摘要： A method of fabricating a liquid emission device includes a chamber having a nozzle orifice. Separately addressable dual electrodes are positioned on opposite sides of a central electrode. The three electrodes are aligned with the nozzle orifice. A rigid electrically insulating coupler connects the two addressable electrodes. To eject a drop, an electrostatic charge is applied to the addressable electrode nearest to the nozzle orifice, which pulls that electrode away from the orifice, drawing liquid into the expanding chamber. The other addressable electrode moves in conjunction, storing potential energy in the system. Subsequently the addressable electrode nearest to the nozzle is de-energized and the other addressable electrode is energized, causing the other electrode to be pulled toward the central electrode in conjunction with the release of the stored elastic potential energy. This action pressurizes the liquid in the chamber behind the nozzle orifice, causing a drop to be ejected from the nozzle orifice.

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： An apparatus for printing an image is provided. The apparatus includes an ink droplet forming mechanism operable to selectively create a stream of ink droplets having a plurality of volumes and a droplet deflector having a gas source. The gas source is positioned at an angle with respect to the stream of ink droplets and is operable to interact with the stream of ink droplets thereby separating ink droplets having one of the plurality of volumes from ink droplets having another of the plurality of volumes. The ink droplet producing mechanism has a nozzle and includes a heater positioned proximate to the nozzle. The heater may be selectively actuated at a plurality of frequencies to create the stream of ink droplets having the plurality of volumes. The heater may include an electrical resistance heating element. The gas source may be a positive pressure air source positioned substantially perpendicular to the stream of ink droplets.

摘要： Apparatus and process for controlling ink in a continuous ink jet printer in which a continuous stream of ink is emitted from a nozzle includes a droplet generator which causes the stream to break up into a plurality of droplets with an adjustable drop break off position having at least (1) a first drop break off position spaced from the nozzle and (2) a second drop break off position spaced from the first drop break off position. A stream deflector adjacent to the stream between the first drop break off position and the second drop break off position controls the direction of the stream between a print direction and a non-print direction. A charging apparatus is associated with the ink delivery channel to electrically charge the ink stream. 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.

摘要： An apparatus and method for drying a receiver media (30) in an ink jet printer. The apparatus generally comprises a means for creating a pressure differential between the upper surface (20) and the lower surface (50) of the receiver media (30), wherein the pressure at the lower surface (50) of the receiver media (30) is lower than the pressure at the upper surface (20) of the receiver media (30). The pressure differential-creating means may include a vacuum pump (70) adapted to generate a vacuum at the lower surface (50) of the receiver media (30) or an air pump (130) adapted to pass air currents (140) across the lower surface (50) of the receiver media (30) to cause a “Bernoulli effect”. The method generally comprises the steps of depositing ink droplets (10) onto the upper surface (20) of the receiver media (30); and creating a pressure differential between the upper surface (20) and the lower surface (50) of the receiver media (30), whereby carrier fluid contained in ink droplets (10) is drawn through the receiver media (30) from the upper surface (20) to the lower surface (50).
