2 Warning 2.1.

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).

2.1.1.

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.

KX-MB262CX/KX-MB772CX

2.2.

Discarding of P. C. Board

When discarding P. C. Board, delete all personal information such as telephone directory and caller list or scrap P. C. Board.

2.3.

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.

2.4.

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 account for their ultimate disposition. This is a good practice for all types of commercial or industrial waste. Recommend Type Number: CR2354 (BAT300) Manufactured by MATSUSHITA

RTC BACKUP CIRCUIT (KX-MB772CX ONLY)

1. Function This unit has a lithium battery (BAT300) which works for the Real Time Clock IC (RTC: inside IC300). The RTC continues to work, backed up by a lithium battery even when the power switch is OFF. 2. RTC Inside (IC300) Backup Circuit Operation When the power switch is turned ON, power is supplied to the RTC (inside IC300). At this time, the voltage at pin AD4 of the IC300 is +3.3V. When the power switch is turned OFF, the BAT300 supplies power to RTC through DA300. When the power switch is OFF and the voltage of +3.3V decreases, pin AD4 of RTC (IC300) becomes roughly the same voltage as the battery voltage. RTC goes into the backup mode, in which the power consumption is lower.

MODEM CIRCUIT OPERATION (KX-MB772CX ONLY)

The modem (Included IC300) has all the hardware satisfying the CCITT standards mentioned previously. ALL processing is controlled by the SOC (IC300) according to CCITT procedures. This modem (Included IC300) has an automatic application equalizer. With training signal 1 or 2 at the time of G3 reception, it can automatically establish the optimum equalizer. Facsimile Transmission/DTMF Line Send The digital image data sent on ATXD line from modem (Included IC300) . DAA IC100(6→9,10), Line side DAA IC101 and the NCU section to the telephone line. Facsimile Reception The analog image data which is received from the telephone line passes through the NCU section and enters line side DAA*1 IC100. The signals are changed to digital data in IC100 (5,6) ,IC101(9,10→5) and IC300. In this case, the image signals from the telephone line are transmitted serially. 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. Busy/Dial Tone Detection The path is the same as Facsimile Reception. Call Tone Transmission This is the call signal which is generated the SOC (IC300) and sent to the speaker.

CIS CONTROL SECTION

The scanning block of this device consists of a control circuit and a CIS (contact image sensor), and AFE (Analog Front End) include A/D Converter.

When an original document is inserted and the start button pressed, pin A3 of IC300 goes to a low level and the transistor Q518 turns on. This applies voltage to the CIS. The CIS is driven by each of the CCDSH , CCDCLK signals output from IC300, and the original image illuminated by the LED to output an analog image signal. The analog image signal is input to the AFE on VINP(20pin of IC503) and converted into 16-bit data by the A/D converter inside IC503. Then this signal undergoes digital processing in order to obtain a high-quality image.

SCANNER MOTOR DRIVE CIRCUIT

General Scanner motor drive circuit is consist of motor current control circuit ,FB (Flat Bed) motor driver and ADF (Auto Document Feeder: equipped model only) motor driver .

6.7.2.1.

MOTOR CURRENT CONTROL CIRCUIT

1. Circuit explanation According to the scan speed, each motor current is controlled for appropriate value. When scan speed is low, motor current is reduced to prevent the vibration during motor rotation. When scan speed is high, motor needs much driving force. so much current should be supplied. For the control of motor current, Vref voltage of each motor driver is controlled. When Vref voltage is high, motor current is increased, and the voltage is low, motor current is reduced. In order to control Vref voltage, PWM pulse is supplied from IC300 pin D8 . PWM pulse is inverted by Q521 and integrated by R533, R534, and C567, then convert to DC voltage. This DC voltage is supplied to Vref pin of each motor driver through Q522. When duty of PWM pulse is high, Vref voltage is decreased and when duty is low, Vref voltage is increased. For FB motor, motor current is controlled approx. 0.1A-0.25A. For ADF motor, motor current is controlled approx. 0.2A-0.35A (ADF epuipped model only). 2. Circuit diagram

FAN CONTROL

This unit is equipped with two FANs to prevent the developing devices from overheating during printing. The FAN rotates at high speed (Approx. 3000rpm) while printing (controlling the developing devices). After printing is finished, FAN rotates at low speed (Approx.2200rpm) while predetermined period. 1. Full speed control To rotate the FANs with full speed, constant high level are output from A11 and D11 of IC300. Then Q512/Q510 and Q519/ Q520 are all turned on. So 24V are output from collectors of Q510 and Q520. Since each FAN consumes approx. 0.1A, approx. 4V is reduced through R525 and R530. Then approx. 20V are supplied to each FANs. 2. Half speed control To rotate the FANs with half speed, pulse signals are output from A11 and D11 of IC300. Then all Q512/Q510 and Q519/Q520 repeat ON and OFF according to the pulse duty (30KHz/12.5%). These pulses are integrated by R525/C515 and R530/C518 and converted to DC voltage. So approx. 12V are supplied to each FANs.

6.12.9. 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 (IC50) turns off, and the input signal of IC300-AE22pin (Main Board) becomes a High level over 9s. When the Drum unit is set, Hall IC (IC50) turns ON/OFF. If the time of IC300-AE22pin's Low level is under 600ms, there is enough toner in Drum 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 Hall IC becomes short when toner is left and long with no toner. State Toner Set (full) Near Empty Toner Mixing Paddle does not rotate (“CHANGE DRUM”)

[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 circuit is rectified by D10 to D13 and charge C5 to make DC voltage. Then it supplies power to the converter circuit. [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. [Over Current Limiter (O.C.L)] The highest drain current of Q1 is limited by a limit current circuit. 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, Control circuit will recognize this signal and output becomes 0V. D104 and D503 also prevent over voltage. Dummy load method (to quickly check the power supply output) Refer to POWER SUPPLY BOARD SECTION (P.175).

