Abstract: A printer includes ink heads, an ink head conveyor, a movable table, cap valves, lifters, a guide device, and a controller. The conveyor moves the ink heads in a main scanning direction. The movable table includes caps and is movable in the main scanning direction by the conveyor. The guide device defines a path along which the movable table is movable between a cap attaching position, a valve opening position, and a retracted position. Movement of the movable table to the valve opening position causes the lifters to abut against the cap valves to bring the cap valves to an open state and expose opening/closing passages to the atmosphere. Movement of the movable table to the cap attaching position from the valve opening position causes the lifters to move away from the cap valves to bring the cap valves to a closed state.
