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.

摘要： A self-cleaning printer includes a print head having a surface that is susceptible to a contaminate build up. A cleaning liquid containing a concentration of macroscopic cleaning particles is flowed in frictive contact with the contaminate such that a combined effect of frictive force and hydrodynamic shearing force acting on the contaminate effectively removes the contaminate from the surface. Preferably, the cleaning particles are adapted to attach to the contaminate. They may include polymeric beads such as polystyrene spheres. The cleaning particles preferably have surfaces to which polymeric chains are attached, the polymeric chains having end groups which adhere to the contaminate.

摘要： A method of manufacturing a pump [10] for pumping various primary fluids. A body is formed from silicon dies [102,104]. A primary fluid channel [110] is formed in the body and a primary fluid supply [122] is coupled to the primary fluid channel [110] to supply a primary fluid to the primary fluid channel [110]. A mechanism for introducing a secondary fluid to an interface region of the primary fluid channel [110] is formed in the body. An energy delivery device is formed in the body to deliver energy to an interface between region between the primary fluid and the secondary fluid to create a thermal gradient along the fluid interface. The thermal gradient results in a surface tension gradient along the interface. The primary fluid will move to compensate for the surface tension gradient. Various semiconductor fabrication processes can be used to form the elements on the body.

摘要： A droplet generator is provided that is particularly adapted for generating micro droplets of ink on demand in an inkjet printhead having a plurality of nozzles. The droplet generator includes a droplet separator formed from the combination of a droplet assistor and a droplet initiator. The droplet assistor is coupled to ink in each of the nozzles and functions to lower the amount of energy necessary for an ink droplet to form and separate from an ink meniscus extending across the nozzle outlet. The droplet assistor may be, for example, a heater or surfactant supply mechanism for lowering the surface tension of the ink meniscus. Alternatively, the droplet assistor may be a mechanical oscillator such as a piezoelectric transducer that generates oscillations in the ink sufficient to periodically form convex ink meniscus across the nozzle outlets, but insufficient to cause ink droplets to separate from the outlets. The droplet initiator cooperates with the droplet assistor and selectively causes an ink droplet to form and separate from the ink meniscus. The droplet initiator may be, for example, a thermally-actuated paddle. The droplet separator increases the speed and accuracy of ink micro droplets expelled from the printhead nozzles.

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： Image forming system and system. The method comprises a transducer for pressurizing and depressurizing an ink body so that an ink meniscus alternately extends from the ink body as the ink body is pressurized to form a neck portion thereof and retracts as the ink body is depressurized. An ink droplet separator is is in communication with the neck portion of the meniscus for lowering surface tension of the neck portion of the meniscus. In this regard, the droplet separator lowers the surface tension of the meniscus as the meniscus extends from the ink body. The extended meniscus severs from the ink body to form an ink droplet as the droplet separator lowers the surface tension of the neck portion to a predetermined value and as the ink meniscus retracts during depressurization of the ink body.

摘要： Self-cleaning printer system with reverse fluid flow and rotating roller 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 rotatable roller disposed opposite the surface or orifice and defining a gap therebetween. Presence of the rotating roller 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.
