ABSTRACT:
An ink jet printhead cartridge having a fluid valved breather. The ink jet printhead cartridge includes a housing having an air inlet, an ink outlet, a first chamber, and a second chamber. The first chamber contains a supply of ink and is substantially free of ink-retaining foam. The second chamber includes an ink-retaining foam which saturates with ink for supply to an ink jet printhead. An air transfer passageway connects the first chamber to the second chamber so that air pressure affects the level of ink in the first chamber thereby maintaining a level of ink in the second chamber sufficient for supplying ink to the ink jet printhead.
