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.

Media skew correction

A media alignment calibration system determines a slope relating a trailing edge skew value to its paired leading edge skew value and an intercept representing native skew based on a linear regression of a predetermined number of a set of paired leading and trailing edge skew values for a media type stored in a buffer. Based on the slope and intercept, a media model for the media type is updated based on the linear regression to adjust a differential velocity of a pair of aligned media feed rollers in a media feed mechanism to correct both a future native skew and future paired leading and trailing edge skew values in the buffer to within a desired operational window.
