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. 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). · Exercise care while using higher temperature soldering irons.: Do not heat the PCB for too long time in order to prevent solder splash or damage to the PCB. · 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 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.

2.2.
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.
2.3.
Battery Caution
Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type recommended by the manufacturer. Dispose of used batteries according to the manufacturer's instruction. CAUTION: The lithium battery is a critical component (type No. CR2032). Please observe for the proper polarity and the exact location when replacing it and soldering the replacement lithium battery in.

RTC Backup Circuit
1. Function This unit has a lithium battery (BAT501) which works for Real Time Clock IC (RTC: inside IC501). The RTC continues to work, backed up by a lithium battery even when the power switch is OFF. The user parameters for autodial numbers, the system setup data and others are in the FLASH MEMORY (IC506). 2. RTC Inside (IC501) Backup Circuit Operation When the power switch is turned ON, power is supplied through Q505 to the RTC (inside IC501). At this time, the voltage at pin 14 of the IC501 is +2.5V. When the power switch is turned OFF, the BAT501 supplies power to RTC through D501 and Q505. The voltage at pin 14 of IC501 is about +2.2V. When the power switch is OFF and the voltage of +3.3V decreases, pin 14 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 Terminal Head Temperature
1. Function The thermistor changes the resistor according to the temperature and uses the thermistor's characteristics. The output of pin 139 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 CPU 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 Block Diagram (P.23) 2. In IC501, the data is adjusted to a suitable level for A/D conversion in the Analogue 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 3.85 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 retrieving data stored in the communication buffer synchronous with the modem, the CPU (inside IC501) inputs the data to the modem along route12, where it is converted to serial analogue data and forwarded over the telephone lines via the NCU Section. Reception 1. The serial analogue 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 CPU (IC501) stores the data in the communication buffer DRAM (IC503) along route12. 2. The data stored in DRAM (IC503) is decoded by the CPU (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 contacts 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 9 driver ICs aligned horizontally on the thermal head and each one of these ICs can drive 192 heat emitting registers. This means that one line is at a density of 192×9=1728 dots=(8 dots/mm). White/Black (white=0, black=1) data in one line increments is synchronized at IC501 pin 117 (THCLK), and sent from IC501 pin 116 (THDAT) to the shift register of the ICs. The shift registers of the 9 ICs are connected in series, and upon the shift of dot increment 1728, all the shift registers become filled with data, and a latch pulse is emitted to each IC from IC501 pin 118 (THLAT).With this latch pulse, all the contents of the shift registers are latched to the latch registers. Thereafter, through the addition of strobes from the IC501 pins (103, 104) only black dot locations (=1) among latched data activates the driver, and the current passes to heat the emitting body causing heat emission. Here, the two line strobes, STB1 and STB2, 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 4. Depending on that value, the strobe width is recorded in ROM (IC506). Accordingly, the strobe width is determined. When the thermal head is not used, the IC501 (17, THON) becomes low, Q502 turns OFF, Q401 turns OFF, and the +24 V power supply for the thermal head driver is not impressed to protect the IC.

Scanning Block
The scanning block of this device consists of a control circuit and a contact image sensor made up of a celfoc lens array, an LED array, and photoelectric conversion elements.
When an original document is inserted and the start button pressed, pin 34 of IC501 goes to a high level and the transistor Q506 turns on.This applies voltage to the LED array to light it. The contact 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 analogue image signal (AIN). The analogue image signal is input to the system ASIC on AIN1 (pin 3 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 124 of ASIC IC501 becomes a high level, and Q403, Q402 turns ON. As a result, +24V is supplied to the motor coil. Stepping pulses are output from ASIC IC501 pins, 124, 120~123, causing driver IC401 pins, 14~11 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 124 of ASIC IC501 becomes a low level and Q403 turns OFF. Then Q402 also turns OFF, and instead of +24 V, +6 V is supplied through D401 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.

Modem Section
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 analogue 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 CPU (IC501: inside ASIC) to the register 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.

