  • Publication number: 20110285073
    Abstract: A 3-way letterbox media diverter directs and controls media in 2 forward directions and 1 reverse direction within a printer's paper path. The letterbox design enables actuation of the diverter from a first position to a second position just as the trail edge of a sheet passes a post fuser nip. Once the diverter reaches the second position, an invert nip now controlling the sheet is reversed to thereby invert the sheet. Thus, inversion of the sheet is accomplished in a small space envelope, time to reverse direction is reduced, process speed can be reduced and additional paper guides are eliminated.

  • Publication number: 20110288821
    Abstract: Systems and methods of determining a predicted usable life of components, such as a photoreceptor, associated with an imaging device. The systems and methods include a power source configured to increase an electric field across the photoreceptor. A sensor or array is configured to detect charge deficient spots (CDS) in a charge transport layer (CTL) of the photoreceptor as a result of increasing the electric field. The systems and methods are configured to determine the predicted useable life of the photoreceptor based on the detected CDS. The systems and methods are further configured to output a report of the estimation. The estimation is conducted at fixed or variable intervals throughout the life of the photoreceptor and/or imaging device.

  • Publication number: 20110286753
    Abstract: Systems and methods of diagnosing a photoreceptor associated with an imaging device. The photoreceptor is configured to enter into a diagnostic cycle to complete a set number of cycles. A sensor or array is configured to a scan a component associated with the imaging device during each of the set of cycles to establish defect data. The defect data is analyzed to filter one or more charge deficient spots (CDS) from background noise in the defect data. The systems and methods determine whether the photoreceptor needs replacement based on the determined one or more CDS. The systems and methods are further configured to output a report of the determination. The determination is conducted at fixed or variable intervals throughout the life of the photoreceptor and/or imaging device.

  • Publication number: 20110286014
    Abstract: What is disclosed is a novel system and method for determining a printer metric in terms of image quality (IQ) over a large complex set of conditions based upon measurements taken over a small simple set of conditions while compensating for printer drift. The present system and method effectively utilizes a predictive model that predicts noise measurements of multi-separations from those of single-separation colors and/or a subset of the multi-separations. Because a model is used to comprehend the metric over the entire gamut, the number of patches is reduced. This reduction enables the method to be used within a machine to dynamically characterize the device's image quality metric. Various embodiments have been disclosed.

  • Publication number: 20110289395
    Abstract: The invention converts a document originating in a page-image format into a form suitable for an arbitrarily sized display, by reformatting or “re-flowing” of the document to fit an arbitrarily sized display device. A two-stage system analyzes, or “deconstructs,” page image layout. The deconstruction includes both physical (geometric) and logical (functional) segmentation of page images. The segment that image elements may include blocks, lines, and/or words of text, and other segmented image elements. The segment that image elements are synthesized and converted into an intermediate structure. The intermediate data structure is then distilled or converted or redisplayed into any number of standard print formats.

  • Publication number: 20110288852
    Abstract: A system and a method for phrase-based translation are disclosed. The method includes receiving source language text to be translated into target language text. One or more dynamic bi-phrases are generated, based on the source text and the application of one or more rules, which may be based on user descriptions. A dynamic feature value is associated with each of the dynamic bi-phrases. For a sentence of the source text, static bi-phrases are retrieved from a bi-phrase table, each of the static bi-phrases being associated with one or more values of static features. Any of the dynamic bi-phrases which each cover at least one word of the source text are also retrieved, which together form a set of active bi-phrases. Translation hypotheses are generated using active bi-phrases from the set and scored with a translation scoring model which takes into account the static and dynamic feature values of the bi-phrases used in the respective hypothesis. A translation, based on the hypothesis scores, is then output.

  • Publication number: 20110286015
    Abstract: What is disclosed is a novel system and method for converting a set of L*a*b* values to CMYK color space in which all CMYK formulations that produce each L*a*b* value are found and enumerated. The CMYK formulations are found through a search algorithm starting with the lightest L*a*b* values then visiting neighboring L*a*b* values until the entire L*a*b* color set has been processed. The CMYK space is tessellated into a set of pentahedrons, and for each L*a*b* value, an enclosing pentahedron is found and the CMYK values corresponding to where the locus of this point penetrates each surface is recorded. Adjacent pentahedrons are then visited and this process continues until the gamut boundary is reached. The result is a piecewise linear representation of the CMYK locus containing all values that will give the target L*a*b* value. The present method provides a flexible and powerful approach for solving color management problems.
