Abstract

See full text

A system is described for tracking a position of a receiver medium as it travels along a media path. A heat source provides heat to the receiver medium in a localized area sufficient to permanently deform the receiver medium to form a reference mark. A light source illuminates the receiver medium, and a sensor is used to sense light from the light source that is transmitted through the receiver medium or reflected from the receiver medium thereby providing a sensed light level signal. The sensed light level signal is analyzed to determine a position of the receiver medium by detecting a change in the sensed light level signal that is characteristic of the physical deformation associated with the reference mark.
