  • Patent number: 10466624
    Abstract: A toner cartridge includes a screw configured to send stirred toner to an outlet through which the toner is discharged. The toner cartridge includes a partition between the screw and a toner stirrer. The toner stirrer at a default position is in contact with a top of the partition and covers the screw from above to define a closed space around the screw. The closed space is separate from a remaining space having the toner therein. The closed space is in communication with the remaining space when the toner stirrer rotates from the default position to be away from the toner transport screw, enabling the toner to move toward the toner transport screw.

  • Patent number: 9152967
    Abstract: When a device desired to acquire emission right information is selected on a selection screen displayed on a display unit and a “SEND” icon is manipulated, a control unit causes the display unit to display consumables information of consumables granted with emission rights and consumables not granted with emission rights that is received from a server. When a user selects a consumable item that is desired to be ordered from among consumables indicated by the consumables information displayed on the display unit, and manipulates a “SEND ORDER SHEET” icon on the ordering screen, the control unit sends an order sheet to the server. The control unit causes the display unit to display, in the case of receiving order sheet receipt notification from the server in response to the sent order sheet, the received order sheet receipt notification.
