Abstract:
In accordance with an embodiment, an inkjet head comprises a pressure chamber, an actuator, a nozzle plate, and a head drive circuit. The pressure chamber accommodates ink. The actuator is arranged in correspondence with the pressure chamber. The nozzle plate has a nozzle communicating with the pressure chamber. The head drive circuit applies a drive pulse signal, which includes a first pulse for returning a volume of the pressure chamber after expansion, a second pulse for returning the volume of the pressure chamber after contraction, and a third pulse for returning the volume of the pressure chamber after contraction, to the actuator in such a manner that the second pulse is applied without providing a standby time before the first pulse, and the third pulse is applied without providing the standby time after the first pulse.

Claim (Index 20):
