摘要： A continuous inkjet printer in which a continuous ink stream is deflected at the printhead nozzle bore without the need for charged deflection plates or tunnels. The printhead includes a primary ink delivery channel which delivers a primary flow of pressurized ink through an ink staging chamber to the nozzle bore to create an undeflected ink stream from the printhead. A secondary ink delivery channel adjacent to the primary channel is controlled by a thermally actuated valve to selectively create a lateral flow of pressurized ink into the primary flow thereby causing the emitted ink stream to deflect in a direction opposite to the direction from which the secondary ink stream impinges the primary ink stream in the ink staging chamber. A method of fabricating the printhead includes layering of the thermally actuated valve over the secondary ink delivery channel formed in a silicon substrate and creating the ink staging chamber over the delivery channels with sacrificial material which is later removed through the nozzle bore etched into the chamber wall formed over the sacrificial material.

摘要： A continuous ink jet print head is formed using a combination of traditional CMOS technology to form the various controlling electrical circuits on a silicon substrate having insulating layer(s) which provide electrical connections and a MEMS technology for forming nozzle openings. A blocking structure is formed in the insulating layer(s) between a first ink channel formed in the silicon substrate and a second ink channel formed in the insulating layer(s). The blocking structure causes ink to flow around the blocking structure and thereby develop lateral flow components to the liquid entering the second channel so that, for droplets selected for printing, as the stream of droplets emanates from the bore of the nozzle, there is provided a reduced amount of heat needed for operating a heating element adjacent each nozzle opening.

摘要： An asymmetric heat-type inkjet printer includes an inkjet printhead having at least one nozzle for continuously ejecting a stream of ink that forms a train of ink droplets, a heater disposed adjacent to the nozzle for selectively thermally deflecting the droplet forming stream of ink either toward a printing medium, or an ink gutter that captures and recirculates the ink. To increase the angle of deflection that the intermittently operated heater imposes on the droplet-forming stream of ink, a steering fluid assembly is provided in communication with the inkjet nozzle for co-extruding a thin film of fluid around the ink which has a higher volatility and a lower thermal diffusivity than the liquid forming the ink. When the ink is water based, the steering fluid may be, for example, polyethylene oxide based surfactant, or isopropanol. The invention allows water-based ink droplets in such printers to be deflected at greater angles in response to heat pulses generated by the heater, thereby enhancing printing accuracy and speed.

摘要： A pump includes two opposing plates having a space there between to define a secondary fluid passage. A first aperture is formed through the first plate and a second aperture is formed in the second plate to define a primary fluid channel extending across the secondary fluid channel. A heater on the second plate moves primary fluid through the primary fluid channel due to the Marangoni type effect. A heater on the first plate causes a meniscus to enlarge to thereby form a drop of fluid ejected out of the primary fluid channel.

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： Self-cleaning printer with reverse fluid flow 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. 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 an oscillatable septum disposed opposite the surface or orifice for defining a gap therebetween. Presence of the oscillatable 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.
