摘要： A printing system includes a liquid drop ejector, a fluid passage, and a fluid flow source. The liquid drop ejector is operable to form liquid drops having a plurality of volumes moving along a first path. The fluid passage includes a wall. A source of acoustic energy is associated with the wall. A fluid flow source is associated with the passage and is configured to provide a fluid flow through the passage. Interaction of the fluid flow and the liquid drops causes liquids drops having one of the plurality of volumes to begin moving along a second path.

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.

摘要： A continuous drop emitter includes a liquid supply chamber containing a liquid held at a positive pressure. First and second nozzles are in fluid communication with the liquid supply chamber and emit first and second continuous streams of a liquid. First and second stream break-up transducers independently synchronize the break up of the first and second continuous streams of the liquid into first and second streams of drops. An acoustic damping material is located adjacent to or within the liquid supply chamber for damping sound waves generated within the liquid chamber by the first and second stream break-up transducer. The continuous drop emitter can be configured with a Helmholtz resonant chamber tuned to a critical stimulation frequency having an acoustic damping material located therein.
