    Abstract: A system and method for achieving registering of side 1 and side 2 images includes sensing marks on both sides of a web with a single IOWA sensor and relying on light transmission through paper to sense side 1 marks. Side 1, the side not facing the IOWA sensor utilizes increased contrast (black toner), mark width, and repeats in order to make effective image “show through.” The image of the marks on both sides of the sheet is compared with respect to each other and adjustments to some combination of position, timing, and image magnification are made as required.

    Abstract: 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.

    Abstract: A method compensates for changes in drop velocity of drops emitted by inkjets in a printhead of an ink jet imaging device. The method includes adjusting image data used to generate firing signals for an inkjet ejector in a printhead of an inkjet imaging device with an initial ink drop correction parameter, adjusting a portion of the adjusted image data with another ink drop correction parameter in response to the portion of the adjusted image data corresponding to a predetermined firing pattern mask, generating firing signals for the inkjet ejector from the adjusted image data, and transmitting the generated firing signals to the inkjet ejector in the printhead.

    Abstract: A system and method that enables web paper skew detection by monitoring print head motor position. An inline full width array sensor actively tracks the alignment of the print heads across the print zone and actively moves the heads to maintain alignment. If the paper starts to skew across the print zone, a color misregistration error will be detected and the print units will be moves with respect to each other to maintain alignment. The absolute position of the print heads can be monitored by tracking the steps sent to each motor to maintain alignment.

    Abstract: A method of detecting print head roll begins with the formation of a test pattern on an image receiving surface. The test pattern includes a plurality of marks arrayed across the image receiving surface in a cross-process direction with each mark in the plurality being formed by a different nozzle of a print head. The cross-process direction positions of each mark in the plurality of marks are then detected; and the detected cross-process direction positions are correlated to a print head roll value for the print head.
