Abstract
In a printhead assembly, an ink jet printhead is fixed to the wall of an ink supply manifold. The printhead has an ink inlet in communication with a plurality of nozzles, and the manifold contains liquid ink which flows to the printhead inlet through an outlet in the manifold wall. A preformed hot melt adhesive member with a slot therein is positioned between the manifold wall and the printhead with the slot of the adhesive member surrounding the manifold outlet and printhead inlet, so that when the adhesive member is heated and cooled a hermetic seal is formed.