12.2. REMOTE PROGRAMMING (KX-MB772CX ONLY) 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.97)). 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 (KX-MB772CX ONLY)(P.96). 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.

12.3. TROUBLESHOOTING DETAILS 12.3.1. 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 Main PCB, Sensor 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.104). Difficult problems may be hard to determine, so repeated testing is necessary.

12.3.2. STARTING TROUBLE SHOOTING Determine the symptom and the troubleshooting method.

12.3.3. 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.

12.3.6. 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.38). • 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.38) • This can be judged only by referring to signal. Check 5V line, XHSYNC, XAPC, XVIDEO, XLDON. Call Service 3 ----- Detection of fixing temperature.......... Refer to HEAT LAMP CONTROL CIRCUIT (P.52) • *Service mode *655 tells the detection number and 3 latest temperatures of the thermistor. The detection point 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 detection points and BB, DD and FF show their temperature detection 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 (195°C: 44h/200°C: 40h) within 70 seconds after reaching the first stabilizing temperature (170°C: 5Bh). 04: means that it dropped to 155°C: 6Ch/160°C: 66h (-40 deg) or below by the temperature control after reaching the second stabilizing temperature (195°C: 44h/200°C: 40h). 05: means that it did not reach the first stabilizing temperature (170°C: 5Bh) within 30 seconds from detection temperature 1 (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.

Once “CALL SERVICE3” is displayed, it does not disappear until the Factory Setup or Service Function #529 is executed.

Therefore Service Function #529 should not 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.35) • 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. Service mode *677 :1... Normal operation (default) :2... Right Fan ON (High speed) :3... Right Fan ON (Low speed) :4... Left Fan ON (High speed) :5... Left Fan ON (Low speed) :6... Both Fan OFF Call service 5 ----- Rotation of Engine motor.......... Refer to MOTOR DRIVE SECTION (P.28) • Engine motor’s rotation detection signal LD did not become Low within rated speed ±6.25%. • Service mode *556: the operation of Main Motor can be checked by pressing 0 and SET buttons. Call service 6 ----- Detection of Charger error.......... Refer to the HVPS (High Voltage Power Supply) SECTION (P.50) • Breaking of charger’s wire of Drum Unit and/or loose connection of High voltage terminals (CHRG, GRID). • First, replace the Drum unit even so, it doesn’t function check the high voltage power supply. * As for Call Service 1, 2, 4, 5 and 6, turn the power OFF then ON to restart.

Refer to the SERVICE FUNCTION TABLE (KX-MB772CX) (P.85). 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.93) for the above items. Also, when it actually becomes a hardware deformity, please check each sensor.

This comes from our experience with experimental test. For example: power supply and lightning surge voltage test, with standing 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 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 secondary side. Check the primary side first.

15.3. PRINTING OPERATION PRINCIPLE 15.3.1. PROCESS CHART AND PROCESS BIAS

15.3.2. 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 Transfer Layer (CGTL). When the charging bias (DC +4.35kv) is added and the plus charge is supplied to the OPC surface while charging, the whole surface potential of the drum is +475V.

Charging Part

218

KX-MB262CX/KX-MB772CX

15.3.3. 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 Transfer Layer. Passing through the Charge Generation Transfer Layer which conducts the minus charge, the plus-charged drum's surface is neutralized to be skipped. Then the plus 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.

15.3.5. 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 consists of mixing paddle, toner supply roller, developing roller, developing blade, charge wire, grid plate and OPC drum. The bias voltage is added to the developing roller and toner supply roller. Firstly the toner is mixed up in the mixing paddle and plus-charged 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 minuscharged 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-MB262CX/KX-MB772CX

15.3.6. 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 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. After paper jam or replacing toner and drum unit, the transfer roller is plus-charged to eliminate the plus-charged toner.

Cleaning Part

221

KX-MB262CX/KX-MB772CX

15.3.7. 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 two thermostats 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 195°C while printing. 2. Thermostat The thermostat is located near the heat roller, and it turns OFF the power when the temperature around the thermostat becomes over 160°C.

15.5. 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.

15.5.1. PREPARATION • PbF (: Pb free) Solder • Soldering Iron Tip Temperature of 700°F ± 20°F (370°C ± 10°C) Note: We recommend a 30 to 40 Watt soldering iron. An expert may be able to use a 60 to 80 Watt iron where someone with less experience could overheat and damage the PCB foil. • Flux Recommended Flux: Specific Gravity → 0.82. Type → RMA (lower residue, non-cleaning type) Note: See ABOUT LEAD FREE SOLDER (PbF: Pb free) (P.5.)

15.5.2. 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 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.

225

KX-MB262CX/KX-MB772CX

15.5.3. FLAT PACKAGE IC INSTALLATION PROCEDURE 1. Temporarily fix the FLAT PACKAGE IC, soldering the two marked pins.

*Check the accuracy of the IC setting with the corresponding soldering foil. 2. Apply flux to all pins of the FLAT PACKAGE IC.

3. Solder the pins, sliding the soldering iron in the direction of the arrow.

15.5.4. BRIDGE MODIFICATION PROCEDURE 1. Lightly resolder the bridged portion. 2. Remove the remaining solder along the pins using a soldering iron as shown in the figure below.

15.6. MAIN 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 GENERAL BLOCK DIAGRAM (P.11). The ASIC (IC300) controls all the other digital ICs. When the power is turned on, the ASIC retrieves the operation code stored in the ROM (IC402), 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).
