ABSTRACT:
A printhead for an inkjet printer employs an ink fill slot having an extended portion disposed as a depression on the primary surface of the printhead substrate. The barrier layer of the printhead forms the walls of the ink ejection chambers, the walls of and constrictions in the ink fill channels, and the contoured barrier lobes between the ink fill channels. The extended portion of the ink fill slot follows the contour of the barrier lobes such that the length of the substrate shelf between the ink fill channel constriction and the extended portion of the ink fill slot is equalized between ink ejection chambers.
