摘要： Pre-polygon optics are provided which consist of a compact design such that the number of pre-polygon elements in the pre-polygon optics is reduced while achieving desired light beam characteristic. The pre-polygon optics may consist of a hybrid toroidal diffractive optical element, refractive cross-cylindrical optical elements, refractive spherical and cylindrical optical elements, a refractive sagittal cylindrical optical element or a refractive tangential cylindrical optical element. Accordingly, advantages such as lower cost and ease of alignment are achieved.

摘要： In an electronic printer which utilizes an image write bar, a control circuit is provided to compensate for the effects of vibration in a rotating photoconductive member, typically a photoreceptor drum. In one embodiment an encoder is positioned so as to detect spatial displacements of indicia affixed to the photoconductor surface, Correction signals are generated and sent to control circuits which adjust the on/off timing of the write bar operation and/or the intensity of the image bar output. This adjustment results in compensation for the effects of photoconductor vibration.

摘要： A system for concurrently imaging the first and second sides of different sequential duplex documents in alternating image lines alternating between the first and second imaging stations. This system is shown in a system for imaging both of the first and second opposing sides of duplex documents with higher productivity, with a generally "V" shaped low profile document sheet feeding path with first and second arms merging at a base position having a document reversing system, for sequentially feeding documents from an input tray through the first arm to the base position, and then back through the second arm to an output tray. A first imaging station is in the first arm for imaging the first sides of the documents, and a second imaging station is in the second arm for imaging the second sides. Both imaging stations have a simple, partially shared fixed elements optical system mounted entirely inside the document path, which can share a single electro-optical digital imager. The duplex documents are not inverted, yet are returned to the output tray in the same orientation as the stack in the overlying input tray. Compatible simplex document copying can also be provided.

摘要： A raster output scanner is capable of creating images at a wide range of selectable resolutions. A laser source for creating an image is modulated at a pixel clock rate. A clock command value is determined as a function of a value related to the pixel clock rate and a value related to a desired resolution in the fast-scan direction and a desired resolution in the slow-scan direction of an image to be created on the photosensitive surface. The pixel clock rate is controlled in response to the clock command value. A polygon command value is determined as a function of the value related to the pixel clock rate, a value related to a desired resolution in the fast-scan direction of an image to be created on the photosensitive surface, and a value related to a rotational velocity of the polygon mirror. The rotational velocity of the polygon mirror is controlled in response to the polygon command value.

摘要： An illumination housing includes a glass platen for supporting a document, the platen having at least one surface area uniformly roughened. In one embodiment, both surfaces are uniformly roughened by an etching process. The surface of the platen are thus rendered diffusely reflective to specular hot or cold light spots formed by light reflected from optical components within the illumination system and compensates for platen-derived specular reflections into the projection lens.

摘要： A two-dimensional full-frame illumination assembly is formed, in a preferred embodiment, by coupling light into the edges of a document platen which has been modified by applying a white segment pattern to the bottom platen surface. The coupled light is totally internally reflected within the platen body except for the area covered by the segment pattern. Light encountering the segments is reflected upward towards the document support surface to provide the required document illumination. The light reflected by the document passes back through the screen segment pattern and is projected by a conventional lens or a full-frame, two-dimensional, short focal length lens array onto a photosensitive surface such as a photoreceptor belt.
