摘要： Imaging apparatus includes a printhead with one or more nozzles, wherein heaters are positioned proximate to the nozzles. Electrical activation of the heaters creates ink droplets having a plurality of volumes. The use of higher-energy pulses in the portion of the waveform of heater activation associated with the formation of small drops results in more constant relative drop velocities and consequently, improved image quality. The printing apparatus also contains a droplet deflector having a gas source positioned at an angle with respect to the stream of droplets thereby separating ink droplets having one of the plurality of volumes from ink droplets having another of the plurality of volumes. An ink guttering structure is provided for capturing one range of ink-drop volumes, while allowing another volume range to strike an image receiver.

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： 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： 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; a drop generator which causes the stream to break up into a plurality of drops at a position spaced from the ink stream generator; and a drop deflector. The drop generator includes a 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 partially control the direction of the stream. The drop deflector includes a gas flow source producing an additional control to the stream between a print direction and a non-print direction.

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.

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.
