Abstract
A printer to which an ink tank that contains an ink is fixed and that is configured such that a user can refill the ink tank with the ink includes: a consumption amount calculation unit that calculates a consumption amount of the ink; a storage unit that stores a count value that is updated based on the consumption amount of the ink calculated by the consumption amount calculation unit; a sensor that detect whether or not the ink is present at a predetermined position in the ink tank; and a control unit that executes ink presence/absence detection with the sensor. The ink presence/absence detection is for determining whether or not the ink is present. The control unit resets the count value to an initial value thereof if the control unit executes the ink presence/absence detection and determines that the ink is present.
