Title:
液体噴射装置、及び液体噴射装置の制御方法
Document Type and Number:
Japanese Patent JP4321563
Kind Code:
B2
Abstract:
A liquid ejecting apparatus includes a liquid ejecting head with a pressure chamber communicating with a nozzle opening and a pressure generator capable of causing a pressure fluctuation to liquid in the pressure chamber. The liquid ejecting head discharges liquid droplets by operating the pressure generator. The drive signal generator generates a drive signal including a drive pulse which includes a first expanding element that expands the pressure chamber, a first discharging element that contracts the pressure chamber expanded by the first expanding element in order to discharge a liquid droplet, a second expanding element that expands the pressure chamber, and a second contracting element that contracts the pressure chamber. The time from the beginning of the first discharging element to the end of the second contracting element is set to ½ to 1 of the natural vibration period of the liquid in the pressure chamber.
