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.
