Abstract: A cleaner assembly for an electrophotographic image forming device according to one example embodiment includes a cleaner blade having a pair of longitudinal ends and a cleaning edge that extends between the pair of longitudinal ends for contacting a surface of a photoconductive drum to remove toner from the surface of the photoconductive drum. An end seal is positioned at one of the pair of longitudinal ends of the cleaner blade. The end seal includes a front side positioned to contact the surface of the photoconductive drum and a rear side opposite the front side. A tab extends from the end seal across the cleaning edge of the cleaner blade for preventing a longitudinal end section of the cleaning edge of the cleaner blade from contacting the surface of the photoconductive drum. The tab does not obstruct the front side of the end seal.

Abstract: A page-wide inkjet printer for determining a drying time of a print swath of ink deposited on a sheet of media by a fixed printhead spanning a width of a printing zone in a subscan direction. The printer has a controller communicatively coupled to each of the printhead and a moveable gloss sensor or a scan bar for processing a respective output response for the determining the drying time of the print swath.

Abstract: A cleaner assembly for an electrophotographic image forming device according to one example embodiment includes a cleaner blade having a pair of longitudinal ends and a cleaning edge that extends between the pair of longitudinal ends for contacting a surface to remove toner from the surface. A strip is attached to the cleaner blade at one of the pair of longitudinal ends of the cleaner blade. The strip is wrapped over the cleaning edge of the cleaner blade for preventing a longitudinal end section of the cleaning edge of the cleaner blade from contacting the surface.

Abstract: An ink composition for used in an inkjet printer is provided. The ink composition includes a carrier medium, a colorant, and a silicon doping agent. The silicon doping agent may include silicic acid, silicon dioxide, or silicates. This silicon-doped ink reduces and prevents the etching of the silicon based components of the printhead. Silicon-doped inks protect the printhead from damage, thus improving printhead reliability and increasing printhead service life.

Abstract: An inkjet printer for determining drying time of a print swath of ink deposited on a sheet of media by use of a dual function alignment sensor operable in a first mode to provide an output response corresponding to an amount of bi-directional misalignment of dot placement by the plurality of nozzles sensed from scanning a printed alignment test pattern, and in a second mode to provide an output response corresponding to an amount of specular reflection received from the print swath of the printed image with the output response in the second mode being used to determine if the printed image is sufficiently dry to be moved.

Abstract: A method for determining drying time of a print swath of ink deposited on a media sheet by an inkjet printer. The method comprises performing a predetermined number of sequential scans of a print swath with a gloss sensor; processing output responses thereof to determine and store gloss values; calculating percent differences between the gloss values; and, based on the calculated percent differences, selecting one of a long dry time and a short dry time before moving the media sheet.

Abstract: A method for determining drying time of a print swath of ink deposited on a media sheet by an inkjet printer having a controller communicatively coupled to each of a printhead and a gloss sensor. The method comprises forming the print swath on the media sheet; scanning the print swath with the gloss sensor; processing an output response thereof to determine and store a gloss value; starting a predetermined scan interval and waiting scan interval to elapse; performing a next scan of the print swath with the gloss sensor; processing a next gloss sensor output response to determine and store a next gloss value; and, if the gloss value and next gloss value are within a predetermined range moving the media sheet for further processing including duplexing.

Abstract: The disclosure relates to circuits and methods for the manufacture of circuits, such as those which avoid the formation of undesirable short circuit paths. One such method maintains a layout area of a fluid composition receiving layer within a layout area of a dielectric layer. Another such method relates to the application of fluid composition receiving layers, conductive layers, and dielectric layers, such as in the provision of printed circuits.
