Abstract: PROBLEM TO BE SOLVED: To stably supply a liquid to each common channel for the liquid (ink), and to smoothly remove bubbles included in the liquid in each common channel.
SOLUTION: An ink manifold 83 is connected to a supply port 22 of a first buffer tank 21. To a supply port 32 of a second (N=2) buffer tank 31, the ink manifold 83 and also a discharge port 23 of the first (N-1th) buffer tank 21 are connected via an opening and closing valve 86. When the ink is ejected by a head chip 60 and a head chip 70, a pump 71 is driven to transfer the ink in a state with the opening and closing valve 86 being opened. When the bubbles in the ink of the buffer tank 21 and the buffer tank 31 are removed, the pump 11 is driven to transfer the ink in a state with the opening and closing valve 86 being closed.
