Abstract
A device and method for aligning a media sheet moving along a media path. An amount of skew that will occur as the media sheet moves along the media path is determined based on one or more physical characteristics. Previous testing of the device indicates that media sheets having particular physical characteristics will have a known amount of skew by the time they reach a predetermined location along the media path. The media sheet is moved the known amount so the media sheet is aligned. Test data is used to determine the amount of expected misalignment of the media sheet and the amount necessary to move the media sheet back into alignment.
