Abstract: A liquid ejecting apparatus includes a liquid ejecting section from which liquid is ejected. A return passage has a first end connected to a supply passage at a first location and a second end connected to the supply passage at a second location. The second location is positioned closer to the liquid ejecting section than the first location. The return passage and the supply passage constitute a circulating passage. A pump can cause fluid to flow through the circulating passage. A replaceable filter unit is a portion of the return passage. A discharge passage through which the fluid is discharged to the outside is connected to the return passage. An inflow controller can suppress external fluid from entering the discharge passage.

Abstract: A printer 100 has a recording head 22, a relay container 30 from which ink is supplied to the recording head 22, and to which the ink is supplied from a terminal container 60, a pressurizing pump 34 and a depressurizing pump 35 for supplying the ink from the terminal container 60 to the relay container 30, and a control unit 10. The control unit 10 calculates an estimated consumption amount of the relay container 30 based on the amount of the ink supplied from the relay container 30 to the recording head 22, and consumed and the amount of the ink supplied from the terminal container 60 to the relay container 30, and calculates the amount of the ink supplied from the terminal container 60 to the relay container 30 using the minimum value of tolerance of a supply amount of the depressurizing pump 35.
