  • Patent number: 7450869
    Abstract: Transfer component monitoring methods, image forming devices, data signals, and articles of manufacture are described. According to one aspect, a transfer component monitoring method includes counting a plurality of imaging operations performed by an image forming device to form a plurality of hard images and adjusting a result of the counting to determine wear of a transfer component of the image forming device, wherein the transfer component is configured to assist with a transfer of a developing material to form the hard images.
    Type: Grant
    Filed: December 12, 2002
    Date of Patent: November 11, 2008
    Assignee: Hewlett-Packard Development Company, L.P.
    Inventors: Carl D. Geleynse, Michael Lloyd

  • Patent number: 5640659
    Abstract: An imaging system carries an image defined by a dry powder or liquid toner. The imaging system includes a first transfer roll that electrostatically or adhesively accumulates the color image from a photoconductor, and a second transfer roll in transfixing contact with the first transfer roll. The second transfer roll possessing a central radiant heat source and a radiant heat source located adjacent to the first transfer roll in radiant proximity to an entering media sheet and the transfixing contact between the first and second transfer rolls. The first transfer roll includes at least a first basecoat layer and a topcoat layer. The basecoat layer includes a material that is electrically conductive and exhibits elastomeric and macrocompliant properties enabling the media to wrap through a significant arc under the transfixing contact and heat of the second transfer roll.

  • Patent number: 5432591
    Abstract: A liquid toner electrophotographic printer includes a movable photoconductor surface, a developer roller, a squeegee roller, a liquid toner cartridge having a supply of liquid toner and a rotatable foam roller, and a transport mechanism including a carriage and air cylinder driven actuation system. The squeegee roller is rotatably mounted on the printer for movement between a first position wherein the squeegee roller is in contact with the photoconductor surface, wherein a drip line of liquid toner forms therebetween, and a second position wherein the squeegee roller is spaced away from the photoconductor.
