PCR- Printer & Copier Primary Charge Roller - Universal Compatible Charging Roller For Imaging System

Primary Charge Roller

Primary Charging Roller (PCR) for copier drum units

As the "charge source" of the electrostatic imaging system, the PCR applies rated electric charge evenly to the surface of the OPC drum through its conductive rubber layer, forming uniform electrostatic potential on the drum surface and laying a foundation for subsequent laser exposure and electrostatic latent image formation.


Structure & Performance: 

Composed of a high-strength carbon steel shaft, special conductive rubber with superior wear resistance and high resilience, and an insulating protective layer. Its surface resistance is evenly controllable with outstanding charge uniformity and environmental stability. It can operate stably for a long time under high voltage and dusty conditions without potential attenuation or surface contamination.


Impact: 

The performance of the primary charging roller directly affects print density and background haze control. Aging or contamination will lead to faint prints, heavy background fog and uneven images.
