1 INTRODUCTION 1.1.

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 prevent the customer from being exposed to shock hazards.

1.2.

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.

1.3.

FOR SERVICE TECHNICIANS

ICs 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.

1.4.

BATTERY CAUTION

CAUTION Danger of explosion if the battery is replaced incorrectly. Replace only with the same or equivalent type recommended by the manufacturer. Discard used batteries according to following caution: Disposal of lithium batteries should be performed by permitted, professional disposal firms knowledgeable in state government federal and local hazardous materials and hazardous waste transportation and disposal requirements. A battery continues to have no transportation limitations as long as it is separated to prevent short circuits and packed in strong packaging. Commercial firms that dispose of any quantity of lithium cells should have a mechanism in place to for their ultimate disposition. This is a good practice for all types of commercial or industrial waste. Recommend Type Number: CR2032 (BAT501) Manufactured by MATSUSHITA CR2032 (BAT501) Manufactured by SONY 3

TROUBLESHOOTING DETAILS OUTLINE

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 2.3.3.1 SIMPLE CHECK LIST(P.32). Difficult problems may be hard to determine, so repeated testing is necessary.

THE UNIT CAN COPY, BUT CANNOT TRANSMIT/RECEIVE

CROSS REFERENCE: 2.3.7 ANALOG BOARD SECTION(P.74) 2.5 TEST FUNCTIONS(P.99)

2.3.5.1.5.

THE UNIT CAN COPY, BUT CANNOT EITHER TRANSMIT/RECEIVE LONG DISTANCE OR INTERNATIONL COMMUNICATIONS

The following two causes can be considered for this symptom. Cause 1: The other party is executing automatic dialing, the call has been received by this unit, and the CED or DIS signal response time is too long. (In most cases, this unit detects the CNG signal and can respond to CED or DIS.) (According to the ITU-T standard, the communication procedure is cancelled when there is no response from the other party within 35 sec, so that the other party releases the line.)

50

KX-FP80

(Cause and Countermeasure) As shown in the chart above, the total handshaking time must be reduced, but because of the long distance connection and linking of several stations, the line connection time cannot be reduced. Accordingly, the following countermeasures should be tried. (A)... As the 35 sec. count is started directly after dialing or directly after the START button has been pressed for models with a START button, the other party should be called manually, if possible. Another possibility is entering two pauses at the end of the auto dial number on the transmission side. Then the count start time can be delayed for 2 pauses (about 10 sec.). Cause 2: Erroneous detection because of an echo or an echo canceler.

(Echo/Echo Canceler) The signal from FAX1 reaches FAX2 via stations 1 and 2, but the reflection signal at station 2 also returns via station 1 (echo). As the distance between station 1 and station 2 is far, the echo returns to FAX 1 at a max of 600 msec after transmission. There is a possibility that this signal is detected erroneously as the signal from FAX2. For a normal call, there is also a possibility that the echo of their own voice will make the call difficult to understand. For this reason, each station (station 1 and station 2) attaches echo cancelers (S1 and S2) for international lines or long distance lines. For the echo canceler, the level of the transmission signal from FAX 1 is compared with the level of the reception signal from FAX2. When the transmission signal is larger, S1 is closed while S2 is opened when it is smaller. In other words, for transmission from FAX1, S1 is closed and S2 is open, so that the echo does not return to FAX1. (Causes and Countermeasures) (Cause A) When a training signal is transmitted from FAX1 during the communication procedure at the time of transmission from FAX1 to FAX2, there is a delay until the echo canceler operates. S1 is closed so that a part of the head of the training signal may drop out. Normal reception by FAX2 may not be possible, and transmission may not be started. (Countermeasure A) When the international line mode is ON in the service mode (code No. 521), a dummy signal is attached to the head of the training signal to prevent this problem. As this is normally ON, it is necessary to reconfirm that this has not become OFF. When the international mode is switched OFF, the transmission side will try the training signal three times at each speed (9600BPS, 4800BPS and 2400BPS). If NG, it will drop the speed by one rank (fall-back). When the international mode is switched ON, each speed will be tried only twice. In other words, the slower speed with fewer errors can be accessed more easily. This is done because the line conditions may deteriorate and the picture may be disturbed more easily during communication for international lines or long distance communication, even when the training is OK. The default value is ON as preference is given to clearer pictures rather than speed. (Cause B) The echo canceler operation stops with a 2100Hz signal. (i.e. S1 and S2 become ON). Accordingly, when FAX1 has executed automatic reception, a CED signal is output. If this signal is 2100Hz, S1 and S2 will become ON. Then the echo of the DIS signal output afterwards may be received and FAX1 may execute an erroneous operation, preventing communication from starting. (Countermeasure B) In the service mode, the CED signal frequency is set to 1100 Hz (code No.520), or the time setting between the CED signal and the DIS signal is set from 75 msec to 500 msec in the service mode (code No.593). This is because the echo canceler operation stop mode is canceled by an interval of 250 msec or more. Reduce receiving sensitivity to reduce the effect of RCV echo signal. (Service mode: code No. 598)

