  • Page 22: Exposure

    charging roller applies a uniform negative charge on the entire surface of the photoconductor drum to prepare to be irradiated by the laser beam. Service Tips In case that the surface of the charging roller is damaged (for example, there are notches or pits), it will cause uneven charge on the photoconductor drum, and periodic image defects may appear on the printed page.

  • Page 23: Develop

    latent images or electrostatic images. The laser beam discharges only to the surface, causing the beam to hit the photoconductor drum. This discharge creates a potential difference between the exposed area and the rest of the photoconductor drum surface. Service Tips Do not touch the surface of the photoconductor drum directly by hand.

  • Page 24: First Transfer

    When the laser exposes the photoconductor drum, the HVPS will transfer the electric charge to the developer roller, which is evenly adhered with toner. Due to the electrical charge difference between the developer roller and the photoconductor drum, the toner is attracted to the laser-exposed area on the photoconductor drum surface.

  • Page 25: Second Transfer

    When each photoconductor is developed, HVPS transmits voltage to the first transfer roller inside the transfer belt. For each color, the image on the surface of the photoconductor drum is transferred to the surface of the transfer belt through the charge difference between the surface of the photoconductor drum and the first transfer roller, which occurs during the direct surface contact between the photoconductor drum and the transfer belt.

  • Page 26: Fuser

    timing until the paper just moves to the position between the transfer belt and the second transfer roller. HVPS transmits the voltage to the second transfer roller to generate positive charge. When the image on the transfer belt reaches the second transfer roller, the negatively charged toner will stick to the paper and then the whole image is transferred from the transfer belt to the paper.
  • Page 27 With the help of transfer roller, the paper with image enters the fuser area. The fuser applies heat and pressure to the paper to melt the toner particles and stick them to the paper permanently. The fuser drives the paper to the exit roller, which then drives the paper to the paper channel. Service Tips In case that the fuser roller is damaged, toner may fall off the paper and the paper may be jammed.

  • Page 28: Cleaning/Wiping

    2.4.7 Cleaning/Wiping The printer will perform these two cleaning processes during the imaging process. During these two processes, the residual toner will be removed from the corresponding modules. a. Cleaning of transfer belt Transfer Screw belt Cleaning blade After the image is transferred to the paper by transfer belt, the cleaning blade transfers the residual toner to the waste toner bottle by the rotating screw.
