Abstract
A liquid ejecting apparatus includes a head, a first holder to which a main tank is attached, a second holder to which a sub tank is attached, a supply channel coupled to the head and the first holder, a branch channel that branches off at an intermediate point in the supply channel and that is coupled to the second holder, and a controller. Each of the main tank and the sub tank is a liquid container including a container and a memory circuit. The first holder includes a connector. The controller updates, via the connector, remaining amount information stored in the memory circuit of the main tank, performs an operational control based on the remaining amount information stored in the memory circuit of the main tank, and does not perform the operational control based on the remaining amount information stored in the memory circuit of the sub tank.
