Multiple thin film piezoelectric elements driving single jet ejection system
Abstract:
A printhead including a plurality of actuators, wherein each actuator of the plurality of actuators includes a plurality of drive electrodes, a plurality of diaphragms, and a single nozzle. Each drive electrode is uniquely paired with one of the diaphragms. In an embodiment, the printhead may be configured so that all drive electrodes for a single actuator always activate simultaneously to eject ink from the single nozzle. In another embodiment, the printhead may be configured so that each drive electrode of the plurality of drive electrodes for a single actuator are individually addressable and may be fired independently of the other drive electrodes of the single actuator.
