Patent number: 9873246Abstract: 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. When the processor determines that the elapsed time is not less than the fixed time, is not less than the first time, and is less than a second time, the processor performs a second circulation operation that agitates the liquid more than the first circulation operation does. 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.Type: GrantFiled: January 26, 2017Date of Patent: January 23, 2018Assignee: BROTHER KOGYO KABUSHIKI KAISHAInventor: Yoshinori Kato
