摘要： A continuous inkjet printing apparatus is provided. The apparatus includes a printhead having a two dimensional nozzle array. The two dimensional nozzle array includes a first nozzle row being disposed in a first direction and a second nozzle row being disposed displaced and offset relative to the first nozzle row. A drop forming mechanism is positioned relative to the nozzle rows and is operable in a first state to form drops having a first volume travelling along a path and in a second state to form drops having a second volume travelling along the same path. A system applies force to the drops travelling along the path with the force being applied in a direction such that the drops having the first volume diverge from the path.

摘要： There is provided by this invention a unique printing system that utilizes a notch deflector in the ink delivery channel of a continuous ink jet printing system to control the angle of deflection ink droplets in a print and non-print direction. The width and depth of the notch in the ink delivery channel can be varied to produce different angles of deflection of the ink droplets for a given velocity of ink through the channel. Also, for any predetermined width and depth of the notch in the ink delivery channel, the deflection angle of the droplets will vary with varying velocities of ink flow. Control circuits are connected to the notch deflector to adjust the depth of the deflector for different angles of deflection.

摘要： A printer includes a printhead and a source of liquid. The printhead includes a nozzle bore. The liquid is under pressure sufficient to eject a column of the liquid through the nozzle bore. The liquid has a temperature. A thermal modulator is associated with the nozzle bore. The thermal modulator is operable to transiently lower the temperature of the liquid as the liquid is ejected through the nozzle bore. An electrical pulse source is in electrical communication with the thermal modulator. The electrical pulse source is operable to provide a series of pulses to the thermal modulator that control the transient temperature lowering of the liquid. The series of pulses includes a first pulse applied at a first power level for transferring heat to the liquid, a second pulse applied at a second power level for transferring heat to the liquid, and a third pulse applied at a third power level for transferring heat to the liquid. The third power level is in between the first power level and the second power level.

摘要： 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： For an inkjet printhead (10) with integral compensation for misdirection of ink drops (37) ejected through at least one nozzle (24) of the printhead (10), a system and method of modifying the nozzle cavity space (32a) so as to compensate for the effects of defects in the printhead (10) by altering the direction the ejected ink drops (37). The inkjet printhead (10) comprises at least one reservoir (28) integrated within the membrane (30). The inkjet printhead (10) also comprises a channel (38) extending from the reservoir (28) and terminating in the nozzle cavity (32). A hardening substance (40) within the reservoir (28) and channel (38) is a plastic material having a high thermal expansion coefficient. An internal heater (48) within the reservoir (28) and adjacent the hardening substance (40) is adapted to cause the plastic material (40) to flow in order to form a protrusion (44) of plastic material (40) within the nozzle cavity space (32a). Alternatively, the plastic material (40) can be recessed within the channel (38). Thus, the hardening substance (40) is adapted to internally alter the nozzle cavity space (32a) and cause ink (34) ejected from the nozzle opening (26) to be deflected with regard to a desired amount of compensation.
