摘要： Self-cleaning printer having ultrasonics and method of assembling same for cleaning a print head surface and ink ejection orifices. The printer comprises a print head defining a plurality of ink channels therein, each ink channel terminating in an ink ejection orifice. The print head also has a surface thereon surrounding all the orifices. Particulate matter may reside on the surface and also may completely or partially obstruct the orifice. Therefore, a cleaning assembly is disposed relative to the surface and/or orifice for directing a flow of fluid along the surface and/or across the orifice to clean the particulate matter from the surface and/or orifice. The cleaning assembly includes an ultrasonic transducer in communication with the fluid for generating ultrasonic vibrations causing pressure waves within the fluid. Presence of the pressure waves induces a hydrodynamic force in the fluid. This force acts against the particulate matter to clean the particulate matter from the surface and/or orifice. A pump is also provided for pumping the fluid from the surface and/or orifice as the surface and/or orifice is cleaned. As the surface and/or orifice is cleaned, the particulate matter is entrained in the fluid. A filter is provided to separate the particulate matter from the fluid.

摘要： Self-cleaning printer with reverse fluid flow and ultrasonics and method of assembling the printer. The printer comprises a print head defining a plurality of ink channels therein, each ink channel terminating in an ink ejection orifice.

Therefore, a cleaning assembly is disposed relative to the surface and/or orifice for directing a flow of fluid along the surface and/or across the orifice to clean the contaminant from the surface and/or orifice. The cleaning assembly includes a septum disposed opposite the surface or orifice for defining a gap therebetween.

This shearing force acts against the contaminant to clean the contaminant from the surface and/or orifice. A pump in fluid communication with the gap is also provided for pumping the fluid through the gap. As the surface and/or orifice is cleaned, the contaminant is entrained in the fluid. A filter is provided to separate the contaminant from the fluid. In addition, a valve system in fluid communication with the gap is operable to direct flow of the fluid through the gap in a first direction and then in a second direction opposite the first direction to enhance cleaning effectiveness. Moreover, an ultrasonic transducer induces pressure waves in the fluid to dislodge the contaminant and thus clean the surface and/or orifice.

摘要： According to one embodiment of the present invention, a print head comprises a print head body defining an interior chamber and an orifice plate. The orifice plate has an outer surface and further defines a cleaning fluid orifice through the orifice plate for conducting a flow of a cleaning fluid through the cleaning fluid orifice and onto an outer surface of said orifice plate. The orifice plate also defines a drain orifice for conducting a flow of cleaning fluid from the surface to the interior chamber. A supply of pressurized cleaning fluid is disposed in said cavity and connected to the cleaning fluid passageway. During cleaning operations, the fluid flow system defines a flow of a cleaning fluid from the passageway and onto said outer surface. The drain orifice receives cleaning fluid from the outer surface and channels the cleaning fluid into the fluid return.

摘要： The present invention comprises a self-cleaning print head having an orifice plate defining an ink jet orifice, cleaning orifice and drain orifice. The orifice plate further defines an outer surface between the orifices. The print head has a source of pressurized cleaning fluid connected to the cleaning orifice and a fluid return connected to the drain orifice for storing used cleaning fluid. During cleaning operations, the source of pressurized cleaning fluid causes cleaning fluid to flow from the cleaning orifice, and the cleaning orifice directs the flow of cleaning fluid across the outer surface and the ink jet orifice and into the drain orifice.
