    摘要: An apparatus for scanning a document comprises a platen for supporting at least a portion of the document; a light source; and an optical element for directing light from the light source to the platen. The optical element defines a plurality of small planar surfaces, the small planar surfaces being arranged in a linear array. Light emanating from a source is reflected from one of the small planar surfaces and emerges substantially perpendicular to an exit surface.

    摘要: A document illuminator comprising a light-transmissive element having an embedded side emitting LED fitted in a cavity formed therein. The light-transmissive element is formed with one or more optical notches and is totally encased in a white surround to yield total internal reflection of the light rays emanating from the LED. The reflected light rays are collected at an aperture which in turn transmits high power and highly uniform illumination profile to illuminate a document.

    摘要: Processes are presented for creating electronic banding compensation profiles for raster output scanner (ROS) devices by printing and scanning a test pattern having a series of strips extending along a process direction and spaced from one another along a cross process (fast scan) direction, analyzing the scanned data to determine facet-specific banding errors corresponding to individual strips, and selectively adjusting banding correction profiles to counteract the banding errors.

    摘要: A scanner includes an illuminator and a platen adapted to support a document to be scanned. A light source directs light into the platen and the light is reflected internally within the platen. A movable light sensor is positioned adjacent the platen. Liquid crystal sections between the document and the light sensor cause a zone of light to pass from the platen to the document, thereby illuminating only a portion of the document.
