Abstract: A printer has a recording head, a relay container from which ink is supplied to the recording head, and to which the ink is supplied from a terminal container, a pressurizing pump and a depressurizing pump for supplying the ink from the terminal container to the relay container, and a control unit. The control unit calculates an estimated consumption amount of the relay container based on the amount of the ink supplied from the relay container to the recording head, and consumed and the amount of the ink supplied from the terminal container to the relay container, and calculates the amount of the ink supplied from the terminal container to the relay container using the minimum value of tolerance of a supply amount of the depressurizing pump.

Abstract: Provided is a technique that can reduce at least one of various inconveniences in a sub-tank, such as stock management being complicated. The sub-tank includes: a consumable article containing portion; a sub-tank-side storage unit; and a case that can be detachably attached to multiple slots in a consumable article consumption apparatus and contains the consumable article containing portion. In a state before the sub-tank is first mounted in the slot, the sub-tank-side storage unit stores a sub-tank-side identifier configured to distinguish from another sub-tank, and in a state after the sub-tank is first mounted in the slot, the sub-tank-side storage unit further stores sub-tank-side consumable article information relating to an attribute of the consumable article replenished in a consumable article containing portion.

Abstract: A liquid droplet ejecting apparatus includes a liquid droplet ejecting head that includes a plurality of nozzles from which a liquid supplied from a liquid supply source through a liquid supply path is ejected as a liquid droplet, and ejects the liquid droplet from the nozzle to a recording medium to perform a recording process, a first detecting section that detects a vibration waveform of the pressure chamber, which is vibrated when an actuator is driven to cause the pressure chamber communicating with the nozzle to vibrate, to detect a state inside the pressure chamber, and a second detecting section that reads a pattern formed on the recording medium by ejecting the liquid droplet from the nozzle to detect an ejection state of the liquid droplet.

Abstract: The control unit, when a first condition in which a minimum value of a suppliable time that is a time it takes for an amount of liquid contained in each supply-side sub tank to reach an amount corresponding to a switching preparation time necessary for switching between the refill-side sub tank and the supply-side sub tank is less than or equal to a maximum value of a full refill refilling time that is a period from when refill processing for performing refilling of the liquid from the main tank is started in each of the plurality of refill-side sub tanks until a state is achieved in which the refill-side sub tank is fully re-filled with liquid and can supply the liquid is satisfied, the refill processing is performed on the plurality of refill-side sub tanks.
