Abstract: Embodiments described herein are directed to validating an aggregate document. An instance signature can be generated for a first instance of a data page retrieved for inclusion in the aggregate document and can be compared to a baseline signature associated with a second instance of the data page. A similarity value can be calculated in response to the comparison. The similarity value indicates a degree of similarity between the first instance and the second instance of the data page. Based on the similarity value it can be determined whether to delete or bypass the data page in the aggregate document.

Abstract: A system for maintaining depth of focus in an ink jet printer between a series of print heads and corrugated media includes a vacuum transport in combination with a heating element positioned upstream of the series of print heads in order to help the vacuum transport acquire the corrugated media and seal edges of the corrugated media against a platen.

Abstract: A continuous web inversion system for use in a continuous web imaging device includes a first turn bar positioned to receive a substantially continuous web moving in a first direction with a first surface facing in a printing direction and to flip the web and direct it in a second direction perpendicular to the first direction. A second turn bar is positioned to receive the continuous web from the first turn bar to flip the web and direct it in a third direction opposite the first direction. A third turn bar is positioned to receive the continuous web from the second turn bar to flip the web and direct it in the first direction with a second surface of the web facing in the printing direction. The second and the third turn bars are coupled together and supported for translation along an axis perpendicular to the first direction. A sensor is configured to generate a signal indicative of a lateral position of the continuous web exiting the third turn bar.

Abstract: A circuit board including a plurality of components; a plurality of light sources aligned along at least one axis; and a controller configured to activate the light sources to identify at least one of the components. The components on the circuit board can be identified by the light sources in response to a variety of conditions.

Abstract: An improved architecture for use in a tightly integrated serial or parallel printer includes an inverter module that comprises a straight pass-through media path, as well as, an invert path. This auxiliary ‘pass-through’ media path of the inverter allows a sheet to enter the inverter ‘backwards’ through the traditional duplex exit path and continue straight out the inverter into the media path of a downstream engine to receive an image thereon.

Abstract: A method enables an inkjet printing system to attenuate image noise in an image of a test strip obtained as print media bearing the test strip travels over a roller in the printing system.

Abstract: A printer is configured with a controller that transforms operation of the printer to increase throughput. The printer includes an image receiving member, a printhead configured to eject ink drops onto the image receiving member to form an ink image, a transfix roller configured to move towards and away from the image receiving member to form a transfixing nip with the image receiving member selectively, a release agent applicator configured to engage the image receiving member selectively to apply release agent to the rotatable imaging member, and a controller configured to generate firing signals that operate the printhead from image data and to transform operation of the printer from a first printing process sequence to a second printing process sequence in response to a coverage parameter for image data to be printed being less than a predetermined threshold.

Abstract: A computer-implemented method for performing color registration on template media having template markings thereon.

Abstract: A method and system have a media path having moving devices that move a media sheet in a processing direction. At least two elongated sensors within the media path are positioned diagonally relative to the processing direction. The media sheet has two lateral sides, a leading edge, and a trailing edge. A registration controller is operatively connected to the media path and to the elongated sensors. Each of the elongated sensors simultaneously identifies: a location of one of the lateral sides of the media sheet, such that a combination of the elongated sensors simultaneously outputs at least two lateral measures of locations of the lateral sides of the media sheet; and at least one measure leading edge or at least one measure of the trailing edge of the media sheet.

Abstract: A document imaging system includes a document transport system that transports an original document through an imaging zone in optical communication with an image recording device. A document guide directs the original document, including a leading edge at a first angle, toward the imaging zone, while a document biasing device urges a trailing edge of the original document at a second angle toward the imaging zone.
