ABSTRACT:
When a process unit of the image forming apparatus has reached the end of its service life, the apparatus prints recovery information on a sheet, such as an officially approved "postage paid" mark, a recipient's name, the recipient's address and the recipient's postal code. The printed information tells the user that the service life of the process unit has expired, that the unit is a consumable component to be recovered for recycling, and that the unit is to be returned to the designated address.
