Abstract: When a processor of a print device determines that an elapsed time since a circulation operation of a liquid is not less than a fixed time and does not determine that the elapsed time is not less than a first time, the processor performs a first circulation operation that circulates the liquid in a state in which a supply flow path and a circulation flow path are not open to the atmosphere.

Therefore, the print device is able to agitate the liquid in accordance with the time that has elapsed since the circulation operation was last performed.
