Abstract
A liquid-discharging device includes a nozzle that discharges liquid including a substance having sedimentation properties, a liquid supply channel, an inspection part, stirring part and a control part. The inspection part brings the liquid to be discharged from the nozzle to a first electric potential by a first electrode, discharges the liquid toward a second electrode of a second electric potential, and inspects a discharge state of the liquid based on a change of an electrostatic capacitance between the first electrode and the second electrode. The control part causes the nozzle to eject the liquid in order to substitute the liquid in an area downstream side than a predetermined area with the liquid stirred by the stirring part in the predetermined area. The control part determines a timing of ejection completion of the liquid based on the change of the electrostatic capacitance.
