  • Page 4: Safety Information

    SAFETY INFORMATION Laser Safety (110-120V Model only) This printer is certified as a Class 1 laser product under the US Department of Health and Human Services (DHHS) Radiation Performance Standard according to the Radiation Control for Health and Safety Act of 1968. This means that the printer does not produce hazardous laser radiation. Since radiation emitted inside the printer is completely confined within the protective housings and external covers, the laser beam cannot escape from the machine during any phase of user operation.

  • Page 33: Mechanisms

    MECHANISMS The machine is classified into the following mechanisms: n SCANNER MECHANISM - ADF mechanism - Document scanning mechanism n LASER PRINTING MECHANISM - Paper pick-up and registration mechanism - Print process mechanism (consisting of charging, exposing, developing, and transferring processes) with paper feeding mechanism - Heat-fixing mechanism with paper feeding mechanism...

  • Page 34: Scanner Mechanism

    Scanner Mechanism This mechanism consists of the following: - document tray ASSY which consists of a document chute and document tray, - automatic document feeder (ADF) unit which consists of a document feed roller ASSY, document ejection roller ASSY, ADF motor, and document front and rear sensors, and - scanner unit which consists of a scanner top cover, CCD unit, CCD drive mechanism, CCD HP sensor, and scanner base.
  • Page 35 This scanner mechanism supports a dual scanning system. (1) If you set documents with their faces up on the document chute and start the scanning operation, the ADF motor rotates so that the document feed roller ASSY feeds those documents into the ADF unit, starting from the top sheet to the bottom, page by page. Each document curves downwards and turns to the right so as to advance above the CCD unit, and then it is fed out to the document tray with the document ejection roller ASSY.

    Laser Printing Mechanism 2.2.1 Paper pick-up and registration mechanism III - 5...

  • Page 37: Print Process Mechanism

    At the 1st stage, the controller drives the main motor without energizing the solenoid so that the paper feed roller simply idles. At the 2nd stage, the controller energizes the solenoid so that the paper feed roller no longer rotates and the paper pick-up roller starts rotating to pick up paper into the machine, a sheet at a time.
  • Page 38 The print process unit works with laser beam, electrical charges, and toner. The graph below shows the transition of electrical charge on the surface of the laser-sensitive drum through the four processes: charging, exposing, developing, and transferring processes. III - 7...

  • Page 39: Heat-Fixing Mechanism

    2.2.3 Heat-fixing mechanism As the paper passes between the heater roller and the pressure roller in the heat-fixing unit, the heater roller fuses the toner on the paper. The controller monitors the internal resistance of the heater thermistor to keep the surface temperature of the heater roller constant by turning the halogen heater lamp on and off.

  • Page 40: Paper Ejecting Mechanism

    2.2.4 Paper ejecting mechanism After the paper passes through the heat-fixing process, it will be ejected from the heat-fixing unit by the paper ejection roller. If the leading edge of the paper pushes up the actuator of the paper ejection sensor, the sensor signals the start of paper ejection.
