    Stapler The stapler has no logic and no interaction with the formatter. The stapler is functional during the power-on cycle of the MFP as long as the power switch of the MFP is in the on position. If the MFP is in power-save mode and a user staples a document or opens the stapler door, the engine will not wake because it does not know that activity has occurred.

    Duplex feed unit This MFP performs duplex printing by turning the paper upside down. The duplex paper path is shown in the following illustration: Figure 4-13 Duplex paper path The duplex feed unit is driven by the main motor.

  • Page 90: Media-width Detection

    Media-width detection The media-width sensor automatically detects the media width for media that is 210 mm (8.27 inches) or wider. When media narrower 210 mm (8.27 inches) is fed, the media-width sensor is not activated. Because the narrow media doesn't dissipate enough heat for the fuser, a protection mechanism must be triggered to protect the fuser from overheating.

  • Page 96: Step 1: Primary Charging

    Step 1: Primary charging Dc and ac biases are applied to the primary charging roller, which transfers a uniform negative potential to the photosensitive drum. Figure 4-22 Primary charging Step 2: Laser beam exposure The laser beam scans the photosensitive drum to neutralize negative charges on parts of the drum. An electrostatic latent image is formed on the drum where negative charges were neutralized.

  • Page 97: Step 4: Transfer

    Toner acquires a negative charge through friction from the developing cylinder and the blade. When the negatively charged toner comes in contact with the drum, the toner adheres to the electrostatic latent image. The image on the drum becomes visible because of the toner. Step 4: Transfer The transfer charging roller, to which a dc positive bias is applied, imparts a positive charge on the print media.

  • Page 98: Step 6: Fusing

    Step 6: Fusing The dc negative bias applied to the fusing film strengthens the holding force of the toner on the print media and prevents the toner from scattering. Figure 4-26 Fusing Step 7: Drum cleaning The cleaning blade scrapes the residual toner off of the photosensitive drum and deposits it into the waste toner case.
