Abstract
The field of the invention is an improved keying system for categorizing a consumable cartridge by using a two component system including a relatively long-lived portion and the relatively short-lived consumable cartridge. The improved system includes a lug element and a structure for mounting the lug element to the relatively long-lived portion, which may be the inner housing of a copier machine or other machine using consumable cartridges. Ideally, the lug element is self-fixturing into a void space. The consumable cartridge has portions defining a void into which the lug element projects when the consumable cartridge is inserted into the relatively long-lived portion for machine operations.
