5 Belt Discharging (Erase Lamp) The belt discharging process means that upon completion of the drum transfer process, an LED light is radiated onto the OPC belt prior to mechanically cleaning the belt to discharge the residual charge. (1) Structure of Erase Lamp i) The erase lamp is located as shown in Fig.4-8. ii) The light source of the erase lamp is 24 light emitting diodes (LEDs). (2) Process of Discharging (Refer to Fig.4-19.) i) Though the toner image was transferred to the transfer drum in the drum transfer process, there is still a residual charge on the OPC belt. ii) The residual charge (-VR) on the OPC belt is discharged by the radiation of the erase lamp light prior to cleaning the belt.
