Embodiment Construction

[0019] Reference will now be made in detail to the exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

[0020] As used herein, unless otherwise indicated, the term "printer" encompasses any device that performs a printout function for any purpose, such as a digital copier, book-finishing machine, facsimile machine, multifunction machine, electrophotographic equipment, and the like. A "node" is a point or line on a film or membrane that does not deflect during operation of the printhead, where a node is the closest adjacent non-node or line on a film or membrane that flexes during operation of the film or membrane point or line.

[0021] Embodiments of the present invention may provide methods and structures for electrostatically actuated inkjet printheads with improved resistance to the negative eff...

Abstract

The present invention provides an electrostatic inkjet printhead having an electrostatic actuator with improved resistance to the adverse effects of misalignment of a bulk layer to a gap spacer layer. In an embodiment, the first and second portions of the gap isolation layer each have a first width and the first and second sections of the body each have a second width that is wider than the first width. Even with a certain amount of misalignment, the first and second sections of the bulk layer define nodes of the actuator film, thereby maintaining the effective width (WE) of the actuator film equal to the target width of the actuator film (WT).

Description

technical field [0001] The present invention relates to the field of inkjet printing devices, and more particularly, to methods and structures for electrostatically actuated inkjet printheads and printers comprising electrostatically actuated inkjet printheads. Background technique [0002] Drop-on-demand inkjet technology is widely used in the printing industry. Printers using drop-on-demand technology may use multiple (ie, arrays) of electrostatic, piezoelectric, or thermal actuators to eject ink from multiple nozzles in an orifice plate. In electrostatic spraying, each electrostatic actuator formed on the substrate assembly typically includes a flexible diaphragm or membrane, an ink chamber between the orifice plate and the membrane, and an ink chamber between the actuator membrane and the substrate assembly. air chamber. The electrostatic actuator also includes actuator electrodes formed on the substrate assembly. When a voltage is applied to activate the actuator ele...
