Abstract

This electrophotographic cleaning apparatus comprises a housing 10 in which a fiber cleaning brush 12 is mounted for rotation adjacent an electrophotographic plate 14. A first flicker bar 16 is mounted to contact the brush fibers to aid in removing the toner material from the brush fibers. A vacuum source is provided to exhaust the air from housing 10 through an opening 18, to carry away the dislodged toner from the cleaning assembly. A second flicker bar 20 is provided on the opposite side of brush 12 to aid in cleaning the brush. An opening 22 is provided in flicker bar 20 to direct the flow of air, as shown by the arrows, both through the fibers of the brush and around the flicker bar 20. An opening 17 is also provided in flicker bar 16 to provide a path for air to bypass the flicker bar 16.

Electrophotographic Brush Cleaner

This electrophotographic cleaning apparatus comprises a housing 10 in which a fiber cleaning brush 12 is mounted for rotation adjacent an electrophotographic plate 14. A first flicker bar 16 is mounted to contact the brush fibers to aid in removing the toner material from the brush fibers. A vacuum source is provided to exhaust the air from housing 10 through an opening 18, to carry away the dislodged toner from the cleaning assembly. A second flicker bar 20 is provided on the opposite side of brush 12 to aid in cleaning the brush. An opening 22 is provided in flicker bar 20 to direct the flow of air, as shown by the arrows, both through the fibers of the brush and around the flicker bar 20. An opening 17 is also provided in flicker bar 16 to provide a path for air to bypass the flicker bar 16.

This arrangement produces adequate cleaning when electrophotographic plate 14 is traveling at a relatively high-linear rate. If desired, a bias voltage can be provided on one or both of flicker bars 16 and 20 to further improve the cleaning operation.
