摘要： Systems and methods of ejecting ink drops from an inkjet printer are disclosed. The systems and methods can include a printhead with one or more actuators with associated nozzles and membranes. A voltage waveform can be applied to the actuators to fill the actuators with a volume of ink and eject the ink through the nozzles as ink drops. The voltage waveform can have associated pre-fill voltage to fill the actuator with ink and a firing voltage to eject the ink. The actuator membranes can have multi-height dimples to protect the membranes from contacting electrodes and reduce the electric field.

摘要： The present application is directed to electrostatic actuators, and methods of making electrostatic actuators. In one embodiment, an electrostatic actuator of the present application comprises a first electrode and a second electrode. The second electrode is positioned in proximity to the first electrode so as to provide a gap between the first electrode and the second electrode. The first electrode is capable of being deflected toward the second electrode. A dielectric structure comprising a dielectric landing post is positioned in the gap between the first electrode and the second electrode, the dielectric structure extending over a greater surface of the gap than the landing post. The landing post protrudes out into the gap so as to limit the minimum contact spacing between the first electrode and the second electrode.

A piezoelectric element array for an ink jet print head can include a plurality of piezoelectric elements spaced from adjacent piezoelectric elements by an interstitial space. Each piezoelectric element can include a central void space formed in a first intermediate layer between the piezoelectric element array and a second intermediate layer that is operable to function as a free space for portions of the piezoelectric elements to actuate into when subjected to the voltage.

The nozzle plate includes a nozzle hole and a group of priming holes, the priming holes configured to maintain a substantially ink free surface on the nozzle plate during a freeze thaw cycle of ink in the ink chamber. A method for accommodating expansion and contraction of ink during a freeze thaw cycle of ink in an ink chamber is also provided. The method includes providing a group of priming holes in a nozzle plate of the ink chamber, the group of priming holes maintaining a substantially ink free surface on the nozzle plate during the freeze thaw cycle.
