Abstract: An integrated imaging bar assembly. The single-assembly scan and imaging head comprises two sub-assemblies, one having a raster input bar and the other a raster output bar including their respective lens array systems. Each sub-assembly has a heat sink attached to its respective bar and the sub-assemblies are conjoined at a heat shield that separates them from each other while forming a single integrated imaging bar assembly.
Abstract: A printing apparatus may include a heating element with at least one of a contact fuser, a radiant fuser, a substrate preheater, an image bearing member heater, and a transfuser, the heating element including a lattice of filaments wherein the filaments are separated from each other by a spacing and the spacing is such that an energy input into the heating element is radiantly output in a specific frequency band. A method of using a printing apparatus may include providing a heating element that is part of the printing device and that includes a lattice of filaments wherein the filaments are separated from each other by a spacing and the spacing is such that an energy input into the lattice is radiantly output in a specific frequency band, and performing at least one printing operation.
Abstract: A carrier bead pickoff device is provided for removing ferromagnetic carrier beads from a developed image-carrying surface of a moving photoreceptor in an electrostatographic image reproduction machine.
Abstract: A method and apparatus for printing a project of documents containing variable data. Print requests are received for documents and fixed and variable data required to fulfill the requests is obtained. A record is manipulated for each set of variable data in a project and correlated to the variable data. The fixed data and the variable data are combined to compose the documents and the documents in the project are printed by combining the fixed data and the appropriate variable data. An identifier can be printed on each document to permit verification that a document corresponding to each record was printed.

Abstract: There is provided a surface emitting semiconductor laser satisfying a requirement of making a transverse mode stable and having characteristics of high output power, low resistance, high efficiency, and high speed response and a method for manufacturing the surface emitting semiconductor laser. Five holes are formed on the top surface of an upper multilayer reflection film formed in the shape of a post by the use of a focused ion beam (FIB) processing unit. One hole is formed on the surface of an upper multilayer reflection film corresponding to the center position of a square current injection region which is about 8 ?m square and the remaining four holes are formed at the corners of the square current injection region, for example, at the positions about 2 ?m square away from the one hole to produce four light emitting spots.

Abstract: A parallel, non-iterative, memory efficient method of determining image skew. A document skew angle is determined from a fast scan second order moment data set and a slow scan second order moment data set. A slow scan second order moment data set can be generated by receiving a current scanline of image data, updating columns sums for a set of rotation angles using scanlines within a buffer comprising a band having a predetermined number B of scanlines, and updating the buffer with the current scanline.
