Abstract

L'invention se rapporte à une pluralité de systèmes d'alimentation en encre destinés à un système d'impression par jet d'encre existant. Ces systèmes d'alimentation en encre comportent des réservoirs d'encre, de formes et tailles différentes, susceptibles de s'adapter à une pluralité de niveaux d'encre restante. Chaque système d'alimentation en encre comporte également un connecteur électrique et un dispositif de mémorisation des informations s'adaptant aux divers niveaux de l'encre restante. Ce dispositif de mémorisation des informations peut être un circuit de mémoire fournissant des informations de validation au système d'impression.
