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 16):
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 comprises:\n a first waveform setting unit configured to set a first drive waveform unit for causing one ink droplet to be discharged from the nozzle; \n a second waveform setting unit configured to set a second drive waveform unit for causing two or more ink droplets to be consecutively discharged from the nozzle; \n a drive waveform generating unit configured to generate a drive waveform signal by selecting and connecting the first and second waveform units; and \n a waveform selecting unit configured to select the drive waveform signal to be applied to the actuator based on a printing data.
