    Abstract: A bottle for ink supply is shipped with a two-dimensional code attached to the bottle, individual information being embedded in the two-dimensional code. A user reads the two-dimensional code with a portable information terminal and thereby transmits the individual information to a management server. If there is no fraud or problem, the management server transmits a passcode to the portable information terminal. When the bottle is placed in a bottle storing unit, the two-dimensional code is read by a two-dimensional code reader, and a passcode is created based on the individual information embedded in the two-dimensional code. Only when the passcode matches the passcode registered by the user, ink in the bottle becomes ready to use.

A main body stores the recording material to be used in an image recordation process on a recording sheet by the image recording apparatus. A storage stores residual amount information indicating a current residual amount of the recording material. An interface receives consumption amount information. A reduction counter circuit subtracts a consumption amount based on the consumption amount information from the current residual amount to acquire the updated residual amount, and updates the residual amount information in the storage so that the residual amount information indicates the updated residual amount in a case where the consumption amount is larger than zero. The reduction counter maintains the residual amount information in the storage so that the residual amount information keeps on indicating the current residual amount in a case where the consumption amount is smaller than or equal to zero.

  • Patent number: 10336065
    Abstract: An inkjet recording apparatus includes: a tank; a recording head; a display; an operation interface; a memory; and a controller. The controller performs: an inquiry process in which a displaying and receiving process is repeatedly performed for each of ink chambers of the tank to inquire whether ink has been injected into a target ink chamber; an operation determination process to determine whether all of operations received in the inquiry process are first operations; and, in response to the determination in the operation determination process that all of the operations received in the inquiry process are first operations, a confirmation process to prompt a user to input a third operation to confirm that ink has been injected into all of the ink chambers. The controller initializes, in response to receipt of the third operation in the confirmation process, count values for all of the ink chambers.
