Patent ID: 8295749

Claim:
A method of controlling image to print media sheet registration in a tandem digital printing system, the method comprising: receiving a plurality of parameters for a print job; cycling up a first print engine and a second print engine, wherein the first print engine includes at least a first seamed photoreceptor belt and an output inverter and the second print engine includes at least a second seamed photoreceptor belt; calculating a seam offset for the first and second photoreceptor belts, wherein the seam offset comprises an amount of time to offset the seam of the second photoreceptor belt relative to the seam of the first photoreceptor belt; adjusting the speed of the second photoreceptor belt based on the seam offset; starting the print job; and adjusting a dwell time of the output inverter for a given sheet length based on a maximum sheet size for a given pitch mode, actual sheet size, and the speed of the sheet entering the output inverter.
