ABSTRACT:
A pagewidth reading or writing bar such as a full width array ink jet printhead assembled from fully functional subunits is accurately assembled on an alignment fixture and a structural bar is aligned and bonded thereto with a thermosetting epoxy. To prevent positional disturbance of the subunits prior to curing of the epoxy, the outer subunits are anchored with a quickly curable adhesive, such as, an ultra-violet curable adhesive which, once cured, act as clamps to prevent movement of the intermediate subunits until the epoxy is subsequently cured. Since the printbars may be released from the alignment fixture with the epoxy in an uncured state, several printbars may be simultaneously cured in an oven for a more efficient fabrication process.
