Use of Document Carrier Sheet TELEPHONE JACK A document carrier sheet must be used for the following documents. • Those with tears. A standard telephone jack must be located near the machine. This is the telephone jack commonly used in most homes and offices. • • • Those smaller than size 140 mm (W) x 140 mm (L). Carbon-backed documents Make print straight across paper E.G. Place the document carrier in the document feeder with the clear film side down Plugging the fax machine into a jack which is not an jack may result in damage to the machine or your telephone system. If you do not know what kind of jack you have, or needed to have one installed, contact the telephone company. 2. Connections 1 Connect the handset as shown and place it on the handset rest. ♦ Make sure the handset cord goes into the unmarked jack on the side of the machine! ♦ Use the handset to make ordinary phone calls, or to transmit and receive documents manually. Direction of insertion NOTE: To transmit a carbon-backed document, insert a white sheet of paper between the carbon back of the document and the document carrier. • Those containing an easily separable writing substance (e.g., tracing paper written on with a soft, heavy lead pencil). NOTES: • When using the document carrier, carefully read the instructions written on the back. • If the document carrier is dirty, clean it with a soft, moist cloth, and then dry it before using for transmission. • 2 Plug the power cord into a 220-240 V, 50 Hz, earthed (2-prong) AC outlet. ♦ Caution: Do not plug the power cord into any other kind of outlet. This will damage the machine and is not covered under the warranty. Do not place more than one document in the carrier at a time. Note: The shape of the plug is different in certain countries. [4] Installation ♦ The machine does not have a power on/off switch, so the power is turned on and off by simply plugging or unplugging the power cord. 1. Site selection Take the following points into consideration when selecting a site for this model. Note: If your area experiences a high incidence of lightning or power surges, we recommend that you install surge protectors for the power and telephone lines. Surge protectors can be purchased from your dealer or at most telephone specialty stores. ENVIRONMENT • • The machine must be installed on a level surface. • Provide easy access to the front, back, and sides of the machine. In particular, keep the area in front of the machine clear, or the original document may jam as it comes out after scanning. • • The temperature should be between 5° and 35°C. Keep the machine away from air conditioners, heaters, direct sunlight, and dust. 3 Insert one end of the telephone line cord into the "TEL. LINE" jack. The humidity should be between 30% and 85% (without condensation). Insert the other end into a standard (RJ11C) single-line telephone wall jack. ELECTRICITY ♦ Be sure to insert the telephone line cord into the "TEL. LINE" jack. Do not insert into the "TEL. SET" jack. 220-240 V, 50 Hz, earthed (2-prong) AC outlet is required. Caution! • Connection to a power source other than that specified will cause damage to the equipment and is not covered under the warranty. • If your area experiences a high incidence of lightning or power surges, we recommend that you install a surge protector for the power and telephone lines. Surge protectors can be purchased at most telephone specialty stores. If the machine is moved from a cold to a warm place... If the machine is moved from a cold to a warm place, it is possible that the reading glass may fog up, preventing proper scanning of documents for transmission. To remove the fog, turn on the power and wait approximately 2 hours before using the machine. TE SEL. T T EL LI .

