PINS

1. Add a small amount of solder to the bridged pins.

2. With a hot iron, use a sweeping motion along the flat part ofthe pin to draw the solder from between the adjacent pads.

8.4. DIGITAL BOARD SECTIONWhen 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 digitalunit (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 solderfaults (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., duringtransport.

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 anymalfunctions are analyzed. (In past experiences, digital IC (especially, DRAM and ROM) malfunctions are extremely rare afterinstallation 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 asoldering fault instead.

Soldering faults difficult to detect with the naked eye are common, particularly for ASIC and RA (Resistor Array). But if you havean 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 theproblem 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.203).

The ASIC (IC600) controls all the other digital ICs. When the power is turned on, the ASIC retrieves the operation code storedin the ROM (IC602), then follows the instructions for controlling each IC. All ICs have some inner resistors that are assigned toa 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 inorder 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).

8.5. 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 andthe 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 andconverted into digital image signals. The communication format and procedures for FAX communication are standardized byITU-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 linedensity 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 withinabout 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, anderror-free reception of transmission is possible.

The scope of these facsimile applications is not limited simply to transmission of written statements. Through symbioticlinkages 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 forterminal control. It implements terminal preparation status, determines and displays terminal constants, confirmssynchronization status, etc. and prepares for transmission of facsimile messages.

Phase C : Message transmission

277

KX-FLB853RU

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 Bor 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, thetransmission 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 thecatalog, etc.

Hold time:

This is the time required after the document contents have been sent to confirm that the document was actually sent, andto check for telephone reservations and/or the existence of continuous transmission.

Signal Identification Signal Format FunctionTraining 1 ——————— A fixed pattern is transmitted to the receiving side at a speed

(2400 to 14400 bps) designated by DCS, and the receiving sideoptimizes the automatic equalizer, etc., according to this signal.

TCF(Training Check)

——————— Sends 0 continuously for 1.5 seconds at the same speed as thetraining signal.

CFR(Confirmation to Receive)

X0100001 Notifies the sending side that TCF has been properly received. IfTCF is not properly received, FTT (Failure To Train) X0100010 isrelayed to the sender. The sender then reduces the transmissionspeed by one stage and initiates training once again.

Training 2 ——————— Used for reconfirming the receiving side like training 1.Image Signal Refer to the next page. ———————RTC(Return to Control)

——————— Sends 12 bits (0...01 × 6 times) to the receiver at the same speedas the image signal and notifies completion of transmission of thefirst sheet.

EOP(End of Procedure)

X1110100 End of one communication

MCF(Message Confirmation)

X0110001 End of 1 page reception

DCN(Disconnect)

X1011111 Phase E starts.

MPS(Multi-Page Signal)

X1110010 Completion of transmission of 1 page. If there are still moredocuments to be sent, they are output instead of EOP. After MCFreception, the sender transmits an image signal of the secondsheet.

PRI-EOP(Procedural Interrupt-EOP)

X1111100 If there is an operator call from the sender, it is output after RTC.

PIP(Procedural Interrupt Positive)

X0110101 This is output when an operator call is received.

b. Redundancy Compression Process Coding Mode

This unit uses one-dimensional MH format.
