摘要： Apparatus is disclosed for controlling ink in a continuous ink jet printer in which a continuous stream of ink is emitted from a nozzle, wherein an ink stream generator establishes a continuous flow of ink in a stream such that the stream breaks up into a plurality of droplets at a position spaced from the ink stream generator. A stream deflector includes a body having a surface positioned adjacent to the stream between the ink stream generator and the position whereat the stream breaks up into droplets such that the stream contacts the surface and is deflected at least in part due to a tendency of liquid to contact a surface in proportion to liquid-solid free energy. The stream may be deflected substantially totally due to a tendency of liquid to contact a surface in proportion to liquid-solid free energy, or may be deflected partially due to a tendency of liquid to contact a surface in proportion to liquid-solid free energy and partially due to a reactive force on the stream exerted by the surface as a result of collision of the stream with the surface.

摘要： A method for controlling a terminal flow of ink droplets from the nozzle of an ink jet printer at the end of a printing operation is provided. The printer has a first heating element disposed on one side of the nozzle that is selectively actuated to direct ink droplets away from a recording medium and into an ink gutter during a printing operation. The printer also has a second heating element disposed on the side of the nozzle opposite from the first heating element. After the first heating element applies its last operational heat pulse to the printing nozzle at the end of a printing operation, the second heating element applies at least one deflection correcting heat pulse of the same duration, magnitude and period as the last operational heat pumps. The method prevents ink droplets generated after the end of a printing operation from erroneously striking the printing medium.

摘要： To compensate for droplet placement errors, a continuous ink jet printer includes a heater having a plurality of selectively independently actuated sections which are positioned along respectively different portions of the nozzle bore's perimeter. An actuator selectively activates none, one, or a plurality of the heater sections such that: actuation of heater sections associated with only a portion of the entire nozzle bore perimeter produces an asymmetric application of heat to the stream to control the direction of the stream between a print direction and a non-print direction, and simultaneous actuation of different numbers of heater sections associated with only a portion of the entire nozzle bore perimeter produces corresponding different asymmetric application of heat to the stream to thereby control the direction of the stream between one print direction and another print direction.

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 to heater elements associated with a nozzle and a MEMS technology for forming ink delivery cavities or channels and bores. A blocking structure is formed in the silicon substrate between an ink channel formed in the silicon substrate and a nozzle bore formed in the insulating layer(s). The blocking structure causes ink in an ink channel to flow around the blocking structure and thereby develop lateral flow components to the liquid entering the bore so that as the stream of fluid emanates from the bore the lateral flow components are a factor in allowing an increased stream deflection under the condition of asymmetric heating.

摘要： Apparatus for controlling ink in an ink jet printer includes a print head of the type wherein ink forms a meniscus above a nozzle bore and spreads along an upper surface of the print head. The print head includes a substrate having an upper surface; an ink delivery channel below the substrate; and a nozzle bore through the substrate and opening below the substrate into the ink delivery channel to establish an ink flow path. A source of pressurized ink communicates with the ink delivery channel such that ink tends to form a meniscus on the upper surface of the heater. A resistive heater lies about at least a portion of the nozzle bore, the heater having an upper surface which is coplanar with a surrounding portion of the upper surface of the substrate, whereby the print head is flat in regions along an ink-to-solid contact line of the meniscus.

摘要： A continuous ink jet printer emits a continuous stream of ink from an ink stream generator. The stream breaks up into a plurality of droplets at a position spaced from the ink stream generator. A stream deflector includs a control surface positioned adjacent to the stream between the ink stream generator and the position whereat the stream breaks up into droplets such that the stream contacts the control surface and is thereby deflected due to a gain in free energy caused by physical contact between the ink in the stream and the control surface. Apparatus may be provided to modulate the position of the control surface to change the direction of the stream between a print direction and a non-print direction.
