Abstract
A liquid circulating apparatus includes a circulation route configured to circulate liquid through a liquid ejecting head, the circulation route including: a supply-side tank leading to a supply port of the liquid ejecting head; and a discharge-side tank leading to a discharge port of the liquid ejecting head, wherein the liquid is circulated by setting pressure in the supply-side tank higher than pressure in the discharge-side tank, and a sum of the pressure in the supply-side tank and the pressure in the discharge-side tank is set smaller when initial filling for filling the circulation route with the liquid is performed than when the liquid is circulated.
