摘要： A continuous stream ink jet printer is provided having an ink droplet forming mechanism (3) for ejecting a stream of ink droplets having a selected one of at least two different volumes toward a print medium, a droplet deflector (45) for producing a flow of gas that interacts with the ink droplet stream to separate droplets having different volumes, and a gas flow conditioner (55) for preconditioning the gas flow produced by the deflector with a solvent vapor. The provision of a solvent vapor in the gas flow prevents or at least reduces changes in ink viscosity which could otherwise interfere with the recycling and filtering of ink droplets captured by the gutter of the printer.

摘要： An apparatus for printing an image is provided. The apparatus includes a source (14) of ink. A droplet forming mechanism (22) is operable in a first state to form droplets from the source having a first volume traveling along a first desired path and in a second state to form droplets from the source having a second volume traveling along the first desired path. The droplet forming mechanism is positioned proximate the source. A first system (23) selectively applies a first force to the source such that selected droplets formed from the source by the droplet forming mechanism travel along a second desired path. The first system is positioned proximate the source. A second system (40) applies a second force to the droplets traveling along at least one of the first desired path and the second desired path. The second force is applied in a direction such that the droplets having the first volume diverge from the droplets having the second volume.

摘要： Apparatus for controlling ink in an ink jet printer includes a print head (16) of the type wherein ink forms a meniscus above a nozzle bore (46) and spreads along an upper surface of the print head. The print head (16) includes a substrate (104) having an upper surface; an ink delivery channel (102) 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 (50) lies about at least a portion of the nozzle bore, the heater (50) having an upper surface which is coplanar with a surrounding portion of the upper surface of the substrate (104), whereby the print head is flat in regions along an ink-to-solid contact line of the meniscus.

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： A continuous ink jet printing system using asymmetrical heating of the fluid in which the nozzle bore (46, 76, 78) of the printhead preferably has a non-circular opening. The nozzle bore (46, 76, 78) has reflection symmetry about the long axis of its cross-section and may be, for example, elliptical or rectangular. In the preferred embodiment of the invention, the nozzle bore (46, 76, 78) has an aspect ratio greater than unity, wherein the aspect ratio is defined as the ratio of the long axis length to the short axis length. A heater (50, 50', 50") used to generate deflection of the fluid exiting the nozzle bore (46, 76, 78) generally conforms to the perimeter of the nozzle bore (46, 76, 78) such that the heated portion is along the long dimension of the nozzle bore (46, 76, 78).

摘要： Apparatus is disclosed for controlling ink in a continuous ink jet printer (16) 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 (80) includes a body having a surface positioned adjacent to the stream (60) between the ink stream generator and the position whereat the stream breaks up into droplets (66,67) 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.
