Abstract
This apparatus includes an external tank in which ink is stored outside a circulation path, a branch pipe connecting a branch point on the circulation path and the external tank, an external pump that delivers ink from the external tank to the circulation path, a switch valve, and a temperature sensor that detects a temperature of ink in the circulation path. The switch valve can switch between a state in which the external tank communicates with the branch point via the external pump and the branch pipe and a state in which the external tank communicates with the branch point not via the external pump, but via the bypass pipe. When a result of detection by the temperature sensor is out of a predetermined range, a control unit can deliver ink in the circulation path to the external tank via the bypass pipe.
