  • Optical transparency detection and discrimination in an electronic reprographic printing system
    Patent number: 5329338
    Abstract: A method and apparatus for detecting and discriminating a copy sheet in an electronic reprographic printing system has a diffuse reflective sensor disposed adjacent a portion of the path over which the copy sheet moves. The sensor is disposed so that its optical axis intersects the copy sheet where the angle of intersection between the copy sheet and the optical axis remains within a specified range of angles for the maximum length of the copy sheet. A diffuse reflective sensor is also disposed adjacent inlet baffles with its optical axis aligned so that a transparent copy sheet is not detected while an opaque copy sheet is.
