ABSTRACT:
A printhead for a continuous ink jet printer has a body with a circular recess in an end face thereof. A circular piezoelectric transducer is disposed in the recess so as to provide a short ink chamber adjacent the face of the body and the piezoelectric transducer is arranged to expand and contract in the direction of its axis when an excitation voltage is applied to it. An ink feed channel connects with the recess for feeding ink to the ink chamber and a nozzle plate is detachably mounted on the end face of the body to eject ink under pressure when the piezoelectric transducer is actuated.
