Patent ID: 7712863

Claim:
A maintenance method for a liquid ejecting apparatus that ejects liquid from a nozzle of a liquid ejecting head to a liquid receiver and that, when a predetermined amount of the liquid collects in the liquid receiver, discharges the predetermined amount of the liquid, the maintenance method comprising: in a state in which a nozzle opening face of the liquid ejecting head is disposed facing the liquid receiver in a non-contact manner, applying an electric field between the nozzle opening face and the liquid receiver; ejecting the liquid from the nozzle to the liquid receiver; detecting a voltage change based on electrostatic induction occurring when the liquid is ejected to the liquid receiver; determining the height of the level of the liquid collected in the liquid receiver on the basis of a result of detection of the voltage change; and when the level of the liquid reaches a predetermined height, discharging the liquid collected in the liquid receiver.
