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： 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： A dry time sensor apparatus for an ink jet printer includes a light source emitting light onto a selected area of ink on a print medium such that the light reflects off of the selected area of ink. A reflective device receives the reflected light and reflects the light a second time back onto the selected area of ink such that the light is reflected a third time by the selected area of ink in a predetermined direction. The predetermined direction is substantially nonvarying over a range of angles of orientation of the print medium and a range of distances of the print medium from the light source. A reflected light detecting device receives the light reflected in the predetermined direction.

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 system for tailoring a transfer nip electric field includes a transfer roll, a backup roll forming a transfer nip with the transfer roll, and a pre-nip roll positioned upstream from the transfer and backup rolls and the transfer nip such that a toner image-supporting transfer belt moving past the pre-nip, transfer and backup rolls separately makes contact with, wraps partially around, and rotates each of the rolls as a media sheet is fed into the transfer nip after first passing through a gap defined between the pre-nip and transfer rolls such that by presetting the position, geometry and charge of the pre-nip roll relative to the transfer and backup rolls and the transfer belt an electrical field at the transfer nip can be tailored for enhanced toner transfer from the transfer belt to the media sheet.
