Abstract
An image-forming device and method for determining use of consumable items therein includes a consumable item memory storing a substantially unique identifier designating the consumable item as one of a starter item and a normal item. A computer program retrieves the identifier from the consumable item memory and determines whether to allow formation of images using the consumable item based on whether the consumable item is a starter item or a normal item.
