Abstract

A brush cleaner for removing leftover toner from the surface of a photoreceptor 5 following transfer of the developed image to a copy sheet is disclosed. A brush 6 is rotatably supported in an evacuated housing 7. Cooperating vacuum nozzle 10 and flicker bar 9 are disposed in close proximity to the dirty side of brush 6, nozzle 10 being coupled to a source of vacuum via conduit 8. Flicker bar 9 is supported so as to engage the periphery of brush 6 to remove by flicking action toner particles carried by the fibers of brush 6.

A brush cleaner for removing leftover toner from the surface of a photoreceptor 5 following transfer of the developed image to a copy sheet is disclosed. A brush 6 is rotatably supported in an evacuated housing 7. Cooperating vacuum nozzle 10 and flicker bar 9 are disposed in close proximity to the dirty side of brush 6, nozzle 10 being coupled to a source of vacuum via conduit 8. Flicker bar 9 is supported so as to engage the periphery of brush 6 to remove by flicking action toner particles carried by the fibers of brush 6.

In use, toner particles leftover on photoreceptor 5 are removed by brush 6. As the brush fibers move against flicker bar 9, particles carried in the fibers of brush 6 are dislodged into the vacuum-induced air stream in the nozzle-like structure 10 and are drawn from there into conduit 8. The close proximity of nozzle 10 and flicker bar 9 to the dirty side of brush 6 effects immediate removal of toner particles from the brush. At the same time the vacuuminduced air flow is directed away from the brush pile to avoid drawing airbourne toner particles through the brush. This keeps brush 6 cleaner and increases system longevity.

As an option, an air knife may be added to cushion the brush fibers from impact with flicker bar 9.
