摘要： A stripper blade assembly for an ink jet offset printer has a thin blade fixedly mounted on a top surface of a blade holder. The blade holder includes at a trailing edge flexible eyelet portions that extend downwards to snap over protuberances on mechanical connectors overmolded onto a rotatable shaft in order to secure the blade holder to the shaft. The thin blade engages the surface of an offset drum of the ink jet offset printer along the width of the drum at an appropriate point in the print process to strip the leading edge of a print medium from the offset drum surface, minimizing damage to the offset drum surface and to the printed image on the print medium while also minimizing the risk of a jam.

摘要： A media guiding apparatus and related method for reliably directing a media sheet from a media tray to a transport nip are provided. In one embodiment the media guiding apparatus includes at least one guide member that extends from a first guide surface adjacent to the transport nip to the sheet separator in the media tray. The guide member cooperates with a second guide surface to create a substantially uninterrupted media path between the sheet separator and the transport nip. The guide member is also extendible as the sheet separator moves relative to the first and second guide surfaces within the media tray. In another embodiment, the media guiding apparatus comprises a fan that creates a positive air pressure that urges the sheet against a guide surface as the sheet advances toward the transport nip.

摘要： An ink jet printer (10) having a print head (14) for directing an ink jet toward a sheet of paper (16) includes automatic print head spacing apparatus (80) that holds the print head apart from the sheet of paper by a preselected distance. In a preferred embodiment, the printer includes a rotatable drum (20) for supporting the sheet of paper and media securing system (24) of a first predetermined thickness for securing the paper to the drum. The print head is positioned at the preselected distance after a major surface (130) of the print head engages and is pushed back by the media securing system.

摘要： A particulate filter (16) is provided within an inlet channel (22) of an ink jet (14). The filter is oriented generally in the direction of ink flow to provide a greater filter surface area. Positioning the filter within the inlet channel results in reduced acoustic crosstalk, more effective filtering, and more efficient purging of the filter itself because of the relatively high ink pressure drop across the filter in the channel. Positioning the channel vertically assists the buoyancy of the bubble movement during operation and purging.

摘要： An ink jet print head cleaning and maintenance system has a purge chamber for applying a vacuum to a nozzle orifice surface. A specialized baffle diverts ink entering the purge chamber away a vent port through which the vacuum is drawn. An elongated wipe engages and wipes the orifice surface and is preferably moved at an extremely slow rate across the surface to enhance the wiping operation. An air knife directs a narrow stream of air across a portion of the nozzle orifice surface with air from the air stream being scanned across the surface for cleaning purposes. A specialized drip edge is positioned beneath the orifice surface for directing drops of ink away from the ink jet print head, the drops of ink being generated during the cleaning procedures. A mechanically simple cam mechanism coupled to a rotatable drum of the printer may be used to shift the maintenance system against the nozzle orifice surface for cleaning purposes.

摘要： An improved method for providing a continuous supply of liquid ink to an ink jet print head is provided. The method maintains an estimate in a memory source of the amount of liquid in a reservoir that is available to the print head. The estimate is periodically updated by information received from an ink sensor in the reservoir. By comparing the estimate to a plurality of ranges, the method determines whether additional ink may be added to the reservoir.

摘要： A method and apparatus for deskewing a sheet of media traveling through a paper path in a printer is provided. A buckle is formed in the sheet of media by over-driving the sheet into stationary deskew rollers that form a deskew nip downstream. A deskewing bias element includes a plurality of articulated segmented surfaces that contact the buckle and urge the leading edge of the sheet into the deskew nip. The buckle force combined with the biasing force from the deskewing bias element aligns the leading edge of the sheet with the deskew nip across the full width of the sheet, thereby removing any skew.
