Abstract: An electro-optic printer of the type having a laser, a modulator for modulating the laser beam in accordance with image signals; an optical system including a rotating polygon for sweeping the modulated beam across the photosensitive drum of a xerographic system to expose the drum and create images thereon, the modulator having a plurality of separately controlled electrode groups effective to modulate portions of the laser beam in accordance with individual lines of image signals to enable multiple image lines to be exposed at once on the photosensitive drum; and a step drive to synchronously step the photosensitive drum in increments equal to the combined width of the lines being processed. In a first alternate embodiment, the modulator is based on a wave guide, and in a second alternate embodiment, the modulator is composed of a series of flexible reflective fingers.

Abstract: A multi-mode reproduction machine or copier incorporating a full width read/write bar having at least one linear array of LEDs for selectively scanning a document original in a read mode or exposing the copier photoreceptor in a write mode. An array of lens elements is provided for focusing the LED array on both the document original and the photoreceptor, the read/write bar and lens array being combined in a unitary structure selectively movable between read and write positions. In an alternate embodiment the read/write bar and lens array is disposed in a fixed position to permit selective reading of the image developed on the photoreceptor or writing of images onto the photoreceptor.

Abstract: The present invention is a system for utilizing a printable, yet unobtrusive glyph or similar two-dimensionally encoded mark to identify copyrighted documents. Upon attempting to reproduce such a document, the glyph is detected, decoded and used to accurately collect and/or record a copyright royalty for the reproduction of the document, or to prevent such reproduction. Furthermore, the glyph may also include additional information so as to enable an electronic copyright royalty accounting system, capable of interpreting the encoded information, to track and/or account for copyright royalties which accrue during reproduction of all or portions of the original document.
