摘要： A continuous ink jet apparatus is provided. The printhead includes a nozzle array with portions of the nozzle array defining a length dimension. 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： A method of printing includes associating a pixel area of a recording medium with a nozzle and a time interval during which a fluid drop ejected from the nozzle can impinge the pixel area of the recording medium. The time interval is divided into a plurality of subintervals. Some of the plurality of subintervals are grouped into blocks. One of two labels is associated with each block. The first label defines a printing drop and the second label defines non-printing drops. No drop forming pulse is associated between subintervals of each block having the first label. A drop forming pulse is associated between each subinterval of each block having the second label. A drop forming pulse is associated between other subintervals between each pair of consecutive blocks. Drops are caused to be ejected from the nozzle based on the associated drop forming pulses.
