摘要:
A unit installable in an apparatus and a method of managing a unit installed in an apparatus are provided. The unit includes a container for a consumable, and a chip mounted to the container. The chip includes a first memory to store data that is accessible and decodable by the apparatus to authenticate the unit. The chip includes a second memory to store recycling prevention 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.

摘要:
An image forming apparatus having a photosensitive element, is provided with a light source for scanning light to the photosensitive element; a light blocking member disposed in a light traveling path of the light from the light source and moving between a blocking position where the light blocking member blocks the light scanned from the light source and a withdrawal position where the light blocking member is withdrawn from the blocking position; a power supply unit for supplying electric power to the light source for scanning light; a power switch unit for regulating power supply from the power supply unit; and an operating part locating the light blocking member at the blocking position and controlling the power switch unit to cut off the power supply in a predetermined exposure condition. As a result, a user is kept from being exposed to the light from a light source.
