Abstract

Conventional cleaning apparatus 3 for cleaning toner off photoreceptor 5 in an electrostatic reproduction machine is shown in Figure 1. The photoreceptor 5 moving in the process direction depicted by arrow 7 is cleaned first by rotating brush 10. Brush 10 disturbs residual toner 12 to reduce high toner densities and remove contaminates from the photoreceptor. Flicker bar 14 flicks toner from brush 10 and with the aid of an air flow traveling laterally (the length of brush 10) exists through exhaust 15. Airborne toner loosened by brush 10 and flicker bar 14 accumulates in a waste bottle (not shown) attached to exhaust 15. Photoreceptor 5 is further cleaned from toner by multi-blade assembly 17.

BLADE CLEANERS WITH AIR DISTURBERS (Cont'd)

Conventional cleaning apparatus 3 for cleaning toner off photoreceptor 5 in an electrostatic reproduction machine is shown in Figure 1. The photoreceptor 5 moving in the process direction depicted by arrow 7 is cleaned first by rotating brush 10. Brush 10 disturbs residual toner 12 to reduce high toner densities and remove contaminates from the photoreceptor. Flicker bar 14 flicks toner from brush 10 and with the aid of an air flow traveling laterally (the length of brush 10) exists through exhaust 15. Airborne toner loosened by brush 10 and flicker bar 14 accumulates in a waste bottle (not shown) attached to exhaust
15. Photoreceptor 5 is further cleaned from toner by multi-blade assembly 17.

Similarly, an air flow travels laterally and exits through exhaust 18 to remove toner from the bottom of each blade's cleaning edge.

Disclosed is cleaning apparatus 20 shown in Figure 2 that injects high velocity air to disturb residual toner in place of disturber brush 10 shown in Figure 1. The high velocity air generated by high pressure air chamber 21 is injected normal to the blade or parallel to the photoreceptor surface as s...
