Abstract: A binary array ink jet printhead assembly includes a cavity for containing ink, nozzle orifices in fluid communication with the cavity for passing the ink from the cavity to form droplets, the nozzle orifices extending along a length of the cavity, and an electrode assembly. The electrode assembly includes a front face configured to be disposed generally parallel to a plurality of droplet paths of droplets from the nozzle orifices. A plurality of charge electrodes are disposed on the front face, each charge electrode corresponding to a droplet path and disposed parallel to the droplet path. Circuitry is disposed on the electrode assembly, wherein each electrode is electrically connected to the circuitry. The circuitry is further in electrical connection to a connector for connecting the electrode assembly to a controller for the printhead.

Abstract: A droplet generator for a continuous stream ink jet printhead includes an elongate cavity for containing ink and nozzle orifices in fluid communication with the cavity for passing the ink from the cavity to form jets. The nozzle orifices extend along a length of the cavity. A mounting plate provides a wall of the cavity opposite the nozzle orifices. A plurality of actuators is disposed in the cavity to vibrate the ink in the cavity such that each jet breaks up into ink droplets at substantially a same predetermined distance from the wall. Each of the plurality of actuators is integrally connected to the mounting plate by a membrane.
