摘要:
A system is described for tracking a position of a receiver medium as it travels along a media path. A laser provides heat to the receiver medium in a localized area sufficient to permanently alter a physical property of the receiver medium thereby forming a reference mark. A sensor at a downstream position along the media path is adapted to sense the reference mark providing a sensed signal. The sensed signal is analyzed to determine a position of the receiver medium as the receiver medium passes through the second position along the media path by detecting a position of the reference mark.
