Abstract
An inkjet printhead with an array of nozzles 10 formed on a supporting substrate 16. Each nozzle has a chamber 34 for holding ink, each nozzle chamber being partially defined by a nozzle portion that defines a nozzle opening 24. The nozzle 22 of each assembly 10 is displaceable relative to the substrate 16 for effecting ink ejection on demand. The nozzles 10 each have a respective actuator unit 28 connected to the nozzle 22 and arranged externally of the chamber 34 for controlling displacement of the nozzle 22.
Claims6
An inkjet printhead comprising:
- a supporting substrate for mounting in a printer;
- an array of nozzle chambers for holding ink, each nozzle chamber being partially defined by a nozzle portion that defines a nozzle opening, the nozzle portion being displaceable relative to the substrate to eject ink from the chamber through the nozzle opening;
- an actuator unit corresponding to each of the nozzle chambers respectively, each of the actuator units being secured to the substrate adjacent the nozzle chambers;
- and,
- an arm connecting each of the actuator units to the nozzle portion of their respective nozzle chambers such that the nozzle portion is cantilevered over the supporting substrate by the actuator unit.
