A method of removing media lateral DC position errors in a long paper path using closed loop correction is disclosed. The amount of lateral DC media shift error generated (or the lateral DC correction required) in the paper path is sensed by a CCD or full width array sensor located in the downstream paper path. In the closed loop, this information is used to energize a motorized actuator in the upstream paper path to correct for lateral DC errors in the media path. Thus, the paper is delivered to the downstream media path within specifications.
