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.
  • Page 3 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.
  • Page 4 1.6. PERSONAL SAFETY PRECAUTIONS 1.6.1. MOVING SECTIONS OF THE UNIT Be careful not to let your hair, clothes, fingers, accessories, etc., become caught in any moving sections of the unit. The moving sections of the unit are the rollers and a gear. There is a separation roller and a document feed roller which are rotated by the document feed motor.

  • Page 91 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).
  • Page 92 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 DIGITAL BLOCK DIAGRAM The ASIC (IC604) controls all the other digital ICs.
  • Page 93 Normal Wave Patterns Remarks: For these reasons and the software sequence to boot up the unit, if you use an oscilloscope the judge whether a signal is OK or NG, you must check in the same order as in [List 1]. (IF the ASIC failed to access the ROM, the ASIC cannot access G/A or DRAM normally.) The digital circuit actually operates according to the timing combinations of these signals.
  • Page 94 Accordingly, the problem presented here is whether each IC outputs the correct signal. (See the I/O direction diagram on the next page.) In other words, is it constantly switching between 3.3 V (H) and 0 V (L) as described earlier. Note: All you have to do is check that the IC repeatedly outputs (H) 3.3 V and (L) 0 V.

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.

  • Page 162 6.4. LASER SCANNING UNIT LOCATIONS 6.5. DEVELOPING AND TRANSCRIPTION The developing is the stage that the OPC drum with an invisible image is changed to visible by the toner. The developer consists of mixing paddle, toner supply roller, developing roller, developing blade and OPC drum.
  • Page 163 The values of developing bias and supply bias are different from the ones described in the Service Manual for FL501. The biases output from the unit of FL501 and FLM551 have the same voltage. However, the developing device of FA77D converts the developing and supply biases inside the developing device to improve the image quality.
  • Page 164 6.6. CLEANING 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.
  • Page 165 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.

[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.
  • Page 240 [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, ] ().
