Abstract
An apparatus and method for cleaning particles from a moving imaging surface. Backers are retracted from the photoreceptor to release cleaning contact between the brushes and the moving imaging surface during development of image-on-image in the multi-pass cycle. After transfer of the image, the backers move into contact with one side of the photoreceptor causing the moving imaging surface, on the other side of the photoreceptor, to contact the cleaner brushes. The brushes clean the moving imaging surface of the photoreceptor. The brushes are released from contact with the moving imaging surface when the backers are retracted, allowing the image on image multi-pass process to begin again. The brushes engage and disengage the photoreceptor in the interdocument zone (i.e. non-imaging region) of the moving surface.
