    Abstract: A method for ejecting fluid from a fluid ejector includes actuating a piezoelectric actuator to cause deformation of a membrane defining a wall at a first end of an elongated channel of the fluid ejector, the deformation of the membrane causing ejection of a droplet of fluid from a nozzle disposed at a second end of the channel. The elongated channel fluidically connects a first channel to the nozzle, the first channel disposed at the first end of the elongated channel, and wherein an impedance of the first channel is at least ten times greater than an impedance of the elongated channel. Deformation of the membrane induces fluid flow along the elongated channel, and wherein at least 60% of the fluid flow induced by the deformation of the membrane is in a direction extending from the first end of the elongated channel to the second end of the elongated channel.

    Abstract: An apparatus includes a reservoir and a printhead. The printhead includes a support structure including a deformable portion defining at least a top surface of a pumping chamber, a flow path extending from the reservoir to the pumping chamber to transfer fluid from the reservoir to the pumping chamber, and an actuator disposed on the deformable portion of the support structure. A trench is defined in a top surface of the actuator. Application of a voltage to the actuator causes the actuator to deform along the trench, thereby causing deformation of the deformable portion of the support structure to eject a drop of fluid from the pumping chamber.

    Abstract: A system includes a print head including multiple nozzles formed in a bottom surface of the print head. The nozzles are configured to eject a liquid onto a substrate. The system includes a gas flow module configured to provide a flow of gas through a gap between the bottom surface of the print head and the substrate. The gas flow module can include one or more gas nozzles configured to inject gas into the gap. The gas flow module can be configured to apply a suction to the gap.
