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.

A drop forming mechanism is positioned relative to the nozzle array. The drop forming mechanism is operable in a first state to form ink drops having a first volume travelling along a path and in a second state to form ink drops having a second volume travelling along the path. A system applies force to the ink drops travelling along the path. The force is applied in a direction such that the ink drops having the first volume diverge from the path and at least one of the ink drops having the first volume and the ink drops having the second volume are displaced relative to the length dimension.

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.

摘要： For an inkjet printhead (10) having at least one nozzle (24) and a nozzle opening (26) in the nozzle (24), a disk (28) having an off-center aperture (38) about the disk axis (X, Y) positioned over the nozzle opening (26), a system and method of compensating for the effects of defects in the inkjet printhead (10) to alter the direction of ink drops (37) ejected from the nozzle (24). Initially, the printhead (10) is tested to determine the amount of compensation desired in the direction of ink (34) ejected from the nozzle opening (26). The method comprises the step of applying heat to at least one finger-like actuator (42), causing the thermal actuator (42) to deform semi-permanently. The method further comprises the step of sliding the disk (28) over the nozzle (24) so that the off-center aperture (38) traverses the nozzle opening (26) and causes the ink (34) ejected from the nozzle opening (26) to be deflected with regard to the desired amount of compensation. Once the disk (28) has been adjusted accordingly, the application of heat is ceased, causing the thermal actuator (42) to hold the disk (28) in the desired position.

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.
