Abstract
An ink-jet printer including: a buffer tank; an air-discharging valve device; and a valve opening-and-closing device. The ink-jet printer further includes an operating member which is arranged to be interposed between the air-discharging valve device and the valve opening-and-closing device. The valve opening-and-closing device operates the air-discharging valve device via the operating member, such that the air-discharging valve device is placed in a valve-open state and a valve-close state. The ink-jet printer is arranged to execute a first discharge operation in which the air separated from the ink in the buffer tank is discharged while placing the air-discharging valve device in the valve open state, and a second discharge operation in which an inside of the air-discharging valve device is exhausted to remove the ink remaining in the air-discharging valve device while placing the air-discharging valve device in the valve-close state.
