Abstract: A liquid ejecting apparatus includes a liquid ejecting head that ejects a plurality of kinds of photocurable type liquids, an irradiation unit that irradiates light that cures the liquids, a liquid receiving portion that is capable of receiving the liquids that are ejected from the liquid ejecting head, and a control unit that controls the ejection of the liquids from the liquid ejecting head. Among the plurality of kinds of liquids that are ejected, the control unit ejects a liquid that is cured with most ease when the light is irradiated before at least one different liquid other than the liquid in a case in which the plurality of kinds of liquids are ejected into the liquid receiving portion from the liquid ejecting head.

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 heating portions for heating liquid, a liquid ejecting head for ejecting the liquid heated by the heating portions, and a maintenance device for performing maintenance of the liquid ejecting head by causing the liquid to be discharged from the liquid ejecting head through sucking operation. The maintenance device performs a first suction for cleaning the liquid ejecting head by causing the head to discharge the liquid, waits until liquid is heated by the heating portions, and then performs a second suction with a suction force weaker than that of the first suction.
