摘要： 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.

摘要： 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.

摘要： A method of calibrating once-around and harmonic errors of encoded nips is provided. An encoder with an index pulse is used to measure the velocity and rotation of the driven wheel or idler. The geometry of the drive train and wheel and idler is chosen so that their once around and harmonic frequencies are unique such that no other drive errors will generate these frequencies. The method includes running the idler or wheel at substantially constant velocity for N revolutions. Each index triggers the collection of velocity data, which is averaged for N revolutions. This process detects drive train motion errors that are periodic with respect to the timing of the index pulse (i.e., once per revolution of the wheel or idler). Once the velocity errors have been measured, corrections are made. This method may be incorporated in xerographic machines as part of a setup or calibration procedure.

摘要： An electrostatographic and/or xerographic machine includes a media path adapted to move a media sheet. Sensors are positioned adjacent the media path. The media sheet has a leading edge and a trailing edge and the sensors are adapted to identify locations of the leading edge and the trailing edge of the media sheet. A marking device is positioned adjacent the media path. The marking device is adapted to print first items on a first side of the media sheet and print second items on a second side of the media sheet. A registration controller is operatively connected to the media path and to the sensors. The registration controller determines a length between the leading edge and the trailing edge of the media sheet using output from the sensors, and determines the parallelism between the leading edge and the trailing edge of the media sheet using output from the sensors. The registration controller calculates a registration correction factor based upon the length and the parallelism and corrects the alignment of the first items printed on the first side of the media sheet with the second items printed on the second side of the media sheet using the registration correction factor.

摘要： A method of registering sheets laterally and in skew enables active sheet deskew without translating the sheet in the cross-process direction. A sensor carriage position is controlled to find the sheet edge after which deskew control can start. The average value of the carriage position can then be fed in a feedforward manner to move the image location to match the average paper position. This achieves good average lateral registration and active skew control at a reduced cost.
