13. A maintenance method of a liquid ejecting apparatus which includes
a liquid ejecting portion configured to eject a first liquid from an opening of a nozzle disposed in a nozzle forming surface; - and
a fluid ejecting apparatus configured to eject at least one of a gas and a second liquid toward the nozzle forming surface in a state where a space including the nozzle forming surface is covered with air, the fluid ejecting apparatus including a fluid ejecting nozzle configured to move in a moving direction along the nozzle forming surface at an ejecting position facing the nozzle forming surface of the liquid ejecting portion, the fluid ejecting nozzle at the ejecting position being disposed lower than the nozzle of the liquid ejecting portion in a gravity direction, and the fluid ejecting nozzle having a liquid ejecting opening through which the second liquid is ejected and a gas ejecting opening through which the gas is ejected, a liquid accommodating portion configured to accommodate the second liquid, a liquid flow path through which the second liquid accommodated in the liquid accommodating portion flow toward the liquid ejecting opening, and a gas flow path through which the gas flow toward the gas ejecting opening, the maintenance method comprising; generating a mixed fluid in which the second liquid of droplet-like shape and the gas are mixed by ejecting the gas from the gas electing opening in a flowable state where the second liquid in the liquid accommodating portion is flowable into the liquid flow path; and ejecting the second liquid from the fluid ejecting nozzle by pumping the second liquid in the liquid flow path toward the liquid ejecting opening, wherein a pressure applied to the second liquid in the liquid flow path when ejecting the second liquid is higher than a pressure applied to the second liquid in the liquid flow path when generating the mixed fluid. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24)