Signal Training 1 Identification Signal Format -------------- Function A fixed pattern is transmitted to the receiving side at a speed (2400 to 14400 bps) designated by DCS, and the receiving side optimizes the automatic equalizer, etc., according to this signal. Sends 0 continuously for 1.5 seconds at the same speed as the training signal. Notifies the sending side that TCF has been properly received. If TCF is not properly received, FTT (Failure To Train) X0100010 is relayed to the sender. The sender then reduces the transmission speed by one stage and initiates training once again. Used for reconfirming the receiving side like training 1. -------------- Sends 12 bits (0...01 × 6 times) to the receiver at the same speed as the image signal and notifies completion of transmission of the first sheet. End of one communication End of 1 page reception Phase E starts. Completion of transmission of 1 page. If there are still more documents to be sent, they are output instead of EOP. After MCF reception, the sender transmits an image signal of the second sheet. If there is an operator call from the sender, it is output after RTC. This is output when an operator call is received.

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. The commands are written through the data bus, and all the processing is controlled by the ASIC (IC501) according to CCITT procedures. The INT signal dispatched from IRQn (pin 100 of IC505) to ASIC (IC501) when the transmission data is accepted and the received data is demodulated, the ASIC (IC501) implements post processing. This modem (IC505) has an automatic application equalizer. With training signal 1 or 2 during G3 reception, it can automatically establish the optimum equalizer. The modem (IC505) operates using the 32.256 MHz clock (X503). 1.Facsimile Transmission The digital image data on the data bus is modulated in the modem (IC505), and sent from pin 56 via Analogue SW IC508, amplifier IC511 and the NCU section to the telephone line. Refer to Check Sheet for Signal Route (P.123). 2.Facsimile Reception The analogue image data which is received from the telephone line passes through the NCU section and enters pin 47 of the modem (IC505). The signals that enter pin 47 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 about 3 kHz and maintain a constant receiving sensitivity. It can be set in the service mode. Refer to Check Sheet for Signal Route (P.123). 3.DTMF Transmission (Monitor tone) The DTMF signal generated in the modem (IC505) is output from pin 56, and is then sent to the circuit on the same route as used for facsimile transmission. Refer to Check Sheet for Signal Route (P.123). (DTMF Monitor Tone) Refer to Check Sheet for Signal Route (P.123). 4.Call Tone Transmission This is the call signal which is generated in the ASIC (IC501) and sent to the speaker. Refer to Check Sheet for Signal Route (P.123). 5.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 the ASIC (IC501). 6.Caller ID Detection The caller ID signal which is received from the telephone line/passes through IC101 pin (2-1). And it enters pin 50 of the modem (IC505).

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 C110 and R109 and then the signal is amplified at pin (2) of IC101 and sent to the reception system at 0dB. The transmission signal is output from CN101 (6) and transmitted to T101 via R120 and R119. If the side tone circuit is not applied, the transmission signal will return to the reception amplifier via C110 and R109. When the side tone circuit is active, the signal output from IC101 pin (1) passes through R114, R113, C113 and R112 and goes into the amplifier IC101 pin (3). This circuit is used to cancel the transmission return signal.

Calling Line Identification Circuit
1. Function This unit is compatible with the Caller ID service offered by your local telephone company. To use this feature, you must subscribe to a Caller ID service. The data for the Caller ID from the telephone exchange is sent during the interval between the first and second rings of the bell signal. The data from the telephone exchange is a modem signal which is modulated in an FSK (Frequency Shift Keying) format. Data "0" is a 1200 Hz sine wave, and data 1 a 2200 Hz sine wave. There are two type of the message format which can be received:i.e.the single data message format and multiple data message format. The multiple data format allows to transmit the name and data code information in addition to the time and telephone number data. When there is multiple data in the unit, the name or telephone number are displayed. 2. Circuit Operation: The Caller ID signal input from TEL LINE is processed with MODEM (IC505). Refer to Check Sheet for Signal Route (P.123) for the route of Caller ID signal.

[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.

The following is an overview of how the power supply unit is controlled. The control method of this power supply unit is pulse width modulation. When Q1 is ON, the energy is charged in the transfer primary coil according to E1. When Q1 is OFF, the energy is output from the secondary transfer as follows. L D1 Load L Then the power is supplied to the Load. When Q1 is ON, power is not output from the secondary side. The output voltage is fed back in the control IC according to the error amp rectifier. Then depending on how TON is controlled, stabilization occurs. Also, when the current load becomes too large, in order to decrease the voltage output, the increase in voltage is stabilized. Therefore, basically the timing: Ton/Toff of Q1 controls the output voltage. is controlled and the output

[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 Power Supply Board Section (P.128).
