ABSTRACT:
A nozzle chamber structure of a printhead is positioned on the substrate to define a nozzle chamber in fluid communication with an ink supply channel and an ink ejection port in fluid communication with the nozzle chamber. A micro-electromechanical ink ejection mechanism that is positioned on the substrate operatively with respect to the nozzle chamber to eject ink from the ink ejection port includes an elongate actuator arm that is fixed at one end to the substrate and has an ink ejection member positioned on an opposite end and in a respective nozzle chamber. The actuator arm of the nozzle arrangement is oriented at an acute angle with respect to a print medium feed direction.
