Abstract:
1. An assembly for mounting a printhead module in an apparatus for depositing droplets on a substrate, the printhead module having a surface including orifices from which the droplets are ejected, the assembly comprising: a frame having an opening defined in a surface of the frame, the opening permitting the surface of the printhead module that is to be mounted on the frame to be exposed for depositing the droplets on the substrate, the surface of the frame extending in a plane parallel to the to-be-exposed surface of the printhead module; a spring element adapted to spring load the printhead module against an edge of the opening in the frame when the printhead module is mounted in the assembly, the spring element being located in the opening; and an alignment datum formed on an edge of the opening on a side opposite of the spring element for positioning the printhead module at a specific position with respect to the frame along an axis, the alignment datum and spring element being fixed relative to the frame, not operable to move the module, and in contact with the printhead module when the printhead module is mounted in the assembly.
