Abstract
A damper and an ink circulation method capable of suppressing deposition of color materials of ink are provided. A damper is a hydraulic head difference type damper for supplying ink supplied from an ink tank of an inkjet printer by a hydraulic head difference, into a head. The damper has a supply chamber for temporarily storing ink, an ink chamber connected to the supply chamber through a connection passage and configured to supply the ink into the head, and an on-off valve. The on-off valve opens the connection passage if the ink contained in the ink chamber decreases, and blocks the connection passage if the ink contained in the ink chamber increases. A guide port for guiding the ink contained in the ink chamber to a circulation tube for circulating the ink between the ink chamber and the ink tank is formed in the ink chamber.
