Patent ID: 8403440

Claim:
A drop-emitting apparatus, comprising: a drop generator; a drop generating waveform applied to the drop generator during a firing interval if a drop is to be emitted, the drop generating waveform comprising a pulse having a first polarity followed by a pulse having a second polarity followed by a third pulse of either the first or second polarity and magnitude of fifty percent or less than the pulse of the first polarity; and a non-drop generating waveform applied to the drop generator during the non-firing interval if a drop is not to be emitted, the non-drop generating waveform comprising a single pulse having the second polarity, the single pulse having a duration in a same range of the third pulse, wherein the third pulse and the single pulse each have four segments, the single pulse having a first negative going segment, a second negative going segment, a substantially constant level segment, and a positive going segment.
