ABSTRACT:
A device that improves the effectiveness of a corona charging element cleaner by forcing it to travel to the end-limits of the outboard end of the corona charging element to ensure that the corona charging element is completely wiped clean. The device uses a pawl and rack to affect a ratchet-like motion, the direction of which permits travel in the opposite direction only after the limit of travel is reached.
