ABSTRACT:
The contiguous inlets of components of a thermal ink jet printhead are sealed by applying a sealant to provide a substantial but not complete seal around the edge of an inlet of the printhead die mounted on a heater plate to provide an edge free of sealant and by injecting a liquid encapsulant to seal the contiguous inlets of the die and a manifold at the edge free of sealant.
