ABSTRACT:
A printhead has a substrate with a mounting surface for a printhead die. The printhead die includes a first face bonded to the mounting surface of the substrate and a second face opposite the first face. The second face including at least one array of marking elements disposed along a marking element array direction. An edge of the printhead die is substantially parallel to the marking element array direction. An inclined surface is positioned proximate to, but not overlapping the edge of the printhead die, wherein a distance from the inclined surface to the mounting surface of the substrate at a first location is greater than a distance from the inclined surface to the mounting surface of the substrate at a second location, the first location also being nearer the edge of the printhead die that is substantially parallel to the marking element array direction than the second location.
