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.