51

KX-FP80

(Cause C) This model is FAX1 and the other party is FAX2. For transmission from this model to FAX2, FAX2 executes automatic reception and transmits a CED signal (2100 Hz) followed by a DIS signal. As the echo cancelers stops as described in cause B, the echo of the DIS signal returns to FAX2. On the other hand, this model detects the DIS signal and transmits a DCS signal. In other words, it is possible that the echo of the DIS signal and the DCS signal transmitted from this model reach FAX2 one after the other. FAX2 detects an error and communication does not start. (Countermeasure C) When the international DIS detection setting is set in the service mode (code No.594), this model does not respond to the first DIS signal and returns a DCS signal only for the second DIS signal. In other words, there is an interval of 250 msec between transmission of the first and second DIS signal so that the echo cancelers operation recovers. An echo is not generated for the second DIS signal. Note: When the other FAX does not respond with a DCS signal after DIS signal transmission, the DIS signal is transmitted three times for trial. Summary: Symptom/Countermeasure Table (Long distance and international communication operations) SYMPTOM Does not receive in the automatic mode.

COUNTERMEASURE 1. If possible, manual transmission should be done from the transmission side. 2. If possible, two pauses should be inserted at the end of the auto dial number on the transmission side.

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 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 (2.3.5.2.2 PROGRAM MODE TABLE(P.63)). 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 2.3.5.2.1 ENTERING THE REMOTE PROGRAMMING MODE AND CHANGING SERVICE CODES(P.62). 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.

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 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 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 SRAM, 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 2.3.6.1 DIGITAL BLOCK DIAGRAM (P.66). The ASIC (IC501) controls all the other digital ICs. When the power is turned on, the ASIC retrieves the operation code stored in the ROM (IC502), then follows the instructions for controlling each IC. All ICs have some inner s 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 5V (H) or 0V (L). 65

DIGITAL BLOCK DIAGRAM

You also need to check the signal lines listed here [List 1] when the unit fails to boot up the system. Those signal lines should remain normal. Other signal lines are not directly related to that failure even if they have faults or troubles.

As long as these signals remain normal, once the power is turned on, each IC can repeatedly output 5V (H) and 0V (L). The following shows NG and normal wave patterns.

Normal Wave Patterns

Remarks: When you use an oscilloscope to judge whether a signal to be tested is normal or NG, perform the signal check in exactly the same order as in [List 1]. (If the ASIC fails to access the ROM, the ASIC cannot access SRAM or DRAM normally.) The digital circuit actually operates according to the timing combinations of these signals. If the timing of these signals is even slightly delayed, the circuit will not work. Nor will it if the IC is defective and the output voltage level is not normal although the timing of these signals is accurate enough to meet the specifications. (Make sure that your oscilloscope is calibrated before starting a test.) Therefore, it is imperative to confirm whether each IC outputs the signal at the correct level. (See the I/O Pin No. Diagram.) The signal level should be constantly output at between 5V (H) and 0V (L) as described earlier. Note: Simply check the output level and make sure if the IC repeatedly outputs the signal at between 5V (H) and 0V (L). 68

After the power is turned on, the ASIC initializes and checks each IC. The ROM, SRAM, and modem are checked. If initialization fails for the ICs , the system will not boot up. In this case, please find the cause as follows.

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.

