  • Publication number: 20140064812
    Abstract: A pair of opposing rollers comprises a first roller and a second roller contacting the first roller to form a nip between the rollers through which print media passes. Because of surface irregularities in the rollers, the nip can have one or more unintended gaps at locations where the surface of the first roller separates from the surface second roller. Further, a frame holds the first roller and the second roller. A manual or automatic axis adjuster is operatively connected to the controller and the first roller. The axis adjuster changes the angle of the axis (a first axis) of the first roller relative to the axis (a second axis) of the second roller based on the gap to position the first axis in a position other than parallel to the second axis. Changing the angle of the first axis relative to the second axis reduces or eliminates the gap.

  • Patent number: 8643685
    Abstract: Systems and methods are described that facilitate eliminating a need for a raster output scanner (ROS) or laser when generating a latent image on a photoreceptor. An addressable backplane is employed, comprising an array of field effect transistors (e.g., silicon or organic thin film transistors, or TFTs), wherein each TFT corresponds to a single pixel on a charge transport layer on the photoreceptor surface. Latent image formation is performed by forming a surface potential using corona charging, and then directing free charge carriers toward the photoreceptor surface to reduce electrostatic potential in areas that need to be toned. TFTs in the array are individually addressed, or selected, to connect to a common ground, which allows photodischarge to occur only in selected areas (e.g., pixels associated with the selected TFTs).

  • Publication number: 20130343782
    Abstract: There is described an applicator for use in an image forming apparatus. The applicator includes an applicator comprising an elastomeric matrix and a functional material dispersed therein. The applicator includes an actuator for moving the applicator between a first position having the applicator in contact with a surface, and a second position. The actuator moves the applicator from the first position to the second position at a frequency of from about 10?5 Hz to about 10 kHz wherein the functional material diffuses from the elastomeric matrix to the surface.
