Abstract
Official abstract text for this publication.
It is possible to generate an ejection driving pulse which ejects ink, and a plurality of minute vibration driving pulses which cause a pressure fluctuation in ink in a pressurizing chamber to an extent of not causing the ink to be ejected; the ejection driving pulse includes a first expansion element which causes the pressurizing chamber to be expanded by being changed from a reference potential to a first potential which is lower than the reference potential, and a first contraction element which causes the pressurizing chamber to be contracted by being changed from the first potential to the reference potential; and the minute vibration driving pulse includes a second contraction element which causes the pressurizing chamber to be contracted by being changed from a second potential which is lower than the reference potential to a third potential which is higher than the second potential and the first potential, and is lower than the reference potential, and a second expansion element which causes the pressurizing chamber to be expanded by being changed from the third potential to the second potential.
First claim
Opening claim text (preview).
What is claimed is: 1. A liquid ejecting apparatus comprising: a liquid ejecting head which causes a pressure fluctuation in liquid in a pressurizing chamber by driving a pressure generator, and ejects the liquid from a nozzle which communicates with the pressurizing chamber using the pressure fluctuation, wherein it is possible to generate a first driving waveform in which liquid is ejected from the nozzle by driving the pressure generator, and a plurality of second driving wav…
