2.2 Main Control PCB The main control PCB controls the operations of all machine functions. Jumper JP2 on the main control PCB is used for battery back-up of the SDRAM. Removing JP2 will initialize the SDRAM. If the power is turned off, the battery will provide up to 72 hours (8MB) of back-up when fully charged. Jumper JP1 on the main control PCB is used for battery back-up of the SRAM. All user programmed data and internal memory switch settings are held in SRAM. Removing JP1 will initialize the SRAM.

2.3 Network Control Unit (NCU) PCB The NCU PCB provides the connection to the telephone line. It consists of the interface circuit, dial pulse generator, ring signal detector and telephone control circuit. MODULAR PCB NCU PCB TXA RXA S DP GENERATOR TONE OH CI +24V, +5V, GND +12V, -12V NCU PCB block diagram Major components of the NCU CML relay Connects the telephone line to the phone or fax. S relay Used to send dial pulse signals in pulse dialing.
2.4 Power Supply Unit (PSU) The power supply unit receives the input line voltage and currents it to output voltages of +5 VDC, +24 VDC, +12 VDC, and -12 VDC. The heater circuit controls output voltage to the fuser heater according to instructions received from the heater control circuit. If an over-current is sensed in the secondary circuit, power is interrupted. Power supply unit block diagram The power supply unit has two output connectors.
2.5 Sensors 2.5.1 Sensor Locations The following illustration shows the relative positions of the machine’s sensors.
2.5.2 Sensor Descriptions The following table gives a brief description of each sensor and its function.
2.6 Document Scanning Sequence 2.6.1 Document Detection When a document is placed into the document feeder, Document Sensor 1 (DS1) is activated and you will hear the short beep. 2.6.2 Document Separation Document separation is the process that allows a multi-page document to go through the scanner one page at a time. Separation occurs through the action of the separator roller and retard roller. As shows in the illustrations, documents in the feeder are pressed against the separator roller.
When DS2 detects the trailing edge of the document, the image signal output is turned off. The scanner continues to remain active for a few more seconds in case there is another document to follow. Press roller A Separator roller Pick up roller Retard roller Feed roller A DS1 Feed roller B Press roller A DS2 Exit roller CCD Press roller B Lens Mirror B Mirror A Mirror C Document scanning in ADF section Scanner unit End sensor Home sensor Document scanning in FBS section 2.6.
2.7 Recording Section 2.7.1 Recording Paper Feed Path A sheet of the recording paper is separated from the remaining paper by the friction of the pickup roller. The paper is moved along the paper guide until it reaches the platen roller. Is then fed by the rotation of the platen roller. 2.8 Image Processing Incoming data is received from the telephone line by the NCU and sent to the main control PCB. The modem, located on the main control PCB, demodulates the data.
2.8.1 Drum Charge • The Drum is charged with static electricity before LED exposure. The Rotating Charge Brush is used for the charging method. • The rotating brush charging generate little ozone in the printer. Because the charge is directly given to the Drum, the Drum can be charged by low voltage. At the same time, the Drum can be charged stably and evenly. 2.8.2 Drum Exposure An invisible static image is made by the light from the LED print head.
2.8.4 Image Transfer Image transfer is the process of transferring the toner image created on the Drum in the developing process to paper. We use the Roller Image Transfer instead of the Corona Image Transfer, as the image transfer method. In the Roller Image Transfer, there is little generation of ozone due to corona discharge. Also, there is no blur of toner because the paper is always pressed by the Drum and the Image Transfer Roller. PC Drum Image transfer roller Hight voltage unit + output 2.8.
2.8.6 Fusing An Overview The toner image transferred on to the paper is securely fixed. A heat roller system is used as the fusing system. The toner image is fused by Heater Roller heated by the Heater Lamp, and securely fixed by the pressure between the Heater roller and Press rollers. A Thermistor detects and controls the Heater Roller temperature. The Thermostat functions when the Heater Lamp is not turned OFF even if the Thermistor detects a high temperature malfunction.
Fusing temperature 1) Warming Up After the initialization of the printer, warming up of the printer starts and the Heater Lamp turns ON until the temperature of the Heater Roller reaches approx. 180 °C. 2) Printing When the printer obtains the printing command from its controller, the Heater Roller is maintained at 180 °C. After printing, the printer turns to standby mode. The fuser kept at low temperature. 3) Standby mode The Heater Roller maintained at approx. 160 °C.

Section4 Troubleshooting Procedures 4.1 Troubleshooting Outline Before troubleshooting a unit check the following: • • • • Is the power cord correctly connected to the machine? Is the telephone handset and the telephone line cord connected correctly? Is there paper in the paper cassette? Are all covers closed correctly? Before removing any portions of the machine or making any adjustments be sure the power cord is disconnected from the unit.
4.2 Recording Paper Jam Symptom: Recording paper did not exit paper cassette properly or jam occurred in print area. Suggested corrective action: 1. Verify that the recording paper conforms to the type specified for use in the machine and that has not been damaged or exposed to moisture. 2. Make sure the recording paper is properly loaded into the multipurpose tray and cassette and the cassette is properly closed. 3. Clean the paper feed rollers of any paper dust buildup.
4.4 Document Feeder Multi-feeding or Skew Symptom: Two or more pages of a multi-page document are fed at once. The document is fed on the skew. Slight skewing may sometimes occur. Suggested corrective action: 1. Verify that the original documents conform to the specifications designed for use in the machine and they are not damaged in any way. 2. Verify the pages of the document are not stuck together from glue, wet or damp correction fluid, tape, etc. 3.
4.8 Cannot transmit Symptom: The unit will not transmit Suggested corrective action: 1. Verify the telephone line cord is properly installed and plugged into the correct type of wall jack. 2. Check for dial tone at the unit and wall jack. If no dial tone is present at the unit, check the NCU PCB. 3. Verify that the correct telephone number has been dialed or that the correct telephone number is programmed in the autodialer. 4. Insure Security TX turned off. 5.

Check the connection between RX motor and the Connect Printer PCB (P1308). (See page 2-1.) 3. Replace the RX motor if it doesn’t rotate. 4. If the problem is not correct, replace the main control board. Drum Fuse Error Symptom: The fuse in the new drum cartridge does not disconnect when set the new drum cartridge. Suggested corrective action: 1.
4.16 LCD Failure Symptom: No display in the LCD. Suggested corrective action: 1. Verify that the power cord is correctly connected and the power switch is ON. 2. Check for a blown fuse or open circuit on the unit’s internal power supply. 3. Check the DC output voltages from the power supply unit to connector P10 on the main control PCB. If any of the following voltages are incorrect, replace the power supply.
4.18 Cleaning the Unit Use a mild cleaning solution on a lint-free cloth to wipe the machine’s cover, handset and paper cassette tray. Never spray cleaner directly onto the fax machine as the spray could damage components inside the fax. Curing frequent jams in the ADF If you’re having trouble with getting your original documents to feed properly, try this procedure: 1. Turn off your fax machine. 2.
Cleaning the FBS glass, Contact glass and white pad 1. Open the platen cover. 2. Get a soft, lint-free cloth and moisten it with isopropyl alcohol. Important: Make sure the cloth doesn’t have any rough areas. Otherwise, it could scratch the glass surface of the FBS. 3. Using the cloth, gently clean the FBS glass, contact glass and the white background area on the underside of the platen cover.
