ABSTRACT:
A nozzle arrangement for an inkjet printhead comprises a substrate defining an ink supply channel; a nozzle chamber structure mounted on the substrate, the nozzle chamber structure defining a nozzle chamber in fluid communication with the ink supply channel and a nozzle rim defining an ink ejection port in fluid communication with the nozzle chamber, the nozzle chamber structure further defining a slot in a first side wall thereof; a post, provided outside of the nozzle chamber, extending from the substrate; and a thermal actuator mechanism including an actuator arm extending from the post and through the slot to terminate freely in the nozzle chamber. The actuator arm comprises a slot protection barrier extending substantially orthogonally therefrom, the slot protection barrier positioned adjacent to the first side wall and spaced therefrom to define an ink holding area between the slot protection barrier and the first side wall.
