Abstract
A method for moving a media sheet within an imaging device includes moving a media sheet along a media path by rotating an at least one roller. While the media sheet is moving, a first sensor is activated with the media sheet and then a second sensor is activated with the media sheet. Feedback is received by a processor indicating the number of rotations of the at least one roller. A measured distance DM from the first sensor to the second sensor is calculated. An adjusted distance DA from the second sensor to a feed nip is then calculated. After activation of the second sensor, the roller continues to move the media sheet on the media path and the roller is rotated at least the adjusted distance DA. The media sheet then enters into the feed nip in a substantially deskewed alignment.
