摘要： A continuous ink jet print head is formed of a silicon substrate that includes integrated circuits formed therein for controlling operation of the print head. An insulating layer or layers overlies 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 is formed in a recess in the insulating layer or layers by a material depletion process such as etching. The process of etching defines the nozzle openings at locations where heater elements are formed in the insulating layer or layers during a conventional CMOS processing of the integrated circuits. The print head structure thereby provides for minimal post processing of the print head after the completion of the CMOS processing.

摘要： A printer having mechanically-assisted ink droplet separation and method of using same, for separating an ink meniscus from an ink nozzle orifice while clearing-away particulate matter from about the orifice. In a preferred embodiment of the invention, a heater surrounds an orifice formed by the nozzle, the orifice having an ink meniscus residing therein. As the heater heats the ink meniscus, surface tension of the ink meniscus decreases, thereby causing the ink meniscus to extend outwardly from the orifice to define an extended ink meniscus. A cutter, which is disposed near the orifice, includes a plate member disposed opposite an outside surface of the nozzle so as to define a passage between the outside surface and the plate member. The plate member has an opening aligned with the orifice and in communication with the passage. A gas pressure regulator in communication with the passage supplies pressurized gas into the passage, which gas flows along the passage an through the opening. As the gas flows through the opening, it impinges the extended ink meniscus to separate the extended ink meniscus from the orifice. As the extended ink meniscus separates from the orifice, it forms an ink droplet that travels to a receiver medium, so that an ink spot is placed onto the receiver medium. Moreover, as the gas flows through the opening, the gas clears-away particulate matter from about the orifice.
