Abstract
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.
