Print device and non-transitory computer readable medium

A print device comprising:

• a head provided with a nozzle configured to discharge a liquid;
• a storage portion configured to store the liquid;
• a supply flow path connected to the head and the storage portion and configured to supply the liquid to the head from the storage portion;
• a circulation flow path, one end of the circulation flow path being connected to one of the storage portion and the supply flow path at a first connection portion, the other end of the circulation flow path being connected to one of the head and the supply flow path at a second connection portion, the position of the second connection portion in the supply flow path being closer to the head than is the position of the first connection portion in the supply flow path;
• a circulation portion configured to circulate the liquid through the supply flow path and the circulation flow path;
• a processor;
• and
• a memory storing computer readable instructions that, when executed by the processor, perform processes including
• first acquisition processing that acquires an elapsed time since a circulation operation was last performed,
• second acquisition processing that acquires an operation time for the circulation portion in accordance with the elapsed time that was acquired by the first acquisition processing, and
• operation processing that operates the circulation portion in a sealed state for the operation time that was acquired by the second acquisition processing, the sealed state being a state in which the supply flow path and the circulation flow path are not open to the atmosphere.

A non-transitory computer readable medium storing computer readable instructions that, when executed by a processor of a print device provided with:

• a head provided with a nozzle configured to discharge a liquid,
• a storage portion configured to store the liquid,
• a supply flow path connected to the head and the storage portion and configured to supply the liquid to the head from the storage portion,
• a circulation flow path, one end of the circulation flow path being connected to one of the storage portion and the supply flow path at a first connection portion, the other end of the circulation flow path being connected to one of the head and the supply flow path at a second connection portion, the position of the second connection portion in the supply flow path being closer to the head than is the position of the first connection portion in the supply flow path,
• a circulation portion configured to circulate the liquid through the supply flow path and the circulation flow path, and
• the processor configured to control the circulation portion,
• perform processes including
• first determination processing that determines whether a first time has elapsed since a circulation operation was last performed,
• first circulation processing that circulates the liquid by a first circulation operation in a sealed state when the first determination processing has determined that the first time has not elapsed, the sealed state being a state in which the supply flow path and the circulation flow path are not open to the atmosphere, and
• second circulation processing that agitates the liquid by a second circulation operation in the sealed state when the first determination processing has determined that the first time has elapsed, the second circulation operation agitating the liquid more than does the first circulation operation.
