Liquid ejecting apparatus and method for determining liquid depletion to maintain a pressure differential between an ink jet head and ink cartridge
A liquid-ejecting apparatus includes a liquid-ejecting section that ejects a liquid onto an object, a liquid container containing the liquid and detachably attached to the liquid-ejecting section, and a depletion-determining section. The liquid container supplies a predetermined amount of liquid to the liquid-ejecting section by a pressure corresponding to the amount of ink remaining in the liquid container. The depletion-determining section determines depletion of the liquid if the amount of ink remaining falls below a threshold depending on temperature.
