    • 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.
    • 流体喷射头包括具有多个流体喷射器单元的模具,每个流体喷射器单元包括具有驱动电极的泵送致动器和与模具的第一侧接触的歧管,以限定与排水流体连通的模块体积 卷。 模块体积部分地限定在歧管和多个流体喷射器单元的至少一部分之间,并且排出体积与流体喷射器单元分开。 与排水体积相比,模块体积具有更大的内表面积与体积的比例,或者具有由非润湿涂层覆盖的较大比例的内表面积。
