摘要：
A method of authenticating a consumable used in an imaging device includes the steps of providing the consumable with a memory; monitoring usage of the consumable; determining whether the consumable has reached a usage threshold; and, if the consumable has reached the usage threshold, then performing the further steps of: renewing the consumable; generating an authentication code signifying the renewing of the consumable; and storing the authentication code in the memory.
