    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 method of ejecting a drop of fluid includes providing a fluid ejector. The fluid ejector includes a substrate, a MEMS transducing member, a compliant membrane, walls, and a nozzle. The substrate includes a cavity and a fluidic feed. A first portion of the MEMS transducing member is anchored to the substrate. A second portion of the MEMS transducing member extends over at least a portion of the cavity and is free to move relative to the cavity. The compliant membrane is positioned in contact with the MEMS transducing member. A first portion of the compliant membrane covers the MEMS transducing member, A second portion of the compliant membrane being anchored to the substrate. Walls define a chamber that is fluidically connected to the fluidic feed. At least the second portion of the MEMS transducing member is enclosed within the chamber. A quantity of fluid is supplied to the chamber through the fluidic feed. An electrical pulse is applied to the MEMS transducing member to eject a drop of fluid through the nozzle.

    摘要： An ink jet print head is formed of a silicon substrate that includes an integrated circuit formed therein for controlling operation of the print head. The silicon substrate has one or more ink channels formed therein along the longitudinal direction of the nozzle array. An insulating layer or layers overlie the silicon substrate and has a series or an array of nozzle openings or bores formed therein along the length of the substrate and each nozzle opening communicates with an ink channel. The area comprising the nozzle openings forms a generally planar surface to facilitate maintenance of the printhead. A heater element is associated with each nozzle opening or bore for asymmetrically heating ink as ink passes through the nozzle opening or bore.
