Publication number: 20200101756Abstract: 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.Type: ApplicationFiled: December 2, 2019Publication date: April 2, 2020Inventors: Masato MURAYAMA, Takeshi YOSHIDA, Kaoru KOIKE, Ryoji FUJIMORI
