Abstract: An inkjet printer has a valve unit in a moisture supply path that connects a moisture tank and the fluid nozzles of a moisture discharge head. The moisture discharge head has an operating lever for opening and closing the valve unit, and when the cap approaches the moisture discharge head to seal the fluid nozzle faces of the moisture discharge head, a wiper unit that moves with the cap depresses the operating lever and opens the valve unit. Because the valve unit is open while the fluid nozzle faces are sealed by the cap, moisture leakage and backflow are suppressed.
