摘要：
A liquid ejection apparatus includes a pressure sensor and a determining unit. The pressure sensor is configured to detect a pressure in an ink supply path for use in supplying ink from an ink tank to a recording head. The determining unit determines whether the ink supply path is anomalous based on a result of detection of the pressure in the ink supply path by the pressure sensor performed in response to application of a fluctuating pressure to the ink in the ink tank.
