Patent attributes
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 sacrificial material on the substrate having the nozzles positioned thereon so that a first portion of the sacrificial material encases the nozzles, positioning the nozzle guard on the substrate so as to contact a second portion of the sacrificial material not encasing the nozzles, and subsequently removing the first portion of the sacrificial material.
