    CHAPTER I GENERAL FEATURES This high-speed, non-impact (low-noise) printer is based on electrophotography, electronics and laser technology. The printer is compact and easy to carry. The internally-storable, front-loading paper cassette enables you to save an occupation space for the machine; the printer can now be installed in a smaller place.

    STORAGE AND HANDLING OF EP-ED HC CARTRIDGES An EP-ED HC cartridge is influenced by the storage conditions even if it is sealed in its package, so its life depends on the way in which it is used or stored. EP-ED HC cartridges should be handled carefully.
  • Page 18: Chapter Ii Theory Of Operation

    CHAPTER II THEORY OF OPERATION This chapter describes the printer functions, the relationship between the electrical systems and mechanical systems, and the timing of operations. Striped conduits ( ) indicate mechanical linkages; solid thin arrows ( appearing with a signal name indicate the transmission of single control signals and outlined thick arrows ( ) indicate the transmission of groups of signals.
  • Page 19: Main Drive

    Main Drive The power necessary for driving the printer is supplied by the main motor, the paper feed motor and the laser unit motor. The main motor is controlled by the main motor drive signal (MDRIVE) output from the main PCB, and the paper feed motor is controlled by the paper feed motor drive signal output from the main PCB, and the laser unit motor is controlled by the laser unit motor drive signal (SDRIVE) output from the main PCB.

  • Page 22: Image Formation System

    IMAGE FORMATION SYSTEM Outline The image formation system is the main part of the printer. The print information, after input from the video controller circuit into the engine controller circuit as a TVDO signal, forms a toner image on the photosensitive drum. Then the toner image is transferred onto the paper by the transfer charging roller.

  • Page 24 Step 1 Primary charge Primary charging roller AC bias Photosensitive drum DC bias Figure 2.9 As preparation for latent image formation, a uniform negative potential is applied to the photosensitive drum surface. The printer uses the charging method that directly charges the drum for the primary charge.

  • Page 26 3.2.3 Transfer stage In the transfer stage, the toner image is transferred from the drum surface to the paper. Step 4 Transfer Photo- sensitive Paper drum Transfer charging roller Figure 2.13 A positive charge applied to the back of the paper attracts the negatively charged toner particles to the paper.
  • Page 27 3.2.4 Fixing stage The toner image transferred to the paper in the transfer stage is held only by electrostatic attraction and slight physical adhesion, so even a light touch will smear the image. In the fixing stage, the toner image is fixed by heating the paper and applying pressure. This fuses the toner particles to the paper to make a permanent image.
  • Page 28: Operation

    Operation When the engine controller circuit receives a print signal (PRINT) or a pre-feed signal (PRFD) from the video controller circuit, the engine controller circuit drives the main motor to rotate the photosensitive drum. After the drum surface is charged negatively by the primary charge roller, the laser beam modulated by a DATA signal scans the drum surface to from a latent image on the drum.
  • Page 29: Paper Pick-up/feed System

    PAPER PICK-UP/FEED SYSTEM Outline If a tray1 paper pick-up roller solenoid drive signal (PUCL1) is input to the circuit while the paper feed motor is rotating, the paper pick-up solenoid comes on and the paper pick-up roller solenoid is engaged. As a result, the paper pick-up roller rotates to feed paper down to the photosensitive drum.
  • Page 30: Cassette Feed

    Cassette Feed When the fixing rollers reach the specified temperature while a cassette with paper is in the printer, the READY lamp changes from flashing to lighting. When the engine controller circuit receives PRNT or PRFD signal from the video controller circuit, the paper feed motor starts rotation.
  • Page 31: Mp Tray Feed

    MP Tray Feed The timing of the MP tray feed is identical to the timing of the cassette paper feed except for the following points: The paper empty sensors are different. Cassette feed : Tray1 paper empty sensor MP tray feed : MP tray paper empty sensor The pick-up roller solenoids are different.
  • Page 32: Paper Jam Detection

    Paper Jam Detection The printer has a registration sensor and a paper eject sensor at the paper outlet to detect whether the printed paper has been fed correctly. A paper jam is detected by whether the paper is present at the sensor at the check periods programmed in the engine CPU memory.

    CHAPTER III ELECTRICAL SYSTEM Electric signal levels are expressed by “High” (approximate the supply voltage) or “Low” (approximate 0V). Signals with hyphen or slash, such as -FSRD or FSRD/, are low-active and signals without hyphen or slash, such as FSRD, are high-active signals.
