Abstract:
A printhead (10) for use in an inkjet printing process includes a substrate (12) having at least one ink feed opening (14) defined therein, an ink chamber (16) in operative and fluid communication with the ink feed opening(s) (14), and a nozzle plate (18) disposed on a portion (P1) of the substrate (12). The nozzle plate (18) has a plurality of orifices (20) defined therein. The printhead (10) further includes a firing resistor (22) disposed on another portion (P2) of the substrate (12) and proximate to the ink feed opening(s) (14) and a barrier structure (24) disposed on the other portion (P2) of the substrate (12) and positioned adjacent to the firing resistor (22).
