2. 4 4 FS 600 FS 680 Charging the drum Figure below is a simplified diagram for explaining how the drum is electrically charged The roller charging system that gives electrical charge on the photoconductive drum using an electroconductive rubber roller is used The rubber roller is pressed against the drum by means of the pressure given by coil springs and rotates following the drum s revolution The axle of the rubber roller is connected to the high voltage power supply via the electrically conductive resin axle holder The rubber roller is thus supplied with the AC bised DC voltage for charging the drum The OPC material needs to be negatively charged so as to function as a photo conductor The negative DC is therefore used for the charging high voltage bias The surface of the rubber roller is delicate and should not be touched by hand Charger roller 680V DC 1 8kV 380Hz AC Drum surface potential Vo 680V 25V 4 5 FS 600 FS 680 The diagram below is to explain how the DC bias is weighted by AC Note that the bias is increased to erase the residual latent image while the paper does not exists below the drum unit Main motor activation Paper length l l ookv l 1 8 kVp p 380 Hz ov 0 9 kV 1 8 kV 4 6 FS 600 FS 680 Exposure The exposure process is done by emitting the laser light onto the photoconductive drum The laser light 780 nm wavelength beam is dispersed by scanning use of
