Abstract
Ink is supplied to a supply tank from a second buffer tank, and ink is pressure-fed from the supply tank to a head. Further, ink is supplied from the second buffer tank to a recovery tank, and ink is pressure-fed from the recovery tank to the head. In both pressure-feedings, ink containing air bubbles within the head is recovered at a first buffer tank. The ink, that contains the air bubbles and is recovered at the first buffer tank, is sent to the second buffer tank via an ink flow path. A degassing section is provided on the ink flow path, and a degassing process is carried out while ink is being fed.
