Abstract
An image capture system including a platen for receiving a media sheet bearing an image to be captured; an illumination system for illuminating the media sheet; a mirror disposed in optical communication with the platen, for reflecting light from the illumination system reflected from the media sheet; and an optical sensor for receiving the light reflected by the mirror. The interrelationship between the platen, mirror and optical sensor is such that a location of a top edge of the mirror's primary reflection projected onto the platen is lower than a location of a bottom edge of the image's secondary reflection projected onto the platen. In this way, the image captured by the optical sensor is free of secondary reflections.
