Liquid film moving over solid catcher surface

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.
