Abstract: A non-gated print media crossover for a printing system includes crossover pathways which intersect at a crossover junction. A control system controls arrival of sheets of print media at the crossover junction whereby a sheet conveyed on the first crossover pathway traverses the junction in an intersheet gap between sheets traversing the junction on the second crossover pathway. The printing system includes print media processing units, such as marking engines, paper sources, and output destinations, which are connected by a conveyor system incorporating the crossover.
Abstract: A class is to be characterized of a probabilistic classifier or clustering system that includes probabilistic model parameters. For each of a plurality of candidate words or word combinations, divergence of the class from other classes is computed based on one or more probabilistic model parameters profiling the candidate word or word combination. One or more words or word combinations are selected for characterizing the class as those candidate words or word combinations for which the class has substantial computed divergence from the other classes.
Abstract: An imaging member including a substrate; thereover a charge generating layer; thereover a first charge transport layer comprising a small molecule charge transport material and a polymeric component selected from the group consisting of polyarylamine polyester, polyacylamine, and mixtures and combinations thereof; and a second charge transport layer disposed over the first charge transport layer, the second charge transport layer comprising a small molecule charge transport material and a binder, wherein the second charge transport layer is free of polyarylamine polyester and polyacylamine.

Abstract: The presently disclosed embodiments are directed to release fluids or agents that are useful in release coating in toner-based technologies. More particularly, the embodiments pertain to the addition of metal chelating agents to release fluids to prevent byproduct reactions from the fusing process that would otherwise decrease fuser member life and image quality.
Abstract: A method of indexing images contained in scanned documents, wherein said scanned documents are stored in a repository, includes: for each document to be stored in the repository, dividing the document into a plurality of sections; scanning the plurality of sections; segmenting each scanned segment according to a predetermined coding model into image segment and non-image segments; associating each of the image segments with the document; and generating an index correlating the image segments with the document. The method may further include, at the time of image recall, displaying the index of image segments in a user interface; and responsive to selection of an image segment from the index, displaying the document information associated with the image segment in the user interface.
Abstract: Disclosed is a compound of the formula and dimers thereof, wherein R, R?, X, (Y)m, and (Z)n are as defined herein. The compounds are useful as colorants, particularly in applications such as phase change inks.

Abstract: An image-forming medium and methods for forming and imaging the medium are provided. The disclosed medium can be strongly colored under room illumination (or deliberate UV) and can be selectively discolored at an appropriate light wavelength to form an image. In one embodiment, the image-forming medium can include a substrate (e.g., a sheet of paper), a photochromic material incorporated with the substrate, and a photo-absorbing material incorporated with the photochromic material. Exemplary methods for using the image-forming medium to make a transient image can include first forming the image-forming medium by applying a coating solution containing photochromic material to the substrate or paper. The image-forming medium can have a medium color and can then be selectively exposed to a radiation through a mask to convert the photochromic material from a colored form to a colorless form and thus to form an image having a color contrast with its background.
