Patent ID: 8764142

Claim:
A control method of a liquid ejection apparatus, wherein the liquid ejection apparatus comprises: a liquid ejection head comprising a pressure generating unit configured to generate a pressure variation to liquid inside a pressure chamber communicating with a nozzle, and further configured to eject liquid from the nozzle according to driving of the pressure generating unit; and a drive signal generating unit configured to repeatedly generate a drive signal according to a timing signal that is generated based on movement of the liquid ejection head, wherein the drive signal includes an ejection drive pulse ejecting liquid from the nozzle and a fine vibration drive pulse finely vibrating a meniscus at the nozzle to a degree that the liquid is not ejected from the nozzle, the method comprising: from the drive signal generating unit, outputting a first unit signal including a set of one or more of the ejection drive pulses and the fine vibration drive pulse and a second unit signal including a set of one or more of the ejection drive pulses and having a generation period that is shorter than that of the first unit signal; outputting, from the drive signal generating unit according to one timing signal at a steady speed area of the liquid ejection head, a third signal, the third signal comprising both the first unit signal and the second unit signal; outputting, from the drive signal generating unit according to one timing signal at an acceleration or deceleration area of the liquid ejection head, a fourth signal, wherein the fourth signal comprises the first unit signal, and wherein the fourth signal is different than the third signal.
