  • Apparatus for cleaning toner supply cartridge corona wire
    Patent number: 5940656
    Abstract: A cleaning assembly for polishing debris from a corona wire is disclosed. The cleaning assembly includes a seat movably mounted within a housing to slide along the length of the corona wire. The seat has a polishing element configured to deflect the corona wire from an operating position. The assembly further includes a handle protruding from the housing whereby as the handle is pulled away from the housing along a plane defined by the length of the corona wire, the polishing element deflects the corona wire and polishes the taut wire to clean the corona wire.