POWER SUPPLY BOARD SECTION 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.

BROKEN PARTS REPAIR DETAILS

(D101, D102, D103, D104) Check for a short-circuit in terminal 4. If D101, D102, D103 and D104 are short-circuits, F101 will melt (open). In this case, replace all of the parts (D101, D102, D103, 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 R128, R109, D106 and IC101. You should change all of the parts listed as follows. F101, Q101, R128, R109, D106, IC101 (D201) If D201 is broken, the oscillation circuit in the power supply cannot operate. Check it with an electric tester.

5 HOW TO REPLACE THE FLAT PACKAGE IC Even if you do not have the special tools (for example, a spot heater) to remove the Flat IC, with some solder (large amount), a soldering iron and a cutter knife, you can easily remove the ICs that have more than 100 pins.

5.1.

PREPARATION

· SOLDER Sparkle Solder 115A-1, 115B-1 OR Almit Solder KR-19, KR-19RMA · Soldering iron Recommended power consumption is between 30 W to 40 W. Temperature of Copper Rod 662 ± 50°F (350 ± 10°C) (An expert may handle a 60~80 W iron, but a beginner might damage the foil by overheating.) · Flux HI115 Specific gravity 0.863 (Original flux should be replaced daily.)

5.2.

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 t (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 t on the board, the new IC will not be attached properly.

RESET CIRCUIT (WATCH DOG TIMER)

The output signal from pin 1 of the voltage detect IC (IC509) is input to the ASIC (IC501) 112 pin. Then the output signal from pin 109 of the ASIC (IC501) resets the ASIC.

1. During a momentary power interruption, a positive reset pulse of 46~51 msec is generated and the system is reset completely.

2. When pin 108 and 109 of IC501 become low level, they will prohibit the SRAM (IC504) from changing data. The SRAM (IC504) will go into the backup mode, when they are backed up by a lithium battery. 3. The watch dog timer, built-in the ASIC (IC501), is initialized by the U about every 1.5 ms. When a watch dog error occurs, pin 113 of the ASIC (IC501) becomes low level. The terminal of the ´WDERR´ signal is connected to the reset line, so the ´WDERR´ signal works as the reset signal.

SRAM AND RTC BACKUP CIRCUIT

1. Function This unit has a lithium battery (BAT501) which works for the SRAM (IC504) and Real Time Clock IC (RTC: inside IC501). The parameters for autodial numbers, the system setup data and others are stored in the SRAM (IC504). The RTC continues to work, backed up by a lithium battery even when the power switch is OFF. 2. SRAM (IC504) Backup Circuit Operation When the power switch is turned ON, power is supplied through pin 12 of IC501 to the SRAM (IC504). At this time, the voltage at pin 28 of the SRAM is 5V. When the power switch is turned OFF, the BAT501 supplies power to the SRAM through J501, R541 and D504. The voltage at pin 28 of the SRAM is about +2.5V. When the power switch is OFF and the voltage of +5V decreases, the voltage detect IC (IC507) outputs "Low" level and the IC501 outputs the reset signal. Pin 28 of the SRAM becomes roughly the same voltage as the battery voltage. At this point, pin 20 (CS) of IC504 becomes high level, causing the SRAM to go into the backup mode, in which the power consumption is lower. 3. RTC Inside (IC501) Backup Circuit Operation When the power switch is turned ON, power is supplied through DA501 to the RTC (inside IC501). At this time, the voltage at pin 7 of the IC501 is +3.3V. When the power switch is turned OFF, the BAT501 supplies power to RTC through DA501. Thevoltage at pin 7 of IC501 is about +2.5V. When the power switch is OFF and the voltage of +3.3V decreases, pin 7 of RTC (IC501) becomes roughly the same voltage as the battery voltage. RTC goes into the backup mode, in which the power consumption is lower.

SUPERVISION CIRCUIT FOR THE THERMAL HEAD TEMPERATURE

1. Function The thermistor changes the resistor according to the temperature and uses the thermistor´s characteristics. The output of pin 137 of IC501 becomes a low level. Then when it becomes a high level, it triggers point A In point C, according to the voltage output time, the thermal head´s temperature is detected. After the thermal head temperature is converted to voltage in B, it is then changed to digital data in the A/D converter inside IC501. The U decides the strobe width of the thermal head according to this value. Therefore, this circuit can keep the thermal head at an even temperature in order to stabilize the printing density and prevent the head from being overheated.

