Abstract: In a xerographic printing apparatus, feedback on surface charge at a plurality of locations across a length of a photoreceptor may be desirable to assess charge uniformity, for example, to ensure color consistency across multiple marking engines in tightly integrated parallel printing architectures. A cross process charge uniformity scanner may include at least one micro-electro-mechanical based electrostatic voltmeter device for measuring surface charge at a plurality of locations along the length of the photoreceptor. The charge uniformity scanner may allow the xerographic printing apparatus to initiate charge device cleaning and/or control the intensity of the charge applied to the surface of the photoreceptor. Exemplary embodiments may include an electrostatic voltmeter moveably mounted along the length of the photoreceptor in the fast scanning direction, or may include a plurality of electrostatic voltmeters disposed at spaced apart locations along the length of the photoreceptor.

Abstract: A planning system for the planning and management of multiple projects includes an input (122) for entering project information and task information associated with each project. The project information identifies each project as being of a mandatory, nonmandatory, or ad hoc type that arises intermittently and is subject to change. The task information describes each task to be performed by users of the system and an estimated duration of each task. Also included are a work hour calculator (124), an allocation engine (128), a schedule preparation engine (130), a time tracking system (132), and a time imbalance calculator (134). An allocation modification engine (136) reestimates the time required for completing each project based on the actual time spent and current status for each project and reallocates time to eliminate any time imbalance detected by the time imbalance calculator.

Abstract: A fuser system and method for a xerographic device having improved self-stripping capabilities for a wide latitude of substrate media. The fuser system includes a fuser member and a pressure member in which the pressure member is made to exert a predetermined pressure upon the fuser member. In applying this pressure load, a nip is formed having a nip width between the fuser member and the pressure member. A predetermined creep exists during normal fusing of a substrate. A load adjustment device is provided to momentarily increase the exerted pressure as a leading edge or other portion of the substrate passes through, and/or in the vicinity of, the nip, thereby increasing the creep magnitude momentarily and improving self-stripping capabilities.

Abstract: A scanner is connected to a host computer. A scanner control routine is installed onto the host computer and used to generate and forward control signals to the scanner or multi-function device. Using the scanner control system, manager or routine, one or more scanned image destinations are defined and one or more scanning parameters are defined that are particularly appropriate for each such scanned image destination. Each scanned image destination is associated with one of a number of pre-named scanner destinations that can be selected using the scanner. These pre-named destinations usually have generic or otherwise meaningless names that are not associated with any particular destination or location. The user uses the control panel of the scanner or multi-function device to select one of the pre-named destinations. The scanner or multi-function device forwards this selected destination to the host computer.

Abstract: The presently described embodiments provide electric paper, in one form, that is bisymmetrical, both sides of the paper have the same thicknesses of mylar layers and the same thicknesses and patterns of ITO islands. In another form, a disordered layer of conductive particles, non-conductive particles and display elements has the same percolation threshold throughout, and thus is bisymmetrical. In either form, in a system for printing all asymmetries in the printing process are transferred to the printhead, just like in conventional ink printers and paper. As a result, both sides of the electric paper are equally capable of being printed on, just like conventional paper, and the electric paper has the same flexural properties when flexed in a concave or convex manner, just like conventional paper. This construction has the additional practical advantage that there is no longer any need to ensure the electric paper is oriented “right side up” before printing on it.

Abstract: A method of categorizing objects in which there can be multiple categories of objects and each object can belong to more than one category is described. The method defines a set of categories in which at least one category is dependent on another category and then organizes the categories in a hierarchy that embodies any dependencies among them. Each object is assigned to one or more categories in the set. A set of labels corresponding to all combinations of any number of the categories is defined, wherein if an object is relevant to several categories, the object must be assigned the label corresponding to the subset of all relevant categories. Once the new labels are defined, the multi-category, multi-label problem has been reduced to a multi-category, single-label problem, and the categorization task is reduced down to choosing the single best label set for an object.
