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.

Abstract: A fluid ejector includes a nozzle layer, a body, an actuator and a membrane. The body includes a pumping chamber, a return channel, and a first passage fluidically connecting the pumping chamber to an entrance of the nozzle. A second passage fluidically connects the entrance of the nozzle to the return channel. The actuator is configured to cause fluid to flow out of the pumping chamber such that actuation of the actuator causes fluid to be ejected from the nozzle. The membrane is formed across and partially blocks at least one of the first passage, the second passage or the entrance of the nozzle. The membrane has at least one hole therethrough such that in operation of the fluid ejector fluid flows through the at least one hole in the membrane.

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 piezoelectric device and method of manufacturing the same and an inkjet head are described. In one embodiment, the inkjet print head comprises a plurality of jets, wherein each of the plurality of jets comprises a nozzle, a pressure chamber connected with the nozzle, a piezoelectric body coupled to the pressure chamber, and an electrode coupled to the piezoelectric body to cause displacement of the piezoelectric body to apply pressure to the pressure chamber in response to a voltage applied to the electrode; and wherein electrodes of two or more of the plurality of jets have different sizes to cause their associated piezoelectric bodies to have a uniform displacement amount when the voltage is applied to the electrodes.

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.

Abstract: Methods and systems are described herein for driving droplet ejection devices with multi-level waveforms. In one embodiment, a method for driving droplet ejection devices includes applying a multi-level waveform to the droplet ejection devices. The multi-level waveform includes a first section having at least one compensating edge and a second section having at least one drive pulse. The compensating edge has a compensating effect on systematic variation in droplet velocity or droplet mass across the droplet ejection devices. In another embodiment, the compensating edge has a compensating effect on cross-talk between the droplet ejection devices.