Copy (Fine, Super-Fine, Half Tone) 1. Line information is read by CIS (to be used as the reference white level) via route1, and is input to IC501. Refer to 6.4.2 BLOCK DIAGRAM(P.137) 2. In IC501, the data is adjusted to a suitable level for A/D conversion in the Analog Signal Processing Section, and via route2 it is input to A/D conversion (8 bit). After finishing A/D conversion, the data is input to the Image Processing Section via route3. Then via route4 and route5, it is stored in RAM as shading data. 3. The draft’s information that is read by CIS is input to IC501 via route1. After it is adjusted to a suitable level for A/D conversion via route2, the draft’s information is converted to A/D (8 bit), and it is input to the Image Processing Section. The other side, the shading data which flows from RAM via route6 and route7, is input to the Image Processing Section. After finishing the draft’s information image processing, white is regarded as "0" and black is regarded as "1". Then via routes4 and 5, they are stored in RAM. 4. The white/black data stored as above via routes6 and8 is input to the P/S converter. The white/black data converted to serial data in the P/S converter is input to the Thermal Head via route9 and is printed out on recording paper. Note: Standard : Reads 3.58 times/mm Fine : Reads 7.7 times/mm Super-Fine : Reads 15.4 times/mm Transmission 1. Same processing as Copy items 1 - 3. 2. The data stored in the RAM of IC501 is output from IC501 via routes6 and 10, and is stored in the system bus. Via route11, it is stored in the communication buffer inside DRAM (IC503). 3. While retreiving data stored in the communication buffer synchronous with the modem, the U (inside IC501) inputs the data to the modem along route12, where it is converted to serial analog data and forwarded over the telephone lines via the NCU Section. Reception 1. The serial analog image data is received over the telephone lines and input to the modem via the NCU section, where it is demodulated to parallel digital data. Then the U (IC501) stores the data in the communication buffer DRAM (IC503) along route12. 2. The data stored in DRAM (IC503) is decoded by the U (IC501) via route12, and is stored in DRAM (IC503) via routes13 and 5. 3. Same processing as Copy item 4.

THERMAL HEAD

1. Function This unit utilizes the state of the art thermal printer technology. The ink film is chemically processed. The ink film is comprised of two parts: an ink layer and a base film. When the thermalhead s this ink film, it emits heat momentarily, and the ink layer is melted and transferred to the paper. If this continues, letters and/or diagrams appear, and the original document is reproduced.

2. Circuit Operation Refer to the block diagram and the timing chart on the following page. There are 27 driver ICs aligned horizontally on the thermal head and each one of these ICs can drive 64 heat-emitting s. This means that one line is at a density of 64×27=1728 dots=(8 dots/mm). White/Black (white=0, black=1) data in one line increment is synchronized at IC501 pin 150 (THCLK), and sent from IC501 pin 149 (THDAT) to the shift of the ICs. The shift s of the 27 ICs are connected in series, and upon the shift of the 1728 dot increment, the shift becomes filled with data, and a latch pulse is emitted to each IC from IC501 pin 151 (THLAT). With this latch pulse, all the contents of the shift s are latched to the latch s. Thereafter, through the addition of strobes from the IC501 pins (142, 143, 146), only the dot location of black (=1) among latched data activates the driver, and the current es to heat the emitting body to cause heat emission. Here, the three line strobes, STB1 to STB3, impress at intervals of 9.216 msec, as required for one-line printout. The sequence is shown on the next page. [Moreover, for the strobe width, the thermistor value inside the thermal head is detected according to IC501 pin 2. Depending on that value, the strobe width is recorded in ROM (IC502). Accordingly, the strobe width is determined.] When the thermal head is not used, the IC501 (141, THON) becomes low , Q501 turns OFF, IC508 turns OFF, and the +24V power supply for the thermal head driver is not impressed to protect the IC. 138

SCANNING BLOCK

The scanning block of this device consists of a control circuit and a image sensor made up of a celfoc lens array, an LED array, and photoelectric conversion elements.

