Abstract: A flexible circuit for use within a printhead assembly and to connect a printhead body to an external circuit includes a substantially planar portion having one or more layers of conductive material and having a top surface substantially parallel to a top surface of the printhead body. One or more integrated circuits can be mounted onto the planar portion. Multiple leads extend from each integrated circuit, the leads electrically connected to the printhead body. One or more arms are attached to, and substantially perpendicular to, the planar portion, each arm including one or more external connectors configured to connect to the external circuit.

Abstract: A printhead assembly including one or more nozzles is described that can include a droplet ejection module. In one embodiment, the droplet ejection module includes a liquid supply assembly, a housing and a droplet ejection body. The liquid supply assembly includes a self-contained liquid reservoir and a liquid outlet. The housing is configured to permanently connect to the liquid supply assembly and includes a liquid channel configured to receive a liquid from the liquid outlet of the liquid supply assembly and to deliver the liquid to a droplet ejection body. The droplet ejection body is permanently connected to the housing and includes one or more liquid inlets configured to receive liquid from the housing and one or more nozzles configured to selectively eject droplets.

Abstract: A method of forming a microelectromechanical device with a piezoelectric transducer is described, the method comprising the steps of bonding a first surface of a body of piezoelectric material (107) to a first surface of a handle layer (135); forming alignment cuts (171) into a second surface of the body of piezoelectric material, the alignment cuts extending entirely through the body of piezoelectric material and partially into the handle layer; after forming the alignment cuts, attaching the second surface of the body of piezoelectric material to a device body; and after attaching the body of piezoelectric material to the device body, removing the handle layer from the first surface of the body of piezoelectric material.

Abstract: Microelectromechanical systems with structures having piezoelectric actuators are described. The structures each have a body that supports piezoelectric islands. The piezoelectric islands have a first surface and a second opposite surface. The piezoelectric islands can be formed, in part, by forming cuts into a thick layer of piezoelectric material, attaching the cut piezoelectric layer to a body having etched features and grinding the piezoelectric layer to a thickness that is less than the depths of the cuts. Conductive material can be formed on the piezoelectric layer to form electrodes.

Abstract: A cleaning member is pivotally fixed to a support member to clean ink-jet print heads that are positioned on a print-head receptor module. The cleaning member pivots from a cleaning position to an idle position and the print-head receptor module is pivotally fixed to a support member to allow the module to pivot from a printing position to a cleaning position. The pivotal supports are positioned such that, when the module and the cleaning member are each in their respective cleaning positions, the cleaning member is positioned to clean ink jets inserted into the receptors.
