Abstract:
A liquid ejecting apparatus includes a liquid ejecting head and a driving signal generating device. The liquid ejecting head includes a pressure generating device and a pressure chamber in communication with a nozzle opening. The pressure generating device generates pressure fluctuation in liquid in the pressure chamber. The liquid ejecting head discharges the liquid from the nozzle opening in the form of a liquid droplet. The driving signal generating device generates a driving signal that includes a discharge pulse for discharging the liquid droplet during every discharge period. The driving signal generating device sets, into the discharge pulse, an expansion element for expanding the pressure chamber, a discharge element for discharging the liquid droplet by contracting the pressure chamber, and a vibration damping element for suppressing residual vibration, which occurs in the pressure chamber after the liquid droplet is discharged, by further contracting the pressure chamber.
