14. A liquid amount determination method for a liquid consumption apparatus in which a liquid container that houses liquid is mountable, the method comprising:
-
determining whether the state of the liquid consumption apparatus is a first state in which a liquid-consuming operation by the liquid consumption apparatus is underway or a second state in which a liquid-consuming operation by the liquid consumption apparatus has been completed; and determining whether the amount of liquid housed in the liquid container is equal to or less than a prescribed amount via a first determination process when the liquid consumption apparatus is determined to be in the first state and via a second determination process that is different from the first determination process when the liquid consumption apparatus is determined to be in a second state.
