Using a consumable component with an apparatus

摘要

A consumable component designed to be usable with an apparatus has a surface that includes a non-reflective area forming a predefined pattern in a reflective material. Electromagnetic energy reflected from the surface and read by the apparatus contains a predefined characteristic. The apparatus is programmed not to consume the consumable component if the reflected electromagnetic energy does not contain the predefined characteristic. A system that includes the consumable component and a reader is disclosed. So are methods of using a system and of designing a label and providing it on a consumable component.
