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.

Abstract: A liquid ejecting apparatus includes a liquid ejecting head having nozzles for ejecting a liquid, and an attachment section to which a maintenance unit to be used for maintenance of the liquid ejecting head is to be detachably attached. If the maintenance unit having a maintenance mechanism for performing the maintenance by driving force transmitted from the attachment section is a first unit and the maintenance unit having no maintenance mechanism is a second unit, one of a plurality of the maintenance units including the first unit and the second unit and having different structure is interchangeably attached to the attachment section, and the attachment section includes an identification section configured to identify the structure of the attached maintenance unit and a driving-force transmission section configured to transmit the driving force to the attached first unit.
