Abstract
In one embodiment, a media is advanced in the process direction to cause a plurality of fiducials to successively appear within a sensor's focal width. Each fiducial includes a target and a background, with the target superimposed to the background. Each target has a substantially same target width, a substantially same optical density, and a position at a distinct distance from an edge of the media. Each background has an optical density less than the optical density of the targets and greater than an optical density of the media. An optical density for each fiducial is read utilizing the sensor. The target the sensor is most aligned with is discerned by identifying an identified fiducial with the highest-read optical density. Utilizing data indicative of a position of the discerned target relative to a desired position, the sensor is caused to move to the desired position.
