Abstract
A printhead includes a substrate, catcher, and monolithic liquid jetting structure including a nozzle and deflection mechanism. A liquid jet is ejected through the nozzle in a direction substantially parallel to a first surface of the substrate. The nozzle includes material layers formed on the first surface of the substrate. At least one of the material layers of the nozzle includes a drop forming mechanism actuated to form liquid drops from the liquid jet. The deflection mechanism is associated with the liquid jet and deflects portions of the liquid jet between first and second paths. The liquid drops formed from portions of the liquid jet following the first path and second path continue to follow the first path and second path, respectively. The catcher includes a liquid drop contact surface including a portion of the first surface of the substrate and collects liquid drops following the second path.
