CHARGE 2.1 OVERVIEW [A] [B] Charge/ Grid Power Pack Charge Grid This model uses a single wire corona unit [A] to it by the charge/grid power pack. A163 2-3 SM The corona unit generates a corona of negative ions when a high negative voltage is installed on the charge corona unit between the corona wire and the drum. 2. To make the negative corona uniform, a grid consisting of the charge potential. This grid drains off any charge in excess of --860 volts, thus preventing fluctuation of 8 wires is applied to charge the OPC (organic photoconductor) drum [B].
