A method of document overlap/gap error detection and correction includes detecting a trailing edge of a first document at a feeder, and detecting a leading edge of a second document at an edge detector between the feeder and a transport stage. An overlap/gap error is determined and the feeder is controlled to correct the overlap/gap error, when the error is present. An overlap may be measured before the first document trailing edge arrives at the edge detector, providing a greater remaining length of the second document left in the feeder with which to perform the necessary feeder motions to correct the overlap/gap error.
