Liquid ejecting apparatus and method for controlling liquid ejecting apparatus

摘要

A liquid ejecting apparatus includes a liquid ejecting head having a nozzle that ejects liquid and a pressure chamber in communication with the nozzle. A pressure generator causes pressure fluctuation in the liquid retained in the pressure chamber. The liquid ejecting head is capable of ejecting the liquid from the nozzle as a result of operation of the pressure generator. A driving signal generating section generates a driving signal having an ejection pulse for driving the pressure generator to eject the liquid from the nozzle. The ejection pulse is a voltage waveform four waveform portions having, respectively, voltage levels V1, V2, V3 and V4 that satisfy the following conditions (A) and (B). 0≦̸V3≦̸0.4×V2  (A) 0.2×V2≦̸V4≦̸V2  (B)
