摘要:
In the printer, after ink is discharged from nozzle openings by making a closed space area, formed by bringing a cap into contact with a recording head, enter into a negative pressure state due to negative pressure accumulated in a discharge flow path by driving a pump, when making the negative pressure state of the closed space area be subjected to a pressure change in a direction of coming to an atmospheric pressure state, after the air flows into the closed space area by making a second opening and closing valve provided at an inflow flow path which makes the closed space area and an aerial space communicate with each other be in an opened state, the inflow of the air into the closed space area through the inflow flow path is stopped in a state where negative pressure remains in the closed space area.
