During printing, the bottom of the ink liquid container is opened and the ink in the container is transferred to the pair of ink rollers. The ink liquid flows into the center of the trough between the ink rollers, and the ink liquid that flows through the trough and reaches both ends of both ink rollers is forcibly returned to the ink liquid container via the return pipe by a pump to circulate the ink liquid. Just before or after the end of printing, the bottom of the ink liquid container is closed, and the pump collects the excess ink flowing through the return pipe into the ink liquid container while falling from both ends of both ink rollers. Therefore, the excess ink liquid in the return pipe can be forcibly collected into the ink container by the pump, reducing the collection time and significantly reducing the amount of ink adhering to the return pipe. Furthermore, after collecting the ink liquid, the cleaning liquid is supplied from a separately piped cleaning liquid supply pipe to the center of the valley between the ink rollers and both ends between the ink rollers, and the cleaning liquid is supplied from both ends of these ink rollers. A part of the washing liquid flowing out is circulated by the pump through the return pipe to the center of the valley between the two ink rollers, and a valve that can open and close a part of the washing liquid flowing out from both ends of the two ink rollers is provided. The ink roller and return pipe can be efficiently cleaned by discharging a portion of the liquid used for cleaning and circulating the cleaning liquid, while also draining the ink in the return pipe.
