Abstract: This is an electrophotographic marking system that effectively cleans residual toner and toner additives from the surface of a photoreceptor of a marking system, by improved toner and toner agent removal expedients . This cleaning process reduces ghosting problems that had been encountered in final copies produced by electrophotographic systems such as in copier, printers and duplicators. This cleaning is accomplished by expedients such as increasing a cleaning brush bias, and by increasing the surface area of cleaning brushes used in the system. In addition, the development process is desensitized to the development of ghosting. This desensitizing is accomplished by expedients such as increasing the gap between the development roll and the photoreceptor and by reducing the AC development electrical bias.

Abstract: This is a cleaning roll for a xerographic cleaning station. The roll comprises a compliant foam layer covered with a fabric overcoating. The cleaning station also contains a detoning roll which contacts the cleaning roll to attract residual toner for disposal out of the station. There is an electrical connection in the station to a biasing structure which will bias both the fabric overcoating and the detoning roll. The conductive fabric has an average roughness (RA) not exceeding about 8 ?m to 10 ?m and the fabric comprises yarns of similar size to provide thereby a smooth and uniform surface texture.

The exemplary method includes receiving a dataset of text sequences, automatically identifying a set of patterns in the text sequences, and filtering the patterns to generate a set of features. The filtering includes at least one of filtering out redundant patterns and filtering out irrelevant patterns. The method further includes outputting at least some of the features in the set of features, optionally after fusing features which are determined not to affect the classifiers accuracy if they are merged.

Abstract: A first movement control section sequentially moves a first image to multiple first positions. A first comparison section compares the moved first image with a second image. A target first position selection section selects a target first position based on the result of said comparison. After the target first position is selected, the second movement control section sequentially moves the first image to multiple second positions located in the periphery of the target first position. The second comparison section compares the moved first image with the second image. A target second position selection section selects a target second position based on the result of said comparison. A second position alignment execution section performs geometric transformation based on the difference between the position of the first image and the target second position and aligns the positions of the first and second images.

Abstract: Provided is a method for enabling accurate and consistent imaging of selected colors within a document for various printing device configurations utilizing an automated spot color editor. The method includes determining appropriate target values for a selected color within a print job. The automated spot color editor modifies or adjusts the selected color by selecting a quality level, in the form of a color difference metric, and a maximum number of iterations, which is the maximum number of times the automated spot color editor is operated to calculate a CMYK color formula. Sample patch(es) are printed and analyzed for the selected target value and a CMYK color formula based on the color composition of the sample patch is calculated. The CMYK color formula is inserted into a spot color editing table. Through a graphical user interface, an operator may review the color formula for acceptance.

Abstract: When a TAB assembly is used in the transfer station of an electrostatic marking system, the blade used in the TABs becomes deformed or improperly aligned due to lateral movement of the clamp, held by rivets, which is used to maintain proper blade alignment. Provided herein is a simple, yet effective, way to secure this clamp with embedded burrs so that the useful life of the TAB is more than doubled over prior art TABs.

Abstract: A method of forming an enclosed fluid path in a print head includes providing a die member and a truncated nozzle plate spaced from the upper surface of the die member. The die and nozzle plate are formed on a print head substrate having an aperture formed therein. A sacrificial material is seated over the aperture of the print head substrate and joins a terminal end of the truncated nozzle plate. The sacrificial material is encapsulated from the terminal end of the nozzle plate to a surface of the print head substrate. Removal of the sacrificial material defines the fluid path from the aperture of the print head substrate to the nozzle plate.

Abstract: A Hybrid Scavengeless Development electrophotographic printing system is provided wherein the electrode wires contain carbon nanotube yarn. The use of carbon nanotube yarn alleviates the problem of fundamental strobing image defects, because the electrodes made from the carbon nanotube yarn can be put at a higher tension to density set point, and thereby achieve fundamental resonance frequencies larger than that obtainable from steel. Additionally the yarn's strength is sufficient to withstand the typical forces it is subjected to in a Hybrid Scavengeless Development environment.

Abstract: In a droplet ejecting system, after an ink droplet is ejected a reverberation pressure change is amplified to obtain an appropriate amount of reverberation pressure change, and the ink droplet is reliably separated from a meniscus when ejecting the ink droplet. To this end, voltage including an ejecting pulse for ejecting the ink droplet is applied to a piezoactuator to generate a pressure change in a pressure chamber, and voltage including a reverberation amplifying pulse is applied to the piezoactuator to amplify the pressure change in the pressure chamber in the next cycle subsequent to the cycle of the pressure change generated by the ejecting pulse.
