Claim 9:
10. A method of fluid ejection, the method comprising:
flowing fluid along a feed channel and into each of multiple pumping chambers, in which an actuator is disposed adjacent to each of the pumping chambers; and
operating one or more of the actuators to cause fluid to be ejected from the corresponding pumping chamber and through a corresponding nozzle fluidically connected to the pumping chamber,
in which operating each actuator causes deflection of a meniscus of fluid in a dummy nozzle defining an opening in a wall of the feed channel,
in which the dummy nozzle and the nozzles are defined in a substrate, an interior surface of the substrate forming the wall of the feed channel,
in which the dummy nozzle defines a first opening in the wall of the feed channel and a second opening in an exterior surface of the substrate, wherein the first opening is larger than the second opening, and
in which the nozzles are arranged along a line, and in which the feed channel is laterally offset from the line.
