    摘要: An imaging apparatus capable of inhibiting inadvertent ejection of a satellite ink droplet and method of assembling same. The imaging apparatus comprises a print head transducer including a pair of sidewalls defining a chamber therebetween, the channel having the ink body disposed therein. The transducer is in fluid communication with the ink body for inducing a first pressure wave in the ink body in order to eject an ink droplet. A waveform generator is connected to the transducer for supplying voltage waveforms to the transducer, so that the transducer induces pressure waves in the ink body. However, the first pressure wave has a reflected portion formed by the first pressure wave reflecting from the sidewalls. The reflected portion is sufficient to otherwise inadvertently eject unintended satellite ink droplets. Thus, a sensor is in fluid communication with the ink body for sensing the reflected portion and is connected to the transducer for inducing a second pressure wave in the ink body. The second pressure wave has an amplitude and phase damping the reflected portion of the first pressure wave in order to the inhibit inadvertent ejection of satellite ink droplets.

    摘要: Pagewidth image forming system and method. The system features a plurality of mechanically isolated transducers capable of pressurizing an ink body associated with each of plural nozzle so that an ink meniscus extends from the ink body. The transducers are operated such that the ink bodies are uniformily intermittently pressurized. An ink droplet separator is also provided for lowering surface tension of the meniscus. In this regard, the droplet separator lowers the surface tension of the meniscus at a selected nozzle as the meniscus extends from the ink body, so that the meniscus forms a neck portion thereof. The extended meniscus severs from the ink body at the neck portion as the droplet separator lowers the surface tension to a predetermined value so as to form an ink droplet.

    摘要: An imaging apparatus capable of suppressing inadvertent ejection of a satellite ink droplet and method of assembling the apparatus. The imaging apparatus comprises a print head transducer including a pair of sidewalls defining a chamber therebetween, the channel having an ink body disposed therein. The transducer is capable of inducing a first pressure wave in the ink body in order to eject an intended ink droplet. A waveform generator is connected to the transducer for supplying a voltage waveform to the transducer, so that the transducer induces pressure waves in the ink body to eject the ink droplet. However, the first pressure wave has a reflected portion formed by the first pressure wave reflecting from the sidewalls. The reflected portion is sufficient to inadvertently eject unintended satellite ink droplets following ejection of the intended ink droplet. To avoid formation of satellite ink droplets, a sensor is in fluid communication with the ink body for sensing the reflected portion. A feedback circuit interconnects the transducer and the sensor for inducing a second pressure wave in the ink body in response to the reflected portion sensed by the sensor. The second pressure wave has an amplitude and phase damping the reflected portion of the first pressure wave in order to the suppress inadvertent ejection of the satellite ink droplets.

    摘要: Self-cleaning printer system with reverse fluid flow and method of assembling the printer system. The printer system 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. Contaminant 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 contaminant from the surface and/or orifice. The cleaning assembly includes a septum disposed opposite the surface or orifice for defining a gap therebetween. Presence of the septum accelerates the flow of fluid through the gap to induce a hydrodynamic shearing force in the fluid. 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, the print head itself has integral passageways formed therein for conducting the flow of fluid to the surface of the print head.
