Abstract

A photoreceptor cleaner for use in a xerographic printing machine having improved performance is disclosed and shown in detail in Figures 1 and 2. The cleaner comprises a rubber roll 4 with tightly packed thin blades 6 that are approximately 0.02 to 0.05 inches thick. Multiple thinly sliced blades 6 clean the surface of photoreceptor 8 simultaneously while slowly rotating in the opposite direction of the photoreceptor surface. Figure 2 shows in detail how the individual edges of blades 6, the front face, the cut face and the back face, clean photoreceptor 8 in areas 10, 11 and 12 respectively. Because the blades are thin, the multiple edges of the thin blades continuously contact the photoreceptor surface being cleaned. Multiple blades in contact at a given time with the surface 8 insures effective cleaning with less stress applied to the photoreceptor than cleaners with only one or two cleaning blades. Additionally, multiple blades insures that proper cleaning angles of the blades are maintained along with blade rigidness since each blade supports each other in a tightly packed space around the rubber roll 4.
