ABSTRACT:
A bubble jet print cartridge assembly includes an ink supply housing having an ink reservoir and a fluid block component capping the ink reservoir and having ink passages extending from the reservoir to an ink outlet(s). A drop ejection chip comprising a substrate having resistive heater elements and electrode leads is attached to the outer side of the fluid block component with a peripheral chip edge(s) adjacent the ink outlet(s). A raised ink barrier fence formed on the outer surfaces of the fluid block and chip surrounds the heater elements and ink outlet(s). The fence has a height extending above the top surface of the supported chip and an orifice plate member is affixed at its periphery to the top of the barrier fence so as to enclose the region surrounded by said barrier fence.
