  • Page 33 DP1200/1500 Semiconductor laser (2) Outline of print process This printer is a non-impact printer that uses a semiconductor laser and electrostatic print process. This printer uses an OPC (Organic Photo Conductor) for its photoconductive material. First, voltage from the main corona unit charges the drum sur- face and a latent image is formed on the drum surface using a laser beam.
  • Page 34 DP1200/1500 Step-7: Optical discharge (Semiconductor laser) Non-image area Before the drum rotation is stopped, the semiconductor laser is -600 radiated onto the drum to reduce the electrical resistance in the OPC layer and elimate residual charge, providing a uniform state to the drum surface for the next page to be printed.
  • Page 35 DP1200/1500 Start 1) Because the grid potential is at a low level, the drum poten- tial is at about –400V. (Carrier may not be attracted though the carrier is pulled towards the drum by the electrostatic force of –400V. 2) Developing bias ( –400V) is applied when the photoconduc- tor potential is switched from LOW to HIGH.
