  • Page 63 S-C4L Training Overview OPC drum Discharge plate Transfer roller Slide 63 Overview The transfer roller is pressed against the OPC drum. The high-power supply board gives a positive charge to the transfer roller, which causes toner to be transferred from the drum to the paper. This machine uses the following two paper separation techniques: The drum’s curvature helps separate the paper.
  • Page 64 S-C4L Training Transfer Current Timing The machine has two transfer current levels: Low and High. Low level: The high voltage supply board supplies 10µA to the transfer roller before image transfer starts. This prevents the transfer roller from getting positively charged toner on the drum surface.
