ABSTRACT:
A unit cell is provided for an inkjet printhead. The unit cell includes a multilayered substrate defining an ink inlet passage. Walls extend from the substrate. A nozzle plate is supported by the walls to define a nozzle chamber in fluid communication with the ink inlet passage. The nozzle plate further includes a nozzle rim bounding an aperture in fluid communication with the nozzle chamber. A looped and elongate heater element is suspended within the nozzle chamber which, when heated, causes ink in the nozzle chamber to be output through the aperture.
