ABSTRACT:
A nozzle arrangement for an inkjet printer includes a wafer substrate defining a supply channel; side and roof walls positioned on the substrate, said walls defining a nozzle chamber operatively supplied with ink via the supply channel, and a nozzle rim defined in the roof wall; an actuator device passing through a slot in a side wall of the chamber, the device configured to operatively eject ink from the nozzle rim; and an actuator slot protection barrier mounted on the actuator device, and extending at a normal to the actuator device, the actuator slot protection barrier located proximate the slot and configured to reduce ink wicking on the nozzle rim during ejection of ink from the nozzle rim.
