发明名称 Liquid ejecting apparatus
摘要 Provided is a liquid ejecting apparatus which includes a plurality of liquid receiving portions in which the same kinds of liquid are received, a switching unit which switches the liquid receiving portion that supplies the liquid to a liquid ejecting head, and a controller which performs a maintenance process including discharging the liquid through the liquid ejecting head, in which, when a liquid residual amount of the liquid receiving portion that supplies the liquid to the ejecting head, which is calculated by a residual amount estimation portion, is less than a determination value, the controller performs the maintenance process in a state where the liquid receiving portion to supply the liquid to the liquid ejecting head is selected among the plurality of liquid receiving portions and the liquid is supplied from the selected liquid receiving portion to the liquid ejecting head.

主权项 1. A liquid ejecting apparatus which includes a liquid ejecting head ejecting liquid, the liquid being supplied from a plurality of liquid receiving portions in which the same kinds of the liquid are received through a confluent flow path, the liquid ejecting apparatus comprising: a switching unit which switches the liquid receiving portion communicated with the confluent flow path so as to supply the liquid to the liquid ejecting head; a residual amount estimation portion which separately estimates liquid residual amounts of the respective liquid receiving portions by integrating liquid consumption amounts by the liquid ejecting head; and a controller which performs a maintenance process including discharging the liquid through the liquid ejecting head, wherein, in a case where, among the liquid receiving portions, the liquid receiving portion which supplies the liquid to the liquid ejecting head is set to one liquid receiving portion, when a liquid residual amount of the one liquid receiving portion, which is calculated by the residual amount estimation portion, is less than a determination value, the controller performs the maintenance process in a state where the liquid receiving portion communicated with the confluent flow path is selected among the plurality of liquid receiving portions and the liquid is supplied from the selected liquid receiving portion to the liquid ejecting head.
