  • Patent number: 7331655
    Abstract: Plural film layers are disposed on a substrate. Each film layer has regions devoid of film material, thus forming film layer cavity openings. Each film layer has its cavities arranged to provide fluid coupling with its adjacent film layer or layers. The film layer cavities form a traverse channel coupling the top and bottom film layers and also one or more lateral channels coupling cavity openings in the top film layer. The film layer traverse channel couples with a substrate channel that extends from the substrate top surface to one or more of its other surfaces. A device such as a fluid dispenser, fluid ejector, sensor or bioprocessing device is disposed on the top film layer and fluidly coupled to the plural film layers traverse and lateral channels. The traverse channel and the one or more lateral channels are arranged to transport or flow one or more fluids.

  • Patent number: 7315724
    Abstract: An original comprises a first page and a second page as disposed face-down on the platen surface of an image-processing device. The platen is scanned to form a platen image. The positions of two diagonally-opposite corners of the original are determined based on a fixed platen reference point. An original image is formed by cropping the platen image based on the positions of the two original corners. The size and position of either one selected page or both pages are determined based on the two original corner positions. When the image of only one selected page is desired, the image of the selected page is formed by cropping the original image based on the size and position of the selected page. When the images of both pages are desired, the images of both pages are formed by cropping the original image based on the sizes and positions of both pages.

  • Patent number: 7280793
    Abstract: A fuser assembly includes a pressure member motion speed reduction device which slows the pressure member speed when the printed paper lead edge exits the nip. The temporarily slower pressure member speed stretches or retards the surface of the fusing member elastomer enough to assist in peeling the lead edge from the fusing member thereby allowing the rest of the paper to peel off. In one embodiment, the paper stripping or peeling process is assisted by means of one or more air knives, one or more stripping fingers, or any combination of these items.

  • Patent number: 7158858
    Abstract: A media handling system comprises a configuration of N linked modules. Each module has an order based on the module's linkage in the configuration. Thus, a first module of order 1 links to a second module of order 2, the second module links to a third module of order 3, etc., and an (N?1)th module of order (N?1) links to an Nth module of order N. A feeder module feeds a sheet of media to downstream modules. Each downstream module sends a reporting message to an included controller. The reporting message includes the time the module processed the sheet and the module's reported type. For each reporting module, the controller determines the module's order and type based on the reported time and reported type in the module's reporting message. The controller validates the configuration by determining when the order and the type for the reporting modules match a predetermined pattern.

  • Patent number: 7116930
    Abstract: Dispenser conduit partitions are used to improve the discharge flow of toner particles from a toner dispenser bottle in a host image forming device. A dispenser conduit partition assembly is inserted into the funnel-like dispenser conduit of the toner dispenser bottle. The conduit partition assembly is arranged with multiple partition members. The multiple partition members act to partition the single symmetric dispenser conduit into a corresponding multiplicity of asymmetric dispenser component conduits. As a result, the toner particles are dispensed by the multiple dispenser component conduits to thereby form a corresponding multiplicity of asymmetric toner particle discharge flows, thus reducing toner bridging.

  • Patent number: 7085012
    Abstract: An image forming device includes a backing and is arranged for a media to be positioned against the backing. The backing includes an embedded backing pattern. The media is skewed with respect to the scanning, thus defining a media skew. The media and the backing are scanned to form a pixel pattern. For each pixel, an included pattern recognition algorithm determines when the pixel represents the backing. When the pixel represents the backing, it is replaced with a replacement backing symbol, otherwise it is replaced with a replacement media symbol. The pixel determining and symbol replacing process is continued for remaining pattern pixels to form a replacement symbol pattern comprised of the replacement backing symbols and the replacement media symbols. The media is then processed based on the replacement symbol pattern, the processing including detecting the media skew, registering the media, or both.

  • Patent number: 6983088
    Abstract: A thermal actuator comprises a plurality of substantially straight and parallel beams arranged to form a beam array. The midpoint of each beam is attached or coupled to an orthogonal coupling beam. Each array beam has a beam heating parameter with a corresponding beam heating parameter value. The beam heating parameter values vary across the beam array based on a predetermined pattern. As the beams are heated by an included heating means, the distribution of beam temperatures in the beam array becomes asymmetric, thus causing the beam array to buckle. The buckling of the beams in the beam array, in turn, causes the attached coupling beam to move in a predetermined direction. The coupling beam motion, in turn, operates an included optical waveguide switch. The beams in the beam array are heated by any of Joule heating, eddy current heating, conduction heating, convection heating and radiation heating.

  • Patent number: 6963717
    Abstract: A fuser stripper baffle exit minimizes differential gloss marks due to paper contacting the fuser exit baffle. Portions of paper that touch the baffle cool differently than portions that don't, resulting in differential gloss in the paper path or spanwise direction. The exit baffle contains a series of axial-direction steps or plateaus in its upper surface, such that the highest step is nearest the fuser roll, while the lowest plateau is furthest from the roll. This reduces the surface area of the fuser stripper baffle exit that contacts the surface of the paper sheet as the paper sheet is stripped from the fuser roll. The paper thus touches the exit baffle for the minimum amount of time, thus minimizing the heat transfer to the baffle. This minimizes differential cooling effects which, in turn, minimizes differential gloss.

  • Patent number: 6711363
    Abstract: A printing machine comprises a charging device that forms a variable operating voltage. A charging device pre-fault status condition is determined by sampling the charging device operating voltage, forming a slope value based on a charging device operating voltage rate of change per unit time, and determining when the slope value falls in a charging device pre-fault status range of values. When the pre-fault status determination is made, a message is formed based on a current print count value. This message is then sent to a user or operator. When the print count value falls in a charging device replacement range of values, a replacement message is sent to inform that the charging device needs to be replaced. Otherwise, when the print count value does not fall in this range of values, a cleaning message is sent to inform that the charging device needs to be cleaned.
