ABSTRACT:
An optical media detector, for use in a media transport mechanism, the detector comprising a light source and an optical sensor, is described. The light source and sensor are optically coupled via two distinct optical paths which are formed in part by a pair of optical light guides, each of which is formed into part of a pinch roller adapted to contact or being close to contacting media being transported.
