Liquid-discharging device, liquid stirring method, and liquid filling method

摘要

A liquid ejection device includes a head section, a first liquid reservoir section, a supply passage, a second liquid reservoir section, an outgoing passage that sends liquid from the first liquid reservoir section to the second liquid reservoir section and includes a shared passage shared with the supply passage, a return passage that sends the liquid from the second liquid reservoir section to the first liquid reservoir section, and a controller. After the controller performs a stirring process of stirring the liquid by causing the liquid in the first liquid reservoir section to pass through the outgoing passage and subsequently causing the liquid in the second liquid reservoir section to pass through the return passage, the controller performs a process of flowing out a part of the liquid in the first liquid reservoir section toward the shared passage.

主权项

1. A liquid-discharging device comprising:
a head section configured and arranged to discharge liquid onto a medium; a first liquid reservoir section configured and arranged to store the liquid; a supply passage configured and arranged to supply the liquid from the first liquid reservoir section to the head section; a second liquid reservoir section configured and arranged to store the liquid sent out from the first liquid reservoir section and to send the liquid back to the first liquid reservoir section; an outgoing passage through which the liquid passes when the liquid is sent from the first liquid reservoir section to the second liquid reservoir section, the outgoing passage including a shared passage that is shared with the supply passage; a return passage through which the liquid passes when the liquid is sent from the second liquid reservoir section to the first liquid reservoir section; and a controller configured to perform a stirring process of stirring the liquid by causing the liquid in the first liquid reservoir section to pass through the outgoing passage so as to be sent toward the second liquid reservoir section and subsequently causing the liquid in the second liquid reservoir section, which has been sent from the first liquid reservoir section, to pass through the return passage, and return to and enter the first liquid reservoir section, the controller being configured to perform a process of flowing out a part of the liquid in the first liquid reservoir section, which has been sent from the first liquid reservoir section to the second liquid reservoir section and returned to the first liquid reservoir section, toward the shared passage after performing the stirring process.
