    Pickup/feed/delivery system The pickup/feed/delivery system consists of several types of feed rollers and sensors. The ECU uses two motors and two solenoids to drive the rollers. Three media-detection sensors detect media as it passes through the device. If media does not reach or pass each sensor within a specified time period, the ECU determines that a jam has occurred and alerts the formatter.

  • Page 77: Step 1: Primary Charging, Step 2: Laser Beam Exposure, Step 3: Developing

    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 4-12 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 78: Step 4: Transfer, Step 5: Separation

    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 79: Step 6: Fusing, Step 7: Drum Cleaning

    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 4-16 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.
