Abstract:
1. A liquid-discharging device comprising: a nozzle configured and arranged to discharge liquid including a substance having sedimentation properties; a liquid supply channel configured and arranged to supply the liquid to the nozzle from a liquid tank that stores the liquid; an inspection part configured and arranged to bring the liquid to be discharged from the nozzle to a first electric potential by a first electrode, to discharge the liquid toward a second electrode of a second electric potential which is different from the first electric potential, and to inspect a discharge state of the liquid based on a change of an electrostatic capacitance between the first electrode and the second electrode; a stirring part configured and arranged to stair the liquid in a predetermined area of the liquid supply channel; and a control part configured and arranged to cause the nozzle to eject the liquid in order to substitute the liquid in an area downstream side than the predetermined area with respect to a liquid supply direction with the liquid stirred by the stirring part in the predetermined area, the control part being configured to determine a timing of ejection completion of the liquid based on the change of the electrostatic capacitance detected by the inspection part.
