Abstract
A liquid ejecting apparatus includes a liquid ejecting unit that ejects liquid, and a plurality of pumps each supplying the liquid toward the liquid ejecting unit by repeating a sucking state and a discharging state. When one of the pumps is in the discharging state and a storage amount of the liquid stored in the pump chamber of the one pump becomes equal to a threshold, another of the pumps is switched to the discharging state. A value obtained by adding an inflow of the liquid flowed into the pump chamber of the other pump to an ejection amount of the liquid ejected from the liquid ejecting unit is defined as a discharge amount of the liquid discharged from the pump chamber of the one pump during a period of the discharging state.
