Abstract
Media skew correction is performed by determining a leading edge skew value for the media and selecting a respective media model from a memory for a media type, each media model including a paired slope and an intercept. Based on the paired slope and intercept for the respective media model, differential velocity of a pair of aligned media feed rollers in a media feed mechanism is adjusted to correct a trailing edge skew for the media to within a desired operational window.
