ABSTRACT:
A page-wide, drop-on-demand type ink jet printhead and an associated method of manufacturing an orifice plate. The orifice plate is comprised of a block of material in which a first portion of the block of material has been removed to define an ink reservoir. Also formed in the orifice plate are a series of apertures, each of the apertures includes an ink jet and an ink jet nozzle. A fill channel, which extends between the ink reservoir and each ink jet, is also formed in the orifice plate to provide a supply of ink to the ink jet. An intermediate layer is mounted to the orifice plate. The intermediate layer is formed of an active piezoelectric material and a series of piezoelectric actuators, each acoustically coupled to a corresponding one of the series of apertures, are formed on the intermediate layer. By applying a voltage differential between first and second electrodes, which make up each piezoelectric actuator, the intermediate layer is deflected to effect ejection of a droplet of ink from the aperture acoustically coupled to each piezoelectric actuator.
