Abstract:
1. A printhead comprising a plurality of nozzle assemblies, each nozzle assembly comprising: a substrate; an inkjet nozzle disposed on said substrate, said inkjet nozzle having an actuator for ejecting an ink droplet from said inkjet nozzle when a resistive element of said actuator is heated by an electrical current; a drive transistor for providing an energy pulse to said resistive element of said actuator; and control logic for controlling said drive transistor, wherein nozzles are spaced from other nozzles ejecting ink of a same color by less than 25 μm in a direction transverse to the direction of movement of a print media upon which ink is ejected, and wherein the resistive element of said actuator is spaced apart from said substrate.
