摘要： An image bar printing system, which, in a preferred embodiment, utilizes a plurality of LED arrays to provide a plurality of color images. The print bars are used in conjunction with a plurality of gradient index lens arrays which optically couple and focus the LED outputs onto a photosensitive surface. In order to maintain image-to-image registration, out of spec deviations in active write length of the image bar and scan line bow are identified and compensated for by selective deformation of one or more lens arrays in a specified manner. The lens deformation serves to reorient the position of certain of the lens elements, redirecting the transmitted LED outputs so as to shorten or lengthen the active write length, or to eliminate bow in the scan line.

摘要： The invention is directed to a document reproduction system which includes an improved apparatus for imaging both sides of a duplex document while also providing for simplex side only imaging. A document feeder, operating in a constant velocity transport mode, moves a document to be copied along a continuous path from a feed tray to a deposit tray. Two illumination and scanning stations are positioned adjacent two locations of the path of the document travel, each scanning station adapted to scan one side of the document, either simplex or duplex. The scanning station associated with scanning the simplex side of the document projects line images of the scanned document along an optical path onto a light sensitive image medium. In a first embodiment, the projection device is a linear gradient index lens array and the light sensitive member is a linear sensor array. The scanning station associated with scanning the second, duplex, side of the document projects the duplex side line images, via a second gradient index lens array, along an optical path which is generally optically aligned with, and includes, the first optical path. Thus, the duplex line images are projected through a first gradient index lens array whose output is optically coupled into and projected by the lens array associated with the simplex scanning. Control devices are provided to enable a simplex or duplex mode of operation. Several embodiments of the invention are provided to demonstrate feasibility with document feeder inputs at different locations.

摘要： A printing system operating in a charged area development environmental utilizes a high resolution image print bar in cooperation with a low resolution image discharge bar to expose a charged surface of a photoreceptor with a minimum of stress being applied to the high resolution bar. The high resolution bar is addressed from an image data source so as to expose areas of the photoreceptor which correspond to informational areas of the image being printed. The low resolution bar is addressed from the same data source so as to discharge the photoreceptor surface in non-informational areas such as background areas and interimage areas. In a preferred embodiment, both the high and the low resolution bars are LED arrays located in a common exposure station.

摘要： A compact machine architecture is realized by combining the functions of copy sheet feeding and stacking into one integral apparatus. The apparatus is initially completely filled with copy sheets to be moved into the transfer/fusing area of a copier/duplicator machine. A vertically translatable stacker tray is positioned above the copy sheet input and is moved downward in vertical synchronism with copy sheets being fed from the input stack. A paper feed roller, attached to the bottom of the tray, continually feeds the top sheet from the input supply. As the input sheet stack is consumed, the output (feed) copies are deposited onto the stacker tray. As operation continues the supply stack is depleted while the finished stack increases, but the overall volume occupied by the copy sheets remains the same. Since there is no "empty" volume in the apparatus, the size and cost of the unit is greatly reduced.

摘要： A printer having a color copy capability is enabled by scanning an original document having at least two discrete colored areas onto a color-filtered photosensor array simultaneously with formation of an electrostatic image of the original on a photoconductor member. The array generates output signals corresponding to detected color areas of the original document. These signals are sent to the printer software which determines the detected color image coordinates of each portion of the output copy. Output copies are then made, using multiple imaging erase and development passes.
