An inkjet cartridge lid including serpentine trenches and orifices formed within a top surface. At least one of the serpentine trenches intersects with at least one of the orifices. The venting structure includes a corridor interposing at least two separate ink reservoirs and including opposing first and second ends. The first end of the corridor resides in communication with an external environment while the second end is partitioned to establish a separate passage in communication with each of the at least two separate ink reservoirs, each passage including a hollow extending into an interior of the ink reservoir.
