ABSTRACT:
A fluid ejector head includes a die with a plurality of fluid ejector units, each fluid ejector unit comprising a pumping actuator having a drive electrode, and a manifold that contacts the first side of the die to define a module volume in fluidic communication with a drainage volume. The module volume is defined in part between the manifold and at least a portion of plurality of fluid ejector units, and the drainage volume is located apart from the fluid ejector units. The module volume, in comparison to the drainage volume, has a greater ratio of interior surface area to volume or has a greater percentage of interior surface area covered by a non-wetting coating.