When an original document is inserted and the start button pressed, pin 37 of IC501 goes to a high level and the transistor Q37 turns on.This applies voltage to the LED array to light it. The image sensor is driven by each of the FTG-F1 signals output from IC501, and the original image illuminated by the LED array undergoes photoelectric conversion to output an analog image signal (SIG). The analog image signal is input to the system ASIC on AIN1 (pin 1 of IC501) and converted into 8-bit data by the A/D converter inside IC501. Then this signal undergoes digital processing in order to obtain a high-quality image.

STEPPING MOTOR DRIVE CIRCUIT

1. Function The stepping motor works for both transmission and reception. 2. Motor During motor driving, pin 131 of ASIC IC501 becomes a high level, and Q503, Q502 turns ON. As a result, +24V is supplied to the motor coil. Stepping pulses are output from ASIC IC501 pins, 125, 128~130, causing driver IC508 pins, 15~12 to drive the Motor Coil. The motor coil is energized sequentially in 2 phase increments, which causes a 1-step rotation. A 1-step rotation feeds 0.13 mm of recording paper or document paper. The timing chart is below.

When the motor suspends while it is in the receive mode (about 70~80 msec), pin 131 of ASIC IC501 becomes a low level and Q503 turns OFF. Then Q502 also turns OFF, and instead of +24 V, +5 V is supplied through D501 so that the motor is held in place. When the system is in the stand-by mode, all of the motor drive transistors turn OFF. Consequently, the motor current stops.

GEAR SECTION

This model provides a motor-driven gear mechanism for transmitting/copying documents and printing fax data. In this chapter, you will see how the gears work to select and operate a mode and how the gear section, sensors and rollers mechanically work during the main operations (FAX transmission, FAX reception and Copy).

6.4.6.1.

MODE SELECTION (See Fig. 1)

When a motor with Drive Motor Gear attached rotates counterclockwise (CCW), Swing Gear C engages CAM Gear to rotate counterclockwise (CCW). This operation provide four mode options (A: Transmit mode, B: Paper-Pickup mode, C: Receive mode and D: Copy mode) selected by the Sensor Switch. (The Sensor Switch Lever’s position in the CAM Gear controlled by the software selects a specific mode.) You can see which mode is selected by confirming the Mode Marker’s position as shown in Fig. 1-a~1-d. (Ex. If the Mode Marker is in position A, a transmit mode is selected.) Note: The arrows show the directions in which the active gears turn around.

FUNCTION

The unit uses a 1 chip modem (IC505) 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. This 1 chip modem (IC505) has hardware which sends and detects all of the necessary signals for FAX communication. It can be controlled by writing commands from the U (IC501: inside ASIC) to the in the modem (IC505). This modem (IC505) 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 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. 5.

MODEM CIRCUIT OPERATION

The modem (IC505) has all the hardware satisfying the CCITT standards mentioned previously. When the ASIC IC501 (61) is brought to a low level, the modem (IC505) is chip-selected and the resistors inside IC are selected by the select signals from ASIC (IC501) ADR0-ADR4(pin 83~87). Commands are written through the data bus, and all processing is controlled by the ASIC (IC501) according to CCITT procedures. Here, the INT signal dispatched from IRQ (pin 60 of IC505) to the ASIC (IC501) implements post processing. This modem (IC505) 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 (IC505) clock is supplied by pin 55 of ASIC (IC501). 1. Facsimile Transmission/DTMF Line Send The digital image data on the data bus is modulated in the modem (IC505), and sent from pin 44 via amplifier IC501(2→1), Analog SW IC509(1→2), amplifier IC511(2→1) and the NCU section to the telephone line. Refer to 2.3.7.1 CHECK SHEET(P.74). 2. Facsimile Reception The analog image data which is received from the telephone line es through the NCU section and enters pin 45 of the modem (IC505). The signals that enter pin 45 of the modem (IC505) 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 2.3.7.1 CHECK SHEET(P.74). 3. DTMF Transmission (Monitor tone) The DTMF signal generated in the modem (IC505) is output from pin 44, and the NCU section to the telephone line the same as facsimile transmission signals. (DTMF Monitor Tone) Refer to 2.3.7.1 CHECK SHEET(P.74). 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 (IC505) becomes 1, and this status is monitored by ASIC (IC501).

