Abstract

Many xerographic cleaning products employ a radial brush type cleaner subsystem. Conductive or insulative type brushes are typically used. Two failure modes which limit the performance of these brush types cleaners are fiber set and radial shrinkage. Fiber set occurs when the copier is in a static mode, for example, the cleaner brush has a specific interference interaction with a photoreceptor in order to effectively clean the photoreceptor clean. When the copier is idled, the brush fibers are deflected for a given length of time thus causing the fiber pile height to flatten or set. Radial shrinkage is similar, but occurs in a dynamic mode. Rotating the cleaner brush at high speeds for long periods causes the brush fibers to lay down or flatten, thus reducing the brush diameter and thereby reducing the brush to photoreceptor interference interaction. Both of these failures result in poor cleaning performance.
