Abstract: A method and system for insuring printing accuracy in simplex imaging or duplex imaging, including a media sheet in a media path adapted to move the media sheet through the system. The media path includes sensors and a datum. The sensors include a leading edge sensor and a trailing edge sensor adapted to record the time of arrival of the edge. The edge arrival time difference is determined between the arrival time of the edge using output from the trailing edge sensor and the arrival time of the edge using output from the leading edge sensor. A correction factor is based upon the time difference. The time of arrival of the media sheet at the datum is determined using the correction factor to align items printed on both side of the media sheet.

Abstract: A method of adjusting the operation of printheads in a printing system with a moving sheet carrying device has been developed. The method includes identifying a first amount of sheet carrying device displacement and second amount of sheet carrying device displacement as the sheet carrying device carries a media sheet past first and second printheads, respectively, for imaging of a predetermined location of the media sheet. A time for operating the second printhead is adjusted based on a difference between the first sheet carrying device offset and the second sheet carrying device offset to provide color registration between ink drops of the first printhead and second printhead on the media sheet.
