The upper limit mark is arranged so that in a first case where an entire amount of liquid stored in a refilling container is injected into a storage portion when a notification unit notifies of a first state, a liquid level of the liquid in the storage portion is located between an inlet port and the upper limit mark, and in a second case where the entire amount of liquid stored in the refilling container is injected into the storage portion when the notification unit notifies of a second state, the liquid level overlaps with the upper limit mark.

Liquid ejecting apparatus and ordering system

A printing apparatus includes a liquid accommodation body into which liquid contained in a liquid container is configured to be poured, a printing section that performs printing by discharge of liquid supplied from the liquid accommodation body, a counting section that performs counting relating to an amount of consumption of liquid with which a liquid container was contained and counting relating to an amount of consumption of liquid per predetermined period of time, and a delivery request section that, based on a counting result yielded by the counting section, sends the server apparatus a delivery request for a liquid container by a time that is earlier by a delivery period of a liquid container than an estimated timing of completion of consumption of liquid with which a liquid container was contained.

Printing apparatus and printing system

A control unit of a liquid consumption apparatus performs determination processing that determines whether or not each of a first housing container and a second housing container is an unsuitable container that does not satisfy a use condition, performs switching decision that decides switching of a supply source that supplies a liquid composition to a liquid consumption unit to the second housing container when the first housing container is determined to be the unsuitable container while the liquid composition is being supplied from the first housing container to the liquid consumption unit, and continues supply of the liquid composition from the first housing container to the liquid consumption unit regardless of whether or not the second housing container is the unsuitable container until when the switching decision is performed while the liquid composition is being supplied from the first housing container to the liquid consumption unit.

Liquid consumption apparatus and control method of liquid consumption apparatus

A consumables consumption apparatus includes a cartridge determination section that determines one of a specified cartridge and an unspecified cartridge which is attached to the consumables consumption apparatus in accordance with maintenance subject information indicating a subject of a maintenance contract and a notification section that requests a selection of one of use agreement of the unspecified cartridge and replacement of the unspecified cartridge by the specified cartridge when the cartridge determination section determines that the unspecified cartridge is attached and that makes a notification indicating at least one of information on cancellation of the maintenance contract and information on replacement by the specified cartridge when the use agreement is selected.

Consumables consumption apparatus and consumables consumption system

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.

Sub-tank and consumable article consumption system

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.

Recording apparatus

A printing apparatus () includes a slot () to and from which a memory unit () storing permitted usage amount information can be attached and removed, and a processing unit () that carries out a process for updating estimated ink amount information. The processing unit () carries out a charging process using a first memory unit (-), and in the case where a second memory unit (-) has been attached to the slot () after the charging process, the processing unit () does not carry out a charging process using the second memory unit (-) until a consumed ink amount expressed by the estimated ink amount information exceeds a prescribed threshold (WTH). The processing unit () carries out the charging process using the second memory unit (-) in the case where the consumed ink amount has exceeded the prescribed threshold (WTH).
