Claim 0:
1. 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 the one or more actuators causes fluid to flow from the corresponding pumping chambers to the corresponding nozzles via respective descenders,
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 nozzles are arranged along a line, and in which the feed channel is laterally offset from the line.