LINE AMPLIFIER AND SIDE TONE CIRCUIT

1. Circuit Operation The reception signal output from the line transformer T101 is input to pin (2) of IC101 via C136, R111, C111 and R158 and then the signal is amplified at pin (1) of IC101 and sent to the reception system at 11.6dB. The transmission signal goes through C571 and R579 and enters IC511-pin (2), where the signal is amplified to about 7.4dB. Then, it is output from pin (1) of IC101 and transmitted to T101 via C117 and R110. If the side tone circuit is not applied, the transmission signal will return to the reception amplifier via C136, R111, C111 and R158. When the side tone circuit is active, the signal output from IC101 pin (1) es through C117, R113, C113, C112 and R112 and goes into the amplifier IC101 pin (3). This circuit is used to cancel the transmission return signal.

6.10. TAM INTERFACE SECTION 6.10.1. FUNCTION If EXT. TAM is selected in the Receive mode, the unit receives documents for FAX calls or the external TAM records a voice message automatically. To switch between the answering machine and facsimile in the EXT. TAM Mode. # 1

EXTERNAL TAM OPERATION When the bell signal rings as many times as the number memorized into the connected answering machine (TAM), the answering machine is connected to the line and the answering message is sent out to the line. (OGM out for 8 ~ 16 sec.)

2

After sending the OGM, the answering machine starts to record the message of the other party (ICM recording).

UNIT OPERATION The length of the answering message should be 8~16 seconds. While the message is being played, the unit starts to detect the CNG signal.(A) If the unit detects the CNG signal, it will switch to FAX receiving and disconnect the external TAM automatically. After the OGM of the external TAM is finished, the unit starts to detect approximately 5 seconds of no sound detection. (B) If no sound is detected, the unit will switch to FAX receiving and disconnect the external TAM automatically. If the unit cannot detect the CNG signal or no sound for about 30 seconds, the unit will disconnect the line. (C)

Attention 1: No sound detection lasts 20 seconds after the telephone call is received at the answering machine. If there is no sound for more than 5 seconds (#701 in the service mode), it switches to the facsimile. Attention 2: When the answering machine cannot answer the telephone call because of disconnection or the recording tape is full, the unit picks up the call after 5 rings (#702 in the service mode). Then it switches to the facsimile.

KX-FP80

6.10.2. CIRCUIT OPERATION The TAM INTERFACE circuit consists of an EXT. TAM HOOK detection circuit, CNG signal from the other party’s detection circuit, VOX detection circuit (to judge sound/no-sound) and RL101 (to separate EXT. TAM). 1. EXT. TAM HOOK detection circuit A bell is received at EXT. TAM and EXT. TAM is connected to the line, making a DC LOOP. Then, PC101 detects this voltage. During detection, PC101 (4) becomes low. (DC LOOP) Tip → L101 → JJ103 → L105 → Tip1 → (EXT.TAM) → Ring 1 → L104→ RL101(5, 3) → PC101(1, 2) → L102 → POS101 → Ring 2. CNG/VOX signal detection circuit The CNG signal from the other party’s FAX is detected in MODEM IC505 (digital board). (Signal path) Refer to 2.3.7.1 CHECK SHEET(P.74). 3. Remote receiving This is the parallel-connected DTMF signal for the TEL or EXT.TEL mode between T and R. When the other party is a FAX, the unit switches to FAX receiving. (Signal Path) Detects the DTMF signal in the MODEM.

6.12. LCD SECTION The Gate Array (IC301) works only for writing the ASCII code from the data bus (D4~D7). V0 is supplied for the crystal drive. R303(R377) and R305(R379) are density control resistors. Consequently, in this unit, the timing (positive clock) is generated by the LCD interface circuitry in the gate array (IC301).

6.13. POWER SUPPLY BOARD SECTION This power supply board uses the switching regulator method.

[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,D102,D103 and 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.

171

KX-FP80

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 E 1. 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.

172

KX-FP80

[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.

Dummy load method (to quickly check the power supply output) Refer to 2.3.8 POWER SUPPLY BOARD SECTION(P.77).
