Print Process Description Charge

In the Charge step, the surface of the drum rotates at a constant speed and is uniformly charged (negative) by the discharge of the BCR (Bias Charge Roll) in the Drum Cartridge. The BCR is always in contact with the surface of the drum, driven by the drum rotation. The BCR is a conductive roll, receiving discharge voltage from the HVPS. The discharge voltage is negative DC voltage to which AC voltage has been superimposed. The discharge occurs in the very small gap between the BCR and the drum...
