摘要： A method for reducing edge effect (white gapping) between objects formed on a photoconductive member of an imaging device includes, during processing of a given color plane, under exposing (partially exposing) the photoconductive member for image data that specifies a color to be developed on at least one color plane but specifies no color to be developed on the given color plane. Under exposing occurs relative to a development threshold for the image processing of the given color plane. As such, the under exposing does not enable development of that image data during image processing of the given color plane. The under exposing occurs relative to a high frequency halftone screen for minimizing contamination (unwanted development) during the partial exposure. A half tone screen switching process enables appropriate halftone exposure for objects embodying the given color plane, and enables the necessary under exposure (utilizing the high frequency halftone screen) for objects not embodying the given color plane. By partially exposing objects that do not include a color to be developed on the color plane currently being processed, and while normally exposing adjacent objects that include a color to be developed on the current color plane, the lateral electric field effects between the objects is reduced and, thus, toner development for the given color plane is more edge precise for reduced white gapping between the objects.

摘要： This invention is concerned primarily with scanning at multiple vertical resolutions using an essentially single speed scanner (11, 12) without having to use complex digital image processing to do resolution conversions. The invention accomplishes the multiple resolution scanning by a combination of rejecting certain lines of data and making relatively small adjustments to the paper velocity, V'.sub.p.

摘要： A method for reducing edge effect (white gapping) between objects formed on a photoconductive member of an imaging device includes, during processing of a given color plane, partially exposing the photoconductive member for all image data that specifies a color to be developed on at least one color plane but that specifies no color to be developed on the given color plane. As such, the partial exposing does not enable development of that image data during image processing of the given color plane. By partially exposing objects that do not include a color to be developed on the color plane currently being processed, and while normally exposing adjacent objects that include a color to be developed on the current color plane, the lateral electric field effects between the objects is reduced and, thus, toner development for the given color plane is more edge precise for reduced white gapping between the objects.

摘要： A method of aligning duplex images on an imaging device such as a printer or copier includes duplex imaging a test sheet having indicia on each side of the sheet that communicate, when observed in a single visual context, duplex imaging adjustment parameters for the imaging device. The method further includes modifying imaging parameters of the imaging device based on the duplex imaging adjustment parameters communicated. The indicia on each side of the sheet are seen in a single visual context by observing certain of the indicia through the media, as when the media is held up to a light source. In a preferred embodiment, the indicia on each side of the sheet includes respective portions of a vernier scale. The imaging parameters are modified by entering the adjustment parameters at a control panel of the imaging device. Imaging parameters modified include timing parameters associated with the process of writing data on the imaging device. In addition to the method, an imaging device includes components, data and executable instructions necessary for implementing the above described method.
