ABSTRACT:
An apparatus for detecting the presence and type of receiver media in a document production apparatus, such as a copier, thermal printer or other printing device, includes a noncontact sensor and media transport means. Media transport means transports as least two different types of receiver media along a transport path. The noncontact sensor is positioned along a sensor plane and has a light emitting member that emits light along the sensor plane towards the media, and a light detecting member that collects light reflected from the media along the sensor plane and produces a signal that is related to the amount of light collected. The presence of the signal indicates that media is present and the amount of reflected light is indicative of the type of media.
