Abstract: A consumable resource option control unit includes a consumable resource and an option key coupled to the consumable resource. The option key is configured to enable an optional mode of operation for an image-forming device and to cause a display associated with an image-forming device to indicate availability of the mode of operation.

Abstract: An image-printing device includes a connection bay that accepts an insertable consumable resource. The consumable resource includes an option key that identifies at least one mode of operation associated with the consumable resource. The connection bay outputs at least one signal associated with the mode of operation when the consumable resource is inserted. A controller receives the signal associated with the mode of operation and in response outputs display information suitable for use by a display to indicate a selectable availability of the at least one mode of operation.
