  • Patent number: 5214479
    Abstract: Apparatus for cleaning residual toner and paper fiber residue from a biased transfer roll (BTR) in an electrophotographic apparatus using high velocity air and substantially contactless flexible biased conductive shims. The high velocity air flow between the BTR and two thin conductive flex-shims is created by means of a blower that evacuates the air in the cleaner housing vacuum chamber. The high velocity air, in combination with the electrically biased BTR and flex-shims, removes residue from the BTR surface and carries it into the vacuum chamber and deposits the residue in a filter bag. The BTR biased shim cleaner system is low cost, efficient and significantly smaller than current BTR cleaning devices.
