Improved inkjet printhead.

摘要

A print cartridge (10) comprises a polymer tape (18) having orifices (17) formed therein and containing conductive traces (36) has a substrate (28) containing heater elements (70) affixed to a back surface of the tape. Each of the heater elements in the substrate is located substantially behind each of the orifices. The back surface of the tape is sealed with respect to an ink reservoir so that a seal (26) substantially circumscribes the substrate. The conductive traces on the tape are attached to electrodes (74) along the shorter side edges of the substrate so as not to interfere with the edge-feed of ink along the longer edges of the substrate. <IMAGE>
