1. A liquid ejecting apparatus comprising:
a liquid ejecting head that ejects a liquid containing a humectant and water from a nozzle;
a cap configured to form a closed space to which the nozzle opens; and
a controller that controls the liquid ejecting head, wherein the controller includes:
a calculation unit that calculates an available water amount obtained by subtracting a water amount absorbed by the humectant from a water amount in the liquid, and
a discharge controller that forcibly discharges the liquid from the nozzle into the cap,
wherein the calculation unit calculates an available water amount in the cap, which is the available water amount of the liquid in the cap, based on an amount of the liquid discharged from the nozzle into the cap,
wherein when the available water amount in the cap is smaller than a preset initial available water amount, the discharge controller discharges an amount of the liquid, the amount including, as the available water amount, an amount obtained by multiplying a difference between the available water amount in the cap and the initial available water amount by a predetermined coefficient larger than one,
wherein the predetermined coefficient includes a first coefficient and a second coefficient that are set according to the available water amount in the cap,
wherein the first coefficient is set when the available water amount in the cap is less than a threshold amount,
wherein the second coefficient is set when the available water amount in the cap is larger than the threshold amount, and
wherein the first coefficient is larger than the second coefficient.
