Abstract
A mount portion mounts a container containing liquid. A fluid passages connects the mount portion to a head portion provided to inject liquid. A reservoir portion reserves liquid and is provided on the fluid passage. An open-close valve is provided on a connection path which is a part of the fluid passage and connects the mount portion to the reservoir portion. The control unit controls opening and closing of the open-close valves such that a first valve open time period for the open-close valve provided on a first connection path is shorter than a second valve open time period for the open-close valve provided on a second connection path. The pressure of the liquid that flows in the reservoir portion from the first connection path is higher than the pressure of the liquid that flows in the reservoir portion from the second connection path.
