SYSTEMS AND METHODS FOR CLEANING BIAS CHARGE ROLL SURFACE IN PRINTING SYSTEMS

摘要

A vibration-assisted bias charge roll cleaning system includes a bias charge roll cleaning member connected to an actuator for causing the cleaning member to vibrate. The actuator is controlled to vibrate according to a predetermined pattern, and at desired frequencies at particular modes. The cleaning member is configured to be movable to a contact-cleaning position and a cleaning member cleaning position at which the cleaning member is separate from the charge roll.
