  • Patent number: 7043187
    Abstract: A method and structure for an image processing apparatus that includes an image bearing surface adapted to receive electrostatically charged toner, a cleaning brush adapted to remove waste particles from the image bearing surface, a detone roller adapted to remove the waste particles from the cleaning brush, and a speed controller adapted to maintain a rotational speed of the cleaning brush above a minimum speed below which the waste particles would not be removed from the image bearing surface and below a maximum speed above which the waste particles would be thrown from the cleaning brush.
    Type: Grant
    Filed: February 21, 2002
    Date of Patent: May 9, 2006
    Assignee: Eastman Kodak Company

  • Patent number: 6690899
    Abstract: A conductive fur brush cleaning assembly for an image processing apparatus. The cleaning assembly has a casing, a plurality of rotating components within the casing and a plurality of sealing devices that divide the casing into a scavenging zone and a detoning zone. The sealing devices prevent airborne marking particles from traveling from the detoning zone into the scavenging zone.

  • Patent number: 6549747
    Abstract: A method and structure for a conductive fur brush cleaner assembly for an image processing apparatus is disclosed. The cleaner assembly includes a plurality of rotating components, an insulated outer cover surrounding the rotating components and a conductive inner cover surrounding the rotating components. The insulated outer cover prevents a charge from being bled from the conductive inner cover. The conductive inner cover accumulates a charge from the waste particles within the cleaner assembly such that the inner cover becomes biased.
