摘要： A device and method for determining and applying a transfer voltage in an imaging apparatus is provided. A servo voltage is determined based in part upon a change in an environmental condition. A determination is made whether or not to perform a new transfer servo operation based upon at least one of an amount of time passing since the last transfer servo operation was performed and a comparison of the determined servo voltage and a servo voltage used in a prior transfer servo operation. A transfer servo operation includes charging a photoconductive drum to a charge corresponding to a printing voltage.

摘要： The present application is directed to devices and methods for removing toner from a belt within an image forming apparatus. In one embodiment, the device includes a housing that forms an enclosed interior space. The housing may include an inlet that leads into the interior space. A blade may be positioned in proximity to the inlet to remove the toner from the belt and direct it into the inlet. An auger may be rotationally positioned within the interior space to move the toner along a longitudinal width of the device. An agitating member may be rotationally positioned within the interior space to move the toner from the inlet towards the auger. The agitating member may include a flexible arm that contacts against at least one of the blade and the auger during rotation.

摘要： In a method of operating an inkjet printer, an intermediate transfer member is movable in an advance direction. A carrier supports a printhead, and is movable relative to the intermediate transfer member in a direction generally perpendicular to the advance direction. The printhead defines a plurality of raster lines extending over the intermediate transfer member at a non-perpendicular, fixed angle vector relative to the advanced direction. A bitmap image is defined which corresponds to an image to be formed on the intermediate transfer member. The bitmap image includes a plurality of rows and columns of pixels, with at least one image data corresponding to each pixel. The bitmap image is skewed such that the image data for at least one column within the bitmap image is shifted a predetermined number of pixel locations, dependent upon the fixed angle vector.

摘要： A printhead carrier assembly in an ink jet printer includes a carrier moving along a linear path. At least one rotatable bearing is attached to the carrier. The at least one rotatable bearing has at least one axis of rotation. A rotatable shaft has a surface in contact with the at least one bearing such that the shaft is nonparallel to the at least one axis of rotation of the at least one rotatable bearing. The shaft is substantially parallel to the linear path of the carrier. Rotation of the shaft causes the at least one rotatable bearing to roll along a helical path on the surface of the shaft to thereby carry the carrier along the linear path.

摘要： An image forming apparatus includes a plurality of photoconductive drums, each photoconductive drum transferring a portion of a toner image to an intermediate transfer member. The photoconductive drums are individually rotated to a printing speed such that a downstream photoconductive drum starts rotating prior to an adjacent upstream photoconductive drum starts image transfer. Similarly, an upstream photoconductive drum starts deceleration when its following downstream station has transferred image.

摘要： An intermediate toner transfer belt includes an endless member made of a layer of a material having an endless functional surface adapted to transfer a toner image. The layer of material is textured so as to define a multiplicity of protruding portions of the material spaced apart from each other and integral with and extending outwardly from a remaining base portion of the material. The protruding portions have outer tips spaced apart from one another with outer surfaces thereon also spaced apart from one another such that the endless surface of the endless member is formed by the spaced apart outer surfaces of the outer tips of the protruding portions of the material. Further, the protruding portions are irregular in pattern and shape relative to one another and generally undulate toward and away from the remaining base portion of the material.

摘要： A layered intermediate used in inkjet printing contains a release coat formed on a transfer medium in an area where an image has not been printed. The release coat is formed of polyvinyl pyrrolidone (PVP) or a PVP copolymer and at least one solvent selected from the group consisting of glycol solvents and diol solvents. A viscous coating of PVP or the PVP copolymer is formed on the transfer medium in an area where an image has been printed. A release layer formed from components in the release coat and components in the ink is formed on the viscous coating. A first ink layer is formed on the release layer of flocculated ink. A second ink layer is formed on the first ink layer, of ink that is substantially not flocculated.
