摘要： A liquid ejecting apparatus includes a liquid ejecting head with a group of nozzles. The liquid ejecting apparatus drives a pressure generating element to generate pressure variation in a liquid in a pressure generating chamber and ejects the liquid from the nozzles using the pressure variation. A driving signal generating unit generates a driving signal including an ejection driving pulse which drives the pressure generating element. An ejection control unit controls application of the ejection driving pulse to the pressure generating element to control a liquid ejecting operation of the liquid ejecting head. The driving signal generating unit generates first and second ejection driving pulses. The ejection control unit calculates a timing at which the amount of the ejected liquid becomes a predetermined correction target value in transition of the ejected liquid amount of each nozzle from a start of the ejecting operation.

摘要： A piezoelectric vibrator varies the pressure in a pressure chamber in accordance with a drive signal, whereby ink contained in the pressure chamber is ejected from a nozzle. The drive signal includes a slight-vibration pulse used to change the pressure in the pressure chamber to an extent that the ink is not ejected. The slight-vibration pulse includes a first changing component in which the potential changes from a reference potential in a negative direction in which the pressure in the pressure chamber is increased by the piezoelectric vibrator, a second changing component which is generated to follow the first changing component and in which the potential changes so as to cross the reference potential in a positive direction, and a third changing component which is generated to follow the second changing component and in which the potential changes to the reference potential in the negative direction.
