摘要： An ink jet printer for printing in a wide format includes a plurality of ink jet print heads for producing rows of regularly spaced apart ink jets. The print heads are supported and located by first and second print head carriages that are controllably moveable to locate the print heads to within a fraction of an ink jet spacing in directions both parallel with and perpendicular to the direction of movement of the print medium. The first and second carriages are spaced apart along the direction of relative movement of the print medium by a distance sufficient to permit the first and second print heads to be arranged in an interleaved relation, or an end to end relation.

摘要： A printing system using multiple printheads maintains color consistency between the printheads by printing a first color patch (102) with a first color with a plurality of printheads (30) at a first pressure and with a first pixel fill coverage. A second color patch (104) is printed with the first color with the plurality of printheads at a second pressure with the first pixel fill coverage. The print density of the first patch and the second patch is measured for each of the plurality of printheads and the print density for each of the plurality of printheads is compared. A pressure for each of the plurality of printheads is adjusted to compensate for differences in density between the first patch and the second patch for each of the printheads.

摘要： A printhead includes a jetting module, a catcher, a drop deflection mechanism, and a capping mechanism. The jetting module includes an array of nozzles and is operable to form liquid drops from liquid emitted through the nozzles of the nozzle array. The catcher collects some of the liquid drops. The drop deflection mechanism deflects the liquid drops such that some of the liquid drops contact the catcher while other liquid drops are allowed to contact a print media. The capping mechanism includes a capping member located between the nozzle array of the jetting module and the drop deflection mechanism. The capping member has a first position covering the nozzle array and a second position removed from the nozzle array.

摘要： A drop generator is operated to form large-volume and small-volume droplets by providing a droplet generator having a nozzle and an adjustable stimulation device; supplying liquid to the droplet generator such that a stream of diameter D emanates from the nozzle; activating the stimulation device to produce a first set of perturbations on the liquid stream, the perturbations having a period x such as to cause the liquid stream to form into small-volume droplets; selectively adjusting the stimulation device to produce a second set of perturbations on the liquid stream, the second set of perturbations having a period Nx such as to cause a segment of the liquid stream to form into a large-volume droplet, whereby the large-volume droplet is N times the volume of the small-volume droplets; and further adjusting the stimulation device to produce a third set of perturbations on the liquid stream during the period Nx.

摘要： A system and method are provided for cleaning the printhead of a continuous ink jet printing system. A cleaning fluid is introduced and used to flush ink residues and debris from the interior of the drop generator, the exterior of the orifice plate, the charge plate face and the catcher face. This system and method removes dried ink residues and other debris and deposits by providing a cleaning fluid with a low surface tension to dissolve or flush away the unwanted material from the orifices. This is particularly advantageous in that the flushing and rinsing is accomplished without mechanical contact which could abrade or damage the orifices.

摘要： A jetting module is provided for installation in a printhead including mounting features, fluid and electrical connections, and at least a portion of a drop deflection mechanism. The jetting module includes a nozzle plate, mounting features, and fluid and electrical connections. The mounting features of the jetting module are configured to engage the mounting features of the printhead. The fluid and electrical connections of the jetting module correspond to the fluid and electrical connections of the printhead. The fluid and electrical connections of the jetting module are located relative to the mounting features of the jetting module such that a force applied to couple the fluid and electrical connections of the jetting module and the fluid and electrical connections of the printhead provides force to maintain contact between the mounting features of the jetting module and the mounting features of the printhead.

摘要： The turbulence of the air moved through an inkjet print head enclosure is reduced before reaching the printing region between the print head and a print medium by positioning a HEPA filtration system between an air inlet opening in the enclosure and the print head. Turbulence is removed from air moved through the air path by HEPA filtration of the air being drawn into the print head enclosure before reaching the printing region.
