  • Page 31: Original Detection

    Document insert section / separator section The machine scans up to letter paper size document width. Place the document to the center of the document tray and align the document guide. By pressing the start key through copy or transmission commands, the motor starts driving, and the driving force is transferred to the pick up roller through gears, and the document will be fed.
  • Page 32 2.1.2 Flat Bed Scannser (FBS) section The FBS (Flat Bed Scanner) section consists of document glass (pane), optical reading section, scan- ner frame Assy, and scanner driving section. A lamp (White light LED array) is on the scanner frame, and the light reflected from the document passes through four mirrors and a lends to form a reduced image on CCD sensor as the scanner motor moves the scanner.
  • Page 33 Exposure Section: Construction and Function 1 Reflector tape The reflector tape reflects the light from the exposure lamp and supplements its illumination. This helps to lighten the shadow that is made when copying a document not touching the document glass such as a opened book. 2 Exposure lamp A white LED array is used to illuminate the document.

  • Page 34: Recording Section

    2.2 Recording Section 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 fed along the paper guide until it reaches the register roller. Then it is fed by the rotation of the register roller.
  • Page 35 Finisher mechanism When finishing the printouts using the shift sort function, every second set of printout will be shifted 1 inch off to the horizontal direction of paper and ejected on the tray. Paper exit direction Shift direction (1 inch) When the trailing edge of paper is nipped only by exit roller pair, the shift motor drives, and the exit roller pair will be shifted to the shift position.

Cleaning Drum charging Fusing Cleaning Exposure Drum Eraser Lamp Image transfer Development 2.3.1 Drum Charge The Drum is charged with corona discharge before LED exposure.

  • Page 37: Developing Roller

    2.3.3 Development Toner is applied to the invisible static image on the Drum and a toner image is created on the surface. Toner agitator Drum Developing roller Toner supply roller Part Name Function Toner Agitator Agitates toner. Transports the toner to the developing roller. Toner supply Roller Developing Roller Carries the toner to the Drum surface for development.
  • Page 38 2.3.5 Erasing An LED lamp exposes the Drum surface. When it is exposed the drum charge erases. This helps the drum to be recharged evenly at the next step of charging. Drum LED Lamp 2.3.6 Cleaning The residual toner or paper dust must be removed from the drum. Paper dust is removed from the drum surface by a rubber roller.
  • Page 39 2.3.7 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.
  • Page 40 Fusing Temperature Control Circuit The Thermistor detects the surface temperature of the Heater Roller and inputs that analog voltage into the Main Control PCB. Corresponding to this data, the Heater Lamp ON/OFF signal is output to the Heater ON/OFF switch of the power supply unit, causing the Heater Lamp to turn ON or OFF to control the fusing temperature.
