摘要： A method is described wherein one or more parameters are measured that affect the nozzle velocity at which a printing fluid is ejected from a pumping chamber through a nozzle. The printing fluid is contained in the pumping chamber actuated by deflection of a piezoelectric layer. A surface area of an electrode actuating the piezoelectric layer is reduced based at least in part on the measured one or more parameters. Reducing the surface area of the electrode reduces the actuated area of the piezoelectric layer.

摘要： A method for cleaning a nozzle plate includes applying a first solution to a surface of the nozzle plate, and applying a second solution different from the first solution to the surface of nozzle plate to remove the first solution from the surface of nozzle plate. The first solution wets the nozzle plate and is a solvent to dried ink deposited on the surface of the nozzle plate. The surface of the nozzle plate is non-wetting to the second solution.

摘要： A method for causing fluid to be ejected from a fluid chamber of a jet in a printhead. An actuator is actuated with a first energy imparting pulse to push fluid away from the actuator and toward a nozzle. Following a lapse of a first interval, the actuator is actuated with second energy imparting pulse to push fluid away from the actuator and toward the nozzle. Following a lapse of a second interval as measured from the second energy imparting pulse, the actuator is actuated with a break-off pulse to cause fluid extending out of an orifice of the nozzle to break off from fluid within the nozzle, wherein the second lapse is longer than the first lapse and is an inverse of the meniscus-jet mass frequency.

摘要： A MEMS based device is described with recesses covered by a membrane. The membranes over the recesses are highly uniform due to being formed by a stack of layers that are epitaxial layers with high uniformity. The unnecessary layers of the stack, such as the handle layer, are removed prior to completion of the device to achieve a membrane with a desired thickness.

摘要： 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.

摘要： Described herein is a method, apparatus, and system for driving a droplet ejection device with multi-pulse waveforms. In one embodiment, a method for driving a droplet ejection device having an actuator includes applying a first subset of a multi-pulse waveform to the actuator to cause the droplet ejection device to eject a first droplet of a fluid in response to the first subset. The method includes applying a second subset of the multi-pulse waveform to the actuator to cause the droplet ejection device to eject a second droplet of the fluid in response to the second subset. The first subset includes a drive pulse that is positioned in time near a beginning of a clock cycle of the first subset. The first droplet has a smaller volume than the second droplet.

摘要： Microelectromechanical systems with structures having piezoelectric actuators are described. The structures each have a body that supports piezoelectric islands. The piezoelectric islands have a first surface and a second opposite surface. The piezoelectric islands can be formed, in part, by forming cuts into a thick layer of piezoelectric material, attaching the cut piezoelectric layer to a body having etched features and grinding the piezoelectric layer to a thickness that is less than the depths of the cuts. Conductive material can be formed on the piezoelectric layer to form electrodes.
