摘要： A method, and apparatus for performing the method, are intended to prevent all of the ink discharged from a defective one of multiple nozzles in a continuous inkjet printhead from being used for printing on a print medium. This can be done by periodically heating the defective nozzle at a frequency that is greater than frequencies other nozzles which are not defective are periodically heated, to cause the defective nozzle to only discharge ink droplets that have a smaller volume than ink droplets discharged from the nozzles that are not defective. Then, the smaller volume droplets discharged from the defective nozzle are prevented from reaching a print medium, but the larger volume ink droplets discharged from the nozzles that are not defective are allowed to reach the print medium.
摘要翻译：用于执行该方法的方法和装置旨在防止从连续喷墨打印头中的多个喷嘴中的有缺陷的喷嘴中排出的所有墨水都用于打印介质上的打印。这可以通过周期性地加热有缺陷的喷嘴的频率来实现，该频率大于频率不同于周期性加热的其它喷嘴的频率，以使有缺陷的喷嘴仅排出具有比从喷嘴喷出的墨滴的体积更小的墨滴没有缺陷。然后，防止从有缺陷的喷嘴排出的较小体积的液滴到达打印介质，但是允许从喷嘴排出的较大体积的墨滴到达打印介质。

摘要： An ink jet print head is formed of a silicon substrate that includes an integrated circuit formed therein for controlling operation of the print head. The silicon substrate has one or more ink channels formed therein along the longitudinal direction of the noble array. An insulating layer or layers overlie the silicon substrate and has a series or an array of nozzle openings or bores formed therein along the length of the substrate and each nozzle opening communicates with an ink channel. The area comprising the nozzle openings forms a generally planar surface to facilitate maintenance of the printhead. A heater element is associated with each nozzle opening or bore for asymmetrically heating ink as ink passes through the nozzle opening or bore.

摘要： Imaging apparatus includes a printhead with one or more nozzles, wherein heaters are positioned proximate to the nozzles. Electrical activation of the heaters creates ink droplets having a plurality of volumes. The use of higher-energy pulses in the portion of the waveform of heater activation associated with the formation of small drops results in more constant relative drop velocities and consequently, improved image quality. The printing apparatus also contains a droplet deflector having a gas source positioned at an angle with respect to the stream of droplets thereby separating ink droplets having one of the plurality of volumes from ink droplets having another of the plurality of volumes. An ink guttering structure is provided for capturing one range of ink-drop volumes, while allowing another volume range to strike an image receiver.

摘要： To compensate for droplet placement errors, a continuous ink jet printer includes a heater having a plurality of selectively independently actuated sections which are positioned along respectively different portions of the nozzle bore's perimeter. An actuator selectively activates none, one, or a plurality of the heater sections such that: actuation of heater sections associated with only a portion of the entire nozzle bore perimeter produces an asymmetric application of heat to the stream to control the direction of the stream between a print direction and a non-print direction, and simultaneous actuation of different numbers of heater sections associated with only a portion of the entire nozzle bore perimeter produces corresponding different asymmetric application of heat to the stream to thereby control the direction of the stream between one print direction and another print direction.

摘要： Apparatus is disclosed for controlling ink in a continuous ink jet printer in which a continuous stream of ink is emitted from a nozzle, wherein an ink stream generator establishes a continuous flow of ink in a stream such that the stream breaks up into a plurality of droplets at a position spaced from the ink stream generator. A stream deflector includes a body having a surface positioned adjacent to the stream between the ink stream generator and the position whereat the stream breaks up into droplets such that the stream contacts the surface and is deflected at least in part due to a tendency of liquid to contact a surface in proportion to liquid-solid free energy. The stream may be deflected substantially totally due to a tendency of liquid to contact a surface in proportion to liquid-solid free energy, or may be deflected partially due to a tendency of liquid to contact a surface in proportion to liquid-solid free energy and partially due to a reactive force on the stream exerted by the surface as a result of collision of the stream with the surface.
