发明名称 LIQUID EJECTING APPARATUS AND METHOD CONTROLLING LIQUID EJECTING APPARATUS
摘要 A liquid ejecting apparatus includes: a liquid ejecting head which includes nozzles, pressure generating chambers communicating with the nozzles, and pressure generating elements causing a pressure change in a liquid of the pressure generating chambers and which ejects the liquid from the nozzles in response to an operation of the pressure generating elements; and a driving signal generating unit which drives the pressure generating elements to repeatedly generate a driving signal containing an ejection driving pulse used to eject the liquid from the nozzles. The ejection driving pulse has a pulse waveform containing a first pressure generating chamber expansion component which expands the pressure generating chamber to draw a meniscus toward the pressure generating chamber side, a pressure generating chamber contraction component which contracts the pressure generating chamber expanded by the first pressure generating chamber expansion component to push the meniscus toward the liquid ejection side, and a second pressure generating chamber expansion component which expands the pressure generating chamber contracted by the pressure generating chamber contraction component to draw the meniscus toward the pressure generating chamber side again. Each of the pressure generating chamber expansion components has a plurality of different potential change ratios.
