METHOD OF MANUFACTURE OF AN INK JETPRINTHEAD HAVING A MOVING NOZZLE WITH AN EXTERNALLY ARRANGED ACTUATOR

摘要

A method of manufacture of an ink jet printhead includes the steps of providing a substrate ( 16 ). An array of nozzle assemblies ( 10 ) is created on the substrate with a nozzle chamber ( 34 ) in communication with a nozzle opening ( 24 ) of a nozzle ( 22 ) of each nozzle assembly ( 24 ). The nozzle ( 22 ) of each assembly ( 10 ) is displaceable relative to the substrate ( 16 ) for effecting ink ejection on demand and the nozzle assembly ( 1 ) includes an actuator unit ( 28 ) connected to the nozzle ( 22 ) and arranged externally of the chamber ( 34 ) for controlling displacement of the nozzle ( 22 ).
