ABSTRACT:
A first code is programmed into a memory of an image-formation device consumable item, outside of an image-formation device. Upon insertion of the image-formation device consumable item into the image-formation device, it is detected that the memory of the consumable item has programmed therein the first code. The image-formation device determines whether the first code is identical to a second code programmed into a memory of the image-formation device. Where the first code is identical to the second code, the consumable item is allowed to be used by the image-formation device to form images on media.