Automatic document feed CHAPTER 3. MECHANISM BLOCKS 1) Use of the paper feed roller and separation rubber plate ensures error-free transport and separation of documents. The plate spring presses the document to the paper feed roller to assure smooth feeding of the document. [1] General description 2) Document separation method: Separation rubber plate 1. Document feed block and diagram Separator rubber Paper feed spring Separator rubber Paper feed spring Rear roller A/B Transfer roller Document Document Paper feed roller Paper feed roller CIS Pinch roller Fig. 3 3-3. Documents applicable for automatic feed Fig. 1 Square meter series 4x6 series (788mm x 1091mm x 1000mm sheets) 2. Document feed operation Minimum 1) The document placed in the hopper actuates the document sensor. After one second, the pulse motor starts to drive the paper feed roller. The document is automatically taken up into the machine, and stopped at the document sensor. Feeder capacity Paper weight Maximum Minimum Maximum 52g/m2 74.3g/m2 10 sheets, max. 45kg 64.3kg Paper thickness (ref.) 0.06mm 0.09mm 0.06mm 0.09mm Paper size 1/2 Letter (148mm x 140mm) ~ A4 (210mm x 297mm), Letter (216mm x 279mm) 2) When a specified number of pulses are received from the document sensor after the document lead edge is sensed, scanning is started. 3) When a specified number of pulses are received from the document sensor after the document rear edge is sensed, scanning is terminated and the document is fed through. NOTE: Double-side coated documents and documents on facsimile recording paper should be inserted manually. The document feed quantity may be changed according to the document thickness. 4) If the document sensor is active (i.e., another document is in the hopper), when the preceding document scanning is completed and it is fed out, the next document is taken up into the machine. If the document sensor is not active (i.e., there is no document in the hopper), when the document is fed out, the operation is terminated. Documents corresponding to a paper weight heavier than 64.3kg (74.3g/ m2 ) and lighter than 135kg (157g/m2 ) are acceptable for manual feed. Documents heavier than 135kg in terms of the paper weight must be duplicated on a copier to make it operative in the facsimile. 3. Hopper mechanism 3-4. Loading the documents 3-1. General view 1) Make sure that the documents are of suitable size and thickness, and free from creases, folds, curls, wet glue, wet ink, clips, staples and pins. 2) Place documents face down in the hopper. i) Adjust the document guides to the document size. ii) Align the top edge of documents and gently place them into the hopper. The first page under the stack will be taken up by the feed roller to get ready for transmission. NOTES: 1) Curled edge of documents, if any, must be straighten out. 2) Do not load the documents of different sizes and/or thicknesses together. Separator rubber Paper feed spring Fig. 2 Last page of document Back of document The hopper is used to align documents with the document guides adjusted to the paper width.

Cross section view Platen roller Cutter cover Cutter guide Cutter unit Fig. 6 5-2. Driving Operation panel unit Via the pulse motor gear shaft, the reduction gear, and the recording paper feed gear, rotation of the pulse motor is conveyed to the recording paper feed roller to feed the recording paper. 5-3. Recording Scanner frame unit Use of a thermal head permits easier maintenance and low operating costs. PWB case unit 1) Thermal head The thermal head consists of 1728-dot heat elements arranged in a single row and has the resolution of 8 dots/mm. The maximum recording speed is 10ms/line. The thermal head also incorporates a 1728-dot shift register latch and output control driver circuit. Low power consumption is achieved by dividing the head into nine segments. 2) Structure of the recording mechanism Recording is accomplished by pressing the thermal head on the recording paper against the platen roller. Lower cabinet The main scan (horizontal) is electronically achieved, while the subscan (vertical) is achieved by moving the recording paper by the recording platen roller. Fig. 5 Usually, the cause for uneven print tone is caused by misalignment of the thermal head or uneven contact with the roller. It can be checked in the following manner. 1) Check if the thermal head power and signal cables are properly routed. 2) Check that the thermal head pivot moves smoothly up and down. 3) Check that the thermal head support bracket is secured without any play. 4) Check to see that the recording platen roller has proper concentricity, in the case of a print tone variation evenly repeated down the page. 5) Replace the thermal head with a new one and check to see if the same trouble occurs. 3–2 UX-258TH FO-475TH [2] Disassembly and assembly procedures • • This chapter mainly describes the disassembly procedures.

