摘要： Described herein is a method and apparatus for driving a drop ejection device to produce drops having straight trajectories. In one embodiment, a method for driving a drop ejection device having an actuator includes building a drop of a fluid with at least one drive pulse by applying a multi-pulse waveform having the at least one drive pulse and a straightening pulse to the actuator. Next, the method includes causing the drop ejection device to eject the drop with a straight trajectory in response to the pulses of the multi-pulse waveform. The straightening pulse is designed to ensure that the drop is ejected without a drop trajectory error.

摘要： Described herein is a method and apparatus 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 multi-pulse waveform having two or more drive pulses and a cancellation pulse to the actuator. The method further includes generating a pressure response wave in a pumping chamber in response to each pulse. The method further includes causing the droplet ejection device to eject a droplet of a fluid in response to the drive pulses of the multi-pulse waveform. The method further includes canceling the pressure response waves associated with the drive pulses with the pressure response wave associated with the cancellation pulse.
