Abstract:
According to one embodiment, an inkjet head includes a pressure chamber connected to a nozzle, an actuator corresponding to the pressure chamber and configured to change a volume of the pressure chamber, and a drive circuit configured to drive the actuator causing two or more ink droplets to be consecutively discharged from the nozzle. The drive circuit applies in sequence a first drive waveform for expanding the pressure chamber, a second drive waveform having a first pulse width, a third drive waveform for releasing the pressure chamber from an expanded state, a fourth drive waveform having a second pulse width, and a fifth drive waveform for contracting the pressure chamber.

Claim (Index 13):
An inkjet head, comprising:\n a pressure chamber connected to a nozzle; an actuator corresponding to the pressure chamber and configured to change a volume of the pressure chamber; and a drive circuit configured to drive the actuator, wherein the drive circuit applies in sequence:\n an expansion pulse for expanding the pressure chamber; \n a first contraction pulse for contracting the pressure chamber; \n a first weak contraction pulse for contracting the pressure chamber by less than the first contraction pulse contracts the pressure chamber; and \n a second contraction pulse for contracting the pressure chamber by more than the first weak contraction pulse.
