Lorsque le produit consommable est monté sur un dispositif de formation d'image, la première unité de commande et la seconde unité de commande sont électriquement connectées au dispositif de formation d'image au moyen d'un même bus de communication. La première unité de commande est utilisée pour commander la seconde unité de commande de façon à ce qu'elle ne soit pas activée lorsqu'il est déterminé que la seconde unité de commande n'a pas besoin de communiquer avec le dispositif de formation d'image. Selon la présente invention, la consommation énergétique de la puce de produit consommable peut être réduite, ce qui permet de réduire la consommation énergétique du dispositif de formation d'image.
