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： Apparatus for controlling ink in a continuous ink jet printer includes an ink delivery channel; a source of pressurized ink communicating with the ink delivery channel; a nozzle bore which opens into the ink delivery channel to establish a continuous flow of ink in a stream, the nozzle bore defining a nozzle bore perimeter; and a heater which causes the stream to break up into a plurality of droplets at a position spaced from the nozzle bore. The heater having a selectively-actuated section associated with only a portion of the nozzle bore perimeter, whereby actuation of the heater section 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.

摘要： Both an inkjet printer and method are provided for controlling inkjet printing on a receiver. The inkjet printer includes a printhead having at least one nozzle for ejecting a stream of ink droplets, a droplet deflector for generating a flow of gas that impinges on the stream of ejected droplets to deflect the trajectories of the droplets, and a controller for varying the velocity of the gas flow in order to vary the degree of trajectory deflection so the droplets intended to print on a particular pixel in the receiver land on top of one another without elongation despite relative movement between the printhead and the receiver. The printer provides improved image quality and productivity while reducing image artifacts.

摘要： An apparatus for printing an image is provided. The apparatus includes a source of ink. A droplet forming mechanism 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 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 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： An ink jet printer having an array of nozzles from which ink droplets of adjustable volume are emitted further includes a mechanism adapted to individually adjust the volume of the emitted ink droplets. The mechanism has a first state wherein the emitted droplets of selected nozzles are of a predetermined small volume and a second state wherein the emitted droplets of selected nozzles are of a predetermined large volume. A controller selectively switches the mechanism between its first and its second states such that ink droplets of the predetermined large volume are not simultaneously emitted from adjacent ones of the nozzles.

The stream deflector includes at least one deflection electrode; and a deflection control circuit is adapted to apply a constant DC voltage to the deflection electrode to deflect droplets from one of the print and non-print directions to the other of the print and non-print directions.
