摘要： A printer having a color copy capability is enabled by scanning an original document having at least two discrete colored areas onto a color-filtered photosensor array simultaneously with formation of an electrostatic image of the original on a photoconductor member. The array generates output signals corresponding to detected color areas of the original document. These signals are sent to the printer software which determines the detected color image coordinates of each portion of the output copy. Output copies are then made, using multiple imaging erase and development passes.

摘要： A method for aligning printheads, some of which are arranged in an overlapped configuration, in a printer has been developed. The method includes identifying a stitch error for each color station in a plurality of color stations in the printer. The stitch error is identified with reference to shrinkage of a print medium as the print medium passes the plurality of color stations. A portion of the stitch error is used to move at least one printhead in the color station corresponding to the stitch error to compensate for a banding issue caused by the overlapped printhead configuration. All or part of the stitch error may also be applied to other printheads in the color station to compensate for possible color to color registration issues.

摘要： A method for operating an inkjet printer to form images that include both high density and low density segments has been developed. The method includes operating one printhead to eject ink drops with a large size to form high density segments of the image, and operating a second printhead to eject ink drops with a small size to form low density segments of the image. The large ink drops provide high coverage in the high density segments, and the small ink drops provide improved image quality in the low density segments of the image.

摘要： What is disclosed is a system and method for minimizing the Inter-Document Zone (IDZ) in printing system architectures with print engines running at constant speed. The asymmetric IDZ precession disclosed herein is intended for those multi-pass systems where there is a difference in required start and stop durations of various transition subsystems such as transfer engagement and disengagement processes. This mode reduces the required inter-document zone region by shifting the zone in accordance with asymmetric timing of start and stop times of processes that must occur during this time. Advantageously, productivity gains are effectuated without altering process speeds.
