Working principle:
The PCR charges the surface of the rotating photosensitive OPC with a uniform charge. It is achieved by generating high voltage through a high-voltage power supply and sending it to the surface of the PCR to produce an electric field effect, which causes the charges on the surface coating material of the OPC to be drawn to the surface of the PCR and leaves electron holes to modulate the charges on the surface of the OPC.
The PCR produced by our company feature high charging efficiency, can achieve low-voltage charging, have a smooth surface, good straightness, precise resistance control, are environmentally friendly and pollution-free.
