Abstract: A developer unit is arranged with a replenish port for adding developer compound to the developer pan. The replenish port is arranged so that developer compound added to the replenish port falls through the port to an inclined ramp at one end of the developer pan. Further, the inclined ramp's angle of incline is arranged to exceed the developer compound's angle of repose. As a result, the added developer compound flows down the ramp and towards the agitator. The agitator, in turn, propels the developer compound towards the donor roll.

Abstract: A method and apparatus for compressing a mixed raster content image that represents a color or gray scale a document is disclosed. The pixel map is decomposed into a three-plane representation—a reduced-resolution “upper” plane, a reduced-resolution “lower” plane, and a high-resolution binary selector plane. An iterative smoothing technique is then used to pre-process the upper and lower planes using the information contained in the selector plane, thereby reducing the amount of data that will be subjected to further processing.

Abstract: A print processing apparatus realizes high speed processing of input data which includes various types of drawing objects such as images, graphics and characters. In the apparatus, input data generated by an input data generating unit is converted into intermediate data in an intermediate data generating element. An intermediate data order controlling element rearranges intermediate data pieces based on overlap therebetween and classifies them into groups, in each of which the data pieces can be processed in parallel. A group ID indicating a group for parallel processing, a hardware configuration ID and so on are assigned to the intermediate data piece. A rasterizing unit receives configuration data from a configuration data administering element, if necessary, in accordance with the hardware configuration ID assigned to the intermediate data piece, and rewrites a function of a reconfigurable rasterizing element under the control of the reconfiguration controlling element.

Abstract: An apparatus and method of making very small curvature modifications of the reflective surface of a mirror in a printer raster scanning system for bow correction of the scanning beam by gripping edges of the mirror to bend it with a gripping system and applying a very small movement thereto by gross rotation of screw shaft of a differential screw system operatively connected to that gripping system. The screw shaft has two separate fine screw thread patterns of slightly different screw pitches causing gross rotation of the screw shaft to only move the mirror gripping system and its engaged portion of the mirror by micro-meter amounts by automatically subtracting the two slightly different screw pitches from one another, thus providing very small, easily controlled, deformation of the mirror plane for bow correction by non-critical gross rotation of the screw shaft.

Abstract: An image processing apparatus comprises a tandem print engine configuration for forming two-sided prints. The print engines include a master print engine and a slave print engine downstream from the master print engine. The image processing apparatus matches the periods of revolution of the photoreceptors of the master and slave print engines during print runs, by simultaneously adjusting both the velocity of the slave photoreceptor and color imagers of the slave print engine. The velocity controllers for the slave photoreceptor and imagers can have the same dynamic response and can be simultaneously actuated, to minimize incremental registration errors in the slave print engine. In addition, the controllers can be operated at an adjustment level that is achievable by both controllers.

Abstract: A single rotating polygon mirror with adjacent facets having different tilt angles reflects and splits the scanning beam to multiple photoreceptors in a raster output scanning (ROS) system. The mirror can have two or four alternating facets with different tilt angles. Two different light beams form two different light sources can be reflected and split from the polygon mirror contemporaneously to multiple photoreceptors. The split beams from the polygon mirror facets can share a common f-theta scan lens.

Abstract: A light emitting diode based exposure station (and electrophotographic marking machines that use such exposure stations) that requires only a small amount of photoreceptor waterfront (space). The small waterfront requirement is achieved using a gradient index lens array that transmits focused light onto the photoreceptor with a total conjugate that is sufficient to permit the widest part of the light emitting diode based exposure station to be displaced sufficiently far from the photoreceptor that other printing machine devices can be disposed between the widest part of the exposure station and the photoreceptor. The increased total conjugate is achieved using a gradient index lens array having longer rods and/or wider rods.

Abstract: A method detects if an image is compressed. The method determines a block grid within the image and establishes blocks from the determined grid. The method then computes differences between samples inside the established blocks and differences between samples across the established blocks. The method determines that the image is compressed based on characteristics derived from statistics of the computed differences.

Abstract: An acoustic ink print head includes an array of individual emitters. Each of the emitters have a corresponding transducer with a lower electrode, a separate layer of a piezo-electric material located on the lower electrode, and a separate upper electrode provided on the upper surface of the piezo-electric layer. The upper and lower electrodes are connected to a source of conventionally modulated RF power. A dielectric layer is deposited on top of this structure and lenses are etched into the top of the dielectric layer. The lenses focus energy generated by the transducer to a region of the upper surface of a body of liquid located above the transducer. The lenses concentrate sound waves from the transducers thereby disturbing the surface and causing droplets to be emitted. The print head is formed as an array of individual emitters. The upper electrodes of the individual emitter array have varying surface areas dependent upon their location within a row of electrodes and their output efficiencies.

Abstract: Formatted code data are sequentially input to an input terminal A. A receiving section 11 passes a header portion etc. to a control section 16, and causes selection codes (output to CDS) and text color codes (output to CDC) to be stored sequentially in a storage section 15. When pattern codes are output to CDI and input to an expansion section 12b, the control section 16 reads out the selection codes and the text color codes from the storage section 15 with such timing that pixels at the same position are output simultaneously from image conversion sections 13a-13c, and inputs those codes to expansion sections 12a and 12c. The respective compressed codes are expanded by the expansion sections 12a-12c, converted by the image conversion sections if necessary, and then input to a composing section 14. At this time point, respective data corresponding to pixels are timed with each other, which allows a correct composing process to be executed in the composing section 14.

Abstract: An imaging system for effecting electrostatic printing of an image, wherein the imaging system includes at least one contact electrostatic printing engine operable in a novel fashion upon a copy substrate, for imaging and development of a latent image representative of the image, and subsequent transfer of the developed image to the copy substrate. The developed image is created by separating and selectively transferring portions of a high solids content secondary toner cake layer in correspondence with the image and non-image regions of the latent image. A toner cake layer delivery apparatus draws from a supply of high solids content liquid developing material to form a primary toner cake layer on a movable donor member. The primary toner cake layer is subject to uniform charging to a first polarity followed by an induced charge of a second, opposing polarity to a selectable depth.
