Abstract

The present invention relates to a liquid ejecting apparatus capable of preventing cross talk even when a liquid is ejected simultaneously from a plurality of nozzles adjacent to each other in the same nozzle group and to a method of controlling the liquid ejecting apparatus. The ejection driving pulse DP is a voltage waveform including a preliminary expansion section p1, an expansion hold section p2, a contraction section p3. The contraction section p3 includes a first contraction component p3a in which the potential is varied in the minus direction from the expansion potential VH, an intermediate hold component p3b in which an intermediate potential VM1, which is the termination potential of the first contraction component p3a, holds for a given time, and a second contraction component p3c in which the potential is varied in the minus direction from the intermediate potential. The hold time of the intermediate hold component is greater than 0 and 0.12 Tc or less. The potential of the intermediate hold component is in the range from 50% to 60% of the potential of the hold section.

Description

technical field [0001] The present invention relates to a liquid ejecting device such as an inkjet printer and a control method thereof, particularly a liquid ejecting device capable of controlling ejection of liquid by applying an ejection drive pulse to a pressure generating unit and a control method thereof. Background technique [0002] A liquid ejecting device is a device that includes a liquid ejecting head having a nozzle for ejecting a liquid, and ejects various liquids from the liquid ejecting head. As the representative of this liquid ejecting device, for example, can enumerate: have the ink-jet type recording head (hereinafter referred to simply as recording head) as liquid ejecting head, by injecting liquid ink from the nozzle of this recording head to recording paper etc. An image recording device such as an inkjet printer (hereinafter referred to as a printer) that forms dots after spraying and attaching a recording medium (attachment object) to record an image...
