Abstract:
1. A printing device comprising: a head configured and arranged to discharge sedimentary ink; a first reservoir unit configured and arranged store the sedimentary ink; a second reservoir unit configured and arranged to store the sedimentary ink from the first reservoir unit; a first flow path for which one end is connected to the head, and the other end is connected to the first reservoir unit; a second flow path for which one end is connected to the first flow path, and the other end is connected to the second reservoir unit; a third flow path for which one end is connected to the second reservoir unit, and the other end is connected to the second flow path; a first pressure supply unit provided on the second flow path, and configured and arranged to send the sedimentary ink in a direction for which the sedimentary ink is moved from the first reservoir unit to the second reservoir unit; a second pressure supply unit provided on the third flow path, and configured and arranged to send the sedimentary ink in a direction for which the sedimentary ink is moved from the second reservoir unit to the first reservoir unit; and a control unit configured to execute a stirring process of stirring the sedimentary ink by returning the sedimentary ink inside the second reservoir unit to the first reservoir unit using the second pressure supply unit after the sedimentary ink inside the first reservoir unit is moved to the second reservoir unit using the first pressure supply unit.
