<p>A method of calibrating registration of a sheet with a sheet gripper (84) on a moving transport (48). The sheet gripper (84) is adapted to move the sheet in a recirculating path in a printing machine. Movement of the sheet gripper (84) and sheet is timed from a reference time until each reaches a loading zone, as detected by a sensor (96). The times are compared to a preselected time and the movement of the sheet gripper (84) and sheet adjusted to correspond to the preselected time. In this way, the sheet and sheet gripper (84) arrive at the loading zone simultaneously.</p> |
