7) Return the internal total pressure to normal. Next, the cap (4) is separated from the head (1), and the head (1) moves from the position facing the cap (4) to the printing start position. Next, operate the switching valve αΦ to transfer the ink from the ink tank (2) to the head (1).
After the ink is supplied to the head (1), the head (1) is filled with ink by fully vibrating the pressure element (9).
