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 can include an electrode layer and a mechanical member. The electrode layer can include a removed portion that is free of a landing pad. The mechanical member can be positioned in proximity to the electrode layer so as to provide a gap therebetween. The mechanical member can further include a dimple structure protruding out into the gap and aligned with the removed portion of the electrode layer. When in operation, the mechanical member can be capable of deflecting toward the electrode layer. The electrostatic actuator can be used in a fluid drop ejector for ink jet recording or printing devices.

摘要翻译： 本申请涉及静电致动器以及制造静电致动器的方法。 在一个实施例中，本申请的静电致动器可以包括电极层和机械构件。 电极层可以包括没有着陆垫的去除部分。 机械构件可以位于电极层附近，以便在它们之间提供间隙。 机械构件还可以包括突出到间隙中并与电极层的去除部分对准的凹坑结构。 当操作时，机械构件能够朝向电极层偏转。 静电致动器可用于喷墨记录或打印装置的液滴喷射器。

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.
