Abstract: PHOTOCONDUCTOR CLEANING STATIONS A photoconductor member is cleaned by a rotating fiber brush. The cleaned particles are knocked from the brush by a knock-off bar causing substantial wear on the brush. To compensate for the wear, both the knock-off bar and the fiber brush are adjusted for maintaining cleansing contact between the photoconductor member and the brush, plus the brush with the knockoff bar. In a preferred form of the invention, the fiber brush also is an air impeller for entraining cleaned particles from the photoconductor drum into a disposal station which, by way of example, may contain a scavanging roll and an air filter. The adjustments are such that the air impeller properties of the rotating brush are maintained throughout the life of the brush.
