Abstract
A damper device includes an upstream damper provided upstream of an ink head and a downstream damper provided downstream of the ink head. The upstream damper includes an upstream ink chamber communicating with an upstream inflow port and an upstream outflow port and storing ink, and an upstream detector that detects an amount of ink stored in the upstream ink chamber. The downstream damper includes a downstream ink chamber communicating with a downstream inflow port and a downstream outflow port and storing ink, and a downstream detector that detects an amount of ink stored in the downstream ink chamber.
