A control method of a liquid ejecting apparatus is provided. The liquid ejecting apparatus includes a liquid ejecting head for ejecting a liquid in an inner-space thereof through a nozzle, an inflow-channel for flowing the liquid into the inner space, an outflow-channel for flowing the liquid out of the inner space, and a valve for the inflow-channel. The control method includes first control of opening the inflow-channel by opening the valve in accordance with a negative pressure on a downstream side of the valve to generate a liquid flow from the inflow-channel to the outflow-channel, second control of opening the inflow-channel by opening the valve by an external force to generate the liquid flow from the inflow-channel to the outflow-channel, and performing the second control, in accordance with a flow amount of the liquid flow, to open the valve under the first control.
