Abstract
An apparatus is provided that uses a consumable item, of given type, requiring occasional renewal. The apparatus has a first operating mode in which it only works with a subset of consumable items of the given type; the apparatus also has a second operating mode in which it is not restricted to working with consumable items of the aforesaid subset. The apparatus is changed from its first mode to its second mode following a determination that the apparatus has reached a predetermined time or usage threshold for being in its first mode. The change to the second mode is preferably effected in response to a release code generated either by the apparatus itself or by a remote system following the determination that the predetermined time or usage threshold being reached. Advantageously, the consumable items can be used to pass usage data to a remote system.
