PROBLEM TO BE SOLVED: To efficiently remove foreign matters adhering to outer peripheral surfaces of rollers by using humidification air that is supplied to a discharge space to suppress thickening of liquid within a discharge port.SOLUTION: A controller supplies humidification air to a discharge space V1 while maintaining a closed state of a cap 44 and then, brings the cap 44 into an open state. Until a predetermined time passes after the cap 44 is brought into the open state, driving of fans 62x, 62y is maintained. Due to this, air is sucked via an opening 61xa so that the humidification air supplied to the discharge space V1 moves toward a pair of rollers 24. Then, paper is carried via the pair of rollers 24. |
