  • Patent number: 6189991
    Abstract: Ink jet printing apparatus for forming an ink image on a receiver in response to a digital image includes at least one moveable ink jet print bar which is adapted to deliver ink to the receiver at an image transfer position to print at least a portion of a line at a time across the width of the receiver. The receiver is moved along a path past the ink jet print bar at the image transfer position. A detector unit disposed adjacent to the path detects receiver skew relative to the ink jet print bar and producing a signal representative of the receiver skew. Alignment structure coupled to the print bar is responsive to the signal for adjusting the position of the print bar to compensate for receiver skew, and a control unit is responsive to the digital image after the ink jet print bar has been positioned for actuating the ink jet print bar to form an ink image on the receiver. The alignment structure may also position the print bar to change the image resolution.
