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： A printhead includes a jetting module that forms liquid drops travelling along a first path. A deflection mechanism causes selected liquid drops formed by the jetting module to deviate from the first path and begin travelling along a second path. A catcher includes a stationary porous surface. A liquid film flows over the stationary porous surface of the catcher. The catcher is positioned relative to the first path such that the liquid drops travelling along one of the first path and the second path contact the liquid film.

摘要： A printhead includes a catcher and a negative pressure source. The catcher includes a liquid drop contact structure. The liquid drop contact structure includes a plurality of pores, each of the plurality of pores having a substantially uniform size when compared to each other. The plurality of pores have a critical pressure point above which air can displace liquid from the plurality of pores. The negative pressure source is in fluid communication with the plurality of pores of the liquid contact structure. The negative pressure source includes a pressure regulator to control the negative pressure such that the negative pressure remains below the critical pressure point of the plurality of pores of the liquid drop contact structure.

摘要： A printhead includes a jetting module that forms liquid drops travelling along a first path. A deflection mechanism causes selected liquid drops formed by the jetting module to deviate from the first path and begin travelling along a second path. A catcher includes a liquid outlet, a stationary surface, and a liquid source that causes a liquid film to exit the liquid outlet and flow over the stationary surface of the catcher. The catcher is positioned relative to the first path such that the liquid drops travelling along one of the first path and the second path contact the liquid film.
