Abstract
A fluid ejection apparatus includes a plurality of fluid ejectors. Each fluid ejector includes a pumping chamber, and an actuator configured to cause fluid to be ejected from the pumping chamber. The fluid ejection apparatus includes a feed channel fluidically connected to each pumping chamber; and at least one compliant structure formed in a surface of the feed channel. The at least one compliant structure has a lower compliance than the surface of the feed channel.
Claims10
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.

- 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.
