Abstract
A fluid ejection apparatus includes a fluid ejector comprising a pumping chamber, an ejection nozzle coupled to the pumping chamber, and an actuator configured to cause fluid to be ejected from the pumping chamber through the ejection nozzle. The fluid ejection apparatus includes a first compliant assembly formed in a surface of an inlet feed channel, the inlet feed channel fluidically connected to a fluid inlet of the pumping chamber; and a second compliant assembly formed in a surface of an outlet feed channel, the outlet feed channel fluidically connected to a fluid outlet of the pumping chamber. A compliance of the first compliant assembly is different from a compliance of the second compliant assembly.
