摘要:
This disclosure describes a headland design for adhesively attaching a printhead to a print cartridge which reduces dimple in the nozzle member and the attendant nozzle trajectory errors. 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 ink ejection chamber and heating element formed on the substrate. 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 headland area of the print cartridge. This method and design for a print cartridge headland which provides a seal directly between a nozzle member and an ink reservoir body. The above design provides reduced yield losses, and thus lower manufacturing costs, when manufacturing print cartridges.
