    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 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

    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.
