  • Page 75: Paper Eject

    CHAPTER 3 THEORY OF OPERATION 2.2.3 Paper eject After the printing image on the photosensitive drum is transferred onto the paper, the paper is fed to the fixing unit to fix unfixed toner onto the paper. Afterwards, the paper is ejected from the fixing unit by the first eject roller in the fixing unit. The eject sensor lever detects whether the paper is ejected correctly or not.

    CHAPTER 3 THEORY OF OPERATION Sensors 2.3.1 Cover sensors A and B Detect opening and closing of the front cover. Cover sensor (B) Cover sensor (A) Fig. 3-32 2.3.2 Toner sensor Detects if there is toner in the toner cartridge. The toner sensor at the left side emits light through the window on the left side of the toner cartridge, then the toner sensor at the right side receives it when the toner is low.
  • Page 77: Toner Cartridge

    CHAPTER 3 THEORY OF OPERATION Drum Unit 2.4.1 Photosensitive drum Generates the latent electrostatic image and develops the image on the drum surface. 2.4.2 Primary charger Forms a uniform charge on the drum surface. (1) Corona wire Generates the ion charge on the drum. (2) Grid Spreads the ion charge evenly over the drum surface.
  • Page 78: Exposure Stage

    CHAPTER 3 THEORY OF OPERATION Print Process 2.6.1 Charging The drum is charged to approximately 870V by an ion charge which is generated by the primary charger. The charge is generated by ionization of the corona wire, which has a DC bias from the high-voltage power supply applied to it.
  • Page 79 CHAPTER 3 THEORY OF OPERATION The area exposed to the laser beam is the image to be printed. The surface potential of the exposed area is reduced, forming the electrostatic image to be printed. 1 Cycle of drum Primary charging Laser beam exposure and developing (a) Unexposed area +870...
  • Page 80: Fixing Stage

    CHAPTER 3 THEORY OF OPERATION 2.6.4 Transfer (1) Transfer process After the drum has been charged and exposed, and has received a developed image, the toner formed is transferred onto the paper by applying a negative charge to the back of the paper.