Operational description CHAPTER 5. CIRCUIT DESCRIPTION Operational descriptions are given below: • [1] Circuit description When a document is loaded in standby mode, the state of the document sensor is sensed via the 1 chip fax engine (FC200). If the sensor signal was on, the motor is started to bring the document into the standby position. With depression of the START key in the off-hook state, transmission takes place. Then, the procedure is sent out from the modem and the motor is rotated to move the document down to the scan line. In the scan processor, the signal scanned by the CIS is sent to the internal image processor and the AD converter to convert the analog signal into binary data. This binary data is transferred from the scan processor to the image buffer within the RAM and encoded and stored in the transmit buffer of the RAM. The data is then con-verted from parallel to serial form by the modem where the serial data is modulated and sent onto the line. 1. General description The compact design of the control PWB is obtained by using ROCKWELL fax engine in the main control section and high density printing of surface mounting parts. Each PWB is independent according to its function as shown in Fig. 1. 2. PWB configuration TEL/LIU PWB • LCD PWB CONTROL PWB Receive operation There are two ways of starting reception, manual and automatic. Depression of the START key in the off-hook mode in the case of manual receive mode, or CI signal detection by the LIU in the automatic receive mode. POWER SUPPLY PWB PANEL PWB Transmission operation First, the FC200 controls the procedure signals from the modem to be ready to receive data. When the program goes into phase C, the serial data from the modem is converted to parallel form in the modem interface of the 1 chip fax engine (FC200) which is stored in the receive buffer of the RAM. The data in the receive buffer is decoded software-wise to reproduce it as binary image data in the image buffer. The data is DMA transferred to the recording processor within the FC200 which is then converted from parallel to serial form to be sent to the thermal head. The data is printed line by line by the FC200 which is assigned to control the motor rotation and strobe signal. AC CORD TX/RX MOTOR Fig. 1 1) Control PWB • The control PWB controls peripheral PWBs, mechanical parts, transmission, and performs overall control of the unit. This machine employs a 1-chip modem (R96V24) which is installed on the control PWB. Copy operation To make a copy on this facsimile, the COPY key is pressed when the machine is in stand-by with a document on the document table and the telephone set is in the on-hook state. First, depression of the COPY key advances the document to the scan line. Similar to the transmitting operation, the image signal from the CIS is converted to a binary signal in the DMA mode via the 1 chip fax engine (FC200) which is then sent to the image buffer of the RAM. Next, the data is transferred to the recording processor in the DMA mode to send the image data to the thermal head which is printed line by line. The copying takes place as the operation is repeated. 2) TEL/LIU PWB This PWB controls connection of the telephone line to the unit. 3) Power supply PWB This PWB provides voltages of +5V and +24V to the other PWBs. 4) Panel PWB The panel PWB allows input of the operation keys. 5) LCD PWB This PWB controls the LCD display. 5–1 UX-258TH FO-475TH 2) 27C020 (IC8): pin-32 DIP (ROM) [2] Circuit description of control PWB EPROM of 2Mbit equipped with software for the main CPU. 1.

The modem models are identified in Table. These functions are supplied in a single VLSI device or two-device set (for speakerphone). The MDP (modem data pump) is packaged in a 100-pin PQFP. The MDP contains an internal integrated analog codec (IIA) and is pin-compatible with the R96V24 MONOFAX modems. This device family enables cost-effective development of a common facsimile machine design with digital answering machine and/or full-duplex speakerphone. The modem can operate at 9600, 7200, 4800, 2400, or 300 bps, and can perform HDLC framing per T.30 at all rates. A programmable DTMF detector, three programmable tone detectors, and Caller ID demodulator are provided. The DigiTalk™ V24 voice coder/decoder (codec) compresses voice at an average rate of 2.9 kbps or at a fixed rate of 4.7 kbps with near toll quality playback. An average rate of 2.9 kbps provides 24 minutes of stored voice messages in 4 Mbits of memory. This voice codec allows the host controller to efficiently store and playback digital incoming messages (ICMs) and outgoing messages (OGMs). The ADPCM audio codec compresses audio signals (e.g., music/voice) at 32 kbps or 24 kbps for highest fidelity coding and reproduction. Selectable error correction coding allows storage in audio grade RAMs (ARAMs).

Noise filter circuit The input noise filter section is composed of L and C, which reduces normal mode noise from the AC line and common mode noise to the AC line. The overvoltage protection is performed by operating the overcurrent protection circuit through destruction of zener diode ZD4 and shortcircuiting of load. 2-2. Rectifying/smoothing circuit The AC input voltage is rectified by diode D1, 2, 3, 4 and smoothed by capacitor C5 to supply DC voltage to the switching circuit section. 2-4. +5V circuit Each DC voltage supplied by rectifying the output of transformer T1 with diode D8 is stabilized by 3-terminal regulator IC1. Power thermistor TH1 suppresses inrush current at power switch-on. 2-3. Switching circuit 2-5. VTH circuit This circuit employs the self excited ringing choke convertor (RCC) system. In this system, the DC voltage supplied from the rectifying/smoothing section is converted into high frequency pulses by ON/OFF repetition of MOS FET Q1. VTH output is supplied through the relay RY1. Relay RY1 is operated by VTH-ON signal. Energy is charged in the primary winding of T1 during ON period of Q1, and discharged to the secondary winding during OFF period. The output voltage is controlled by adjusting ON period of Q1 which changes charge time of C9 through operation of photo-coupler PC1 from +24V output. [5] Circuit description of CIS unit 1. CIS 2. Waveforms Cis is an image sensor which puts the original paper in close contact with the full-size sensor for scanning, being a monochromatic type with the pixel number of 1,728 dots and the main scanning density of 8 dots/mm. It is composed of sensor, rod lens, LED light source, light-conductive plate, control circuit and so on, and the reading line and focus are previously adjusted as the unit. Due to the full-size sensor, the focus distance is so short that the set is changed from the light weight type to the compact type.
