1. A method of fabricating printheads each having a plurality of nozzle assemblies positioned on a substrate from a plurality of sets of the nozzle assemblies positioned on the substrate, the method comprising the steps of:

  • applying a guard defining a plurality of recesses to the substrate so that each set is located within a respective recess;

    segmenting the substrate into discrete parts;

    bonding an adhesive layer to a back side of the substrate, the adhesive layer being curable in the presence of ultraviolet light;

    segmenting the guard into discrete parts corresponding to the discrete parts of the substrate thereby forming individual printheads; and

    selectively exposing the adhesive layer to ultraviolet light allowing removal of individual printheads.
