  • Patent number: 10532578
    Abstract: A printing apparatus (200) includes a slot (230) to and from which a memory unit (100) storing permitted usage amount information can be attached and removed, and a processing unit (210) that carries out a process for updating estimated ink amount information. The processing unit (210) carries out a charging process using a first memory unit (100-1), and in the case where a second memory unit (100-2) has been attached to the slot (230) after the charging process, the processing unit (210) does not carry out a charging process using the second memory unit (100-2) until a consumed ink amount expressed by the estimated ink amount information exceeds a prescribed threshold (WTH). The processing unit (210) carries out the charging process using the second memory unit (100-2) in the case where the consumed ink amount has exceeded the prescribed threshold (WTH).

  • Patent number: 10525499
    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.

  • Patent number: 10464332
    Abstract: 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 that is information for estimating an amount of the ink in an ink holding unit. When the memory unit is attached to the slot, the processing unit carries out a charging process that updates the estimated ink amount information using the permitted usage amount information in the memory unit, on the basis of a process for determining whether or not consumed ink amount expressed by the estimated ink amount information exceeds a prescribed threshold (WTH). The processing unit executes forced charging process that executes the charging process in the case where there is an instruction from an operator of the printing apparatus before the prescribed threshold WTH is exceeded.

  • Publication number: 20190111697
    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.

  • Patent number: 9090079
    Abstract: A printing apparatus includes first to n-th (n is an integer equal to or greater than 2) ink tanks in which ink accommodated in an ink pack is filled, first to n-th slots that correspond to the ink tanks, first to n-th memory units that are packaged together with the ink pack and are respectively installed in the slots, and a processing unit. The processing unit outputs a read-out command in which communication ID information is set, to the storage device included in the memory unit that is installed in the selected slot, determines whether ink color information that is read out and an ink color corresponding to the slot are consistent with each other, and determines that the memory unit is erroneously installed when the read-out ink color information and the ink color corresponding to the slot are inconsistent with each other.
