Patent ID: 7088947

Claim:
An image-forming production system, the system comprising; a marking engine that prints an image onto at least one sheet defining at least one printed sheet, the marking engine having an output which feeds the at least one printed sheet at a first speed; an inserter connected to receive the at least one printed sheet from the marking engine output, the inserter having an inserter supply that feeds an insert sheet to be placed sequentially with the printed sheet in a print job, the insert supply feeding the insert sheet to the inserter at a second speed; and an inserter speed adjust unit that sequentially receives the at least one printed sheet at the first speed and the insert sheet at the second speed and outputs both at an adjusted third speed wherein: the marking engine transmits a synch pulse signal used to indicate a nominal time when the at least one printed sheet is to arrive at the inserter speed adjust unit; the inserter speed adjust unit determines the actual arrival time of the at least one printed sheet at the inserter speed adjust unit; and the inserter speed adjust unit compares the synch pulse signal to the actual arrival time and uses the comparison to determine an adjust time when the inserter speed adjust unit changes the speed of the at least one sheet from the first speed to the third speed.
