ABSTRACT:
A method of fabricating a printhead is provided. The printhead includes a substrate, a plurality of nozzles positioned on the substrate and a nozzle guard that is mounted on the substrate to cover the nozzle arrangements. The nozzle guard defines a plurality of apertures that are aligned with respective nozzles so that ink ejected from the nozzles can pass through the apertures and onto a print medium. The method includes the step of depositing a layer of a sacrificial material onto the substrate to cover the nozzles. The nozzle guard is positioned on the sacrificial material and the sacrificial material is removed.
