Photosensitive drum The special properties of the photosensitive drum allow an image to be formed on the drum surface and then transferred to paper. The drum is an aluminum cylinder coated with a layer of organicphotoconductive material (OPC) which is non-toxic. The OPC material has properties - HP LaserJet 4100 | Service Manual - Page 450
Conditioning the drum The conditioning process consists of applying a uniform negative charge on the surface of the drum with the primary charging roller. The primary charging roller is coated with conductive rubber with an AC bias applied to erase any residual charges and maintain a constant drum - HP LaserJet 4100 | Service Manual - Page 451

The BD signal is sent to the engine controller board, where it is converted to an electrical signal used to synchronize the output of video data for one sweep (two scan lines) and to diagnose problems with the laser diode or scanner motor. 112 Theory of operation EN - HP LaserJet 4100 | Service Manual - Page 452
