A microchannel fluidic device, such as an ink jet printhead, includes an fluid reservoir for receiving ink or other fluid from a supply. The reservoir has an inlet in communication with the supply, and an outlet. A plurality of nozzles are in fluid communication with the reservoir for delivering ink or fluid from the reservoir. The outlet of the reservoir is constructed and arranged such that air bubbles in the reservoir are ejected by differential pressure between the inlet and outlet, rather than being forced through nozzles. An overflow reservoir captures fluid ejected from the outlet during priming operations thereby to reduce waste, to enable treatment of the fluid, and/or to recirculate the fluid.
