Inkjet printhead nozzle assembly having a raised rim to support an ink meniscus
Abstract:
Provided is a nozzle assembly for an inkjet printhead. The nozzle assembly includes a substrate defining a nozzle chamber and an ink inlet channel leading to the chamber. The nozzle assembly also includes a nozzle defined on the substrate and located over the nozzle chamber, the nozzle having a crown portion with a skirt portion depending from the crown portion, the skirt portion forming a first part of a peripheral wall portion of the nozzle chamber, the nozzle surrounded by a raised rim which supports a meniscus of a body of ink in the nozzle chamber. Also included is an actuator with a connecting arm fast with the nozzle to operatively displace the nozzle towards the substrate, wherein the nozzle, actuator and connecting arm are defined according to micro-electromechanical systems (MEMS) techniques.
