    MECHANISMS The facsimile equipment is classified into the following mechanisms: n SCANNER MECHANISM - Document feeding and ejecting 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...

  • Page 31: Scanner Mechanism

    Scanner Mechanism 2.1.1 Document feeding and ejecting mechanism This mechanism consists of the document stacker, automatic document feeder (ADF), document ejection roller ASSY, and document sensors. (For details about the sensors, refer to Section 2.3.) If the operator sets documents on the document stacker and starts the scanning operation, the scanner motor rotates so that the ADF (which consists of the document take-in roller ASSY, nip- related parts, separation roller ASSY, and ADF parts) feeds those documents into the equipment, starting from the bottom sheet to the top, page by page.

  • Page 32: Laser Printing Mechanism

    Laser Printing Mechanism 2.2.1 Paper pick-up and registration 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 equipment, a sheet at a time.

  • Page 33: Print Process Mechanism

    2.2.2 Print process mechanism 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 - 5...

  • Page 34: Charging Process

    (1) Charging process The high-voltage power supply applies DC bias to the corona wire to generate ion on the grid. The ion uniformly charges the surface of the laser-sensitive drum to approx. 870V which is kept by the voltage regulator grounding the grid to the frame. (2) Exposing process When the laser-sensitive drum holds a positive electrical charge, the laser beam issued from the laser unit scans the drum according to the print image to expose the drum surface for neutralizing...

  • Page 35: Developing Process

    (3) Developing process The developing process develops an electrostatic latent image formed on the drum in the exposing process, into a toner image. The developer roller attracts the toner particles fed from the toner cartridge by the toner supply roller, and then conveys them to the contact section with the laser-sensitive drum On the contact section between the developer roller and drum, the positive toner particles stick to the neutralized spots on the drum according to the principles of attraction and repulsion, transforming a latent image into a toner image.

  • Page 36: 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 37: 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.
