ABSTRACT:
This invention provides an improved ink seal between a print cartridge body and an inkjet printhead. In a preferred embodiment, a nozzle member containing an array of orifices has a substrate, having heater elements formed thereon, affixed to a back surface of the nozzle member. Each orifice in the nozzle member is associated with a single heating element formed on the substrate. The back surface of the nozzle member extends beyond the outer edges of the substrate. Ink is supplied from an ink reservoir to the orifices by a fluid channel within a barrier layer between the nozzle member and the substrate. The fluid channel in the barrier layer may receive ink flowing around two or more outer edges of the substrate or, in another embodiment, may receive ink which flows through a hole in the center of the substrate. In either embodiment, the nozzle member is adhesively sealed with respect to the ink reservoir body by forming an ink seal circumscribing the substrate, between the back surface of the nozzle member and the body.
