ABSTRACT:
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).
