Consumable unit and image forming apparatus including memory storing consumable item information
摘要：
A consumable unit and an image forming apparatus for controlling a consumable includes a first memory that stores consumable item information regarding the consumable and provides the consumable item information through password authentication, and a second memory that rewrites recycling prevention information, which indicates that recycling is impossible, a limited number of times. Therefore, if the consumable is replaced, it is possible to prevent the first memory and second memory from being recycled.
