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： A liquid ejection device includes a jetting module including an array of nozzles; a thermal stimulation device associated with each nozzle of the array of nozzles; and a controller in electrical communication with each thermal stimulation device. The controller is configured to provide a first activation waveform to each thermal stimulation device and to provide a second activation waveform to each thermal stimulation device to clean the associated nozzle with liquid emitted from the associated nozzle. The second activation waveform has a higher activation component when compared to the first activation waveform.

摘要： An apparatus for printing an image is provided. The apparatus includes an ink droplet forming mechanism operable to selectively create a stream of ink droplets having a plurality of volumes traveling along a first path. A droplet deflector is positioned at an angle with respect to the stream of ink droplets. The droplet deflector includes a gas flow operable to interact with the stream of ink droplets such that ink droplets having one of the plurality of volumes begin traveling along a second path and ink droplets having another of the plurality of volumes begin traveling along a third path. At least a portion of a catcher including a porous material is at least partially positioned in one of the first, second, and third paths.

摘要： A cleaning system for a continuous inkjet printer comprises a cleaning chamber positioned substantially parallel to an ink supply chamber and nozzle plate, and a gas supply, such as air or nitrogen. The cleaning chamber is formed by a cover and the nozzle plate, wherein the gas is routed between the cover and the nozzle plate so as to remove debris and excess ink from the inkjet nozzles and surrounding area. A fluid may also be applied in addition to the gas, and a deflector may be positioned on the cover to increase the angle of incidence of air and fluid as it contacts the inkjet nozzles and surrounding area.

摘要： Both a cleaning fluid jet apparatus and method for cleaning an array of inkjet nozzles in a printhead is provided. The fluid jet apparatus includes a cleaning head having an array of cleaning nozzles registrable with the array of inkjet nozzles in the printhead, and a mounting assembly that mounts the cleaning head in opposition to the printhead with the cleaning nozzles in substantial alignment with the inkjet nozzles. A supply of pressurized cleaning fluid is connected to the cleaning nozzles such that the cleaning nozzles discharge a stream of high velocity cleaning droplets that impinges the inkjet nozzles. Both a droplet sizing mechanism and a droplet speed controller are provided so that the size, frequency, and velocity of the cleaning droplets may be selected for maximum cleaning efficiency. The apparatus also includes a mechanism for changing a location of cleaning droplet impingement so that both the inkjet nozzles and the areas immediately surrounding the nozzles may be effectively cleaned.
