Claim 9:
10. A method for controlling a liquid ejecting apparatus, the liquid ejecting apparatus including a liquid ejecting head that performs recording by ejecting liquid onto a medium, a supply flow passage that is in communication with the liquid ejecting head, a first supply flow passage for communication between a first liquid container and the supply flow passage, the first liquid container containing liquid, a second supply flow passage for communication between a second liquid container and the supply flow passage, the second liquid container containing a same kind of liquid as the liquid contained in the first liquid container, a switching unit configured to switch a flow passage that is in communication with the supply flow passage, between the first supply flow passage and the second supply flow passage, and a movement restriction unit configured to, linked with switching by the switching unit, restrict movement of the first liquid container and the second liquid container selectively,
the method comprising:
when instructions for operation involving liquid consumption are received, bringing either the first supply flow passage or the second supply flow passage into communication with the supply flow passage by the switching unit, and restricting the movement of the liquid container that is currently in communication with the supply flow passage by the movement restriction unit;
performing the operation involving liquid consumption; and
after the operation is performed, performing switching to a state in which neither of the first supply flow passage and the second supply flow passage is in communication with the supply flow passage by the switching unit, and performing restriction cancellation such that neither of the movement of the first liquid container and the movement of the second liquid container is restricted by the movement restriction unit.
