Abstract

L'invention concerne une came rotative dans une imprimante multimédia qui est utilisée pour positionner une commande d'une tête d'impression et/ou d'une barre d'effacement à l'intérieur de l'imprimante, permettant à la came rotative d'élever et d'abaisser la tête d'impression, la barre d'effacement ou une combinaison de celles-ci pour accepter des épaisseurs différentes de papiers réinscriptibles à l'intérieur de l'imprimante, et pour entrer en contact ou empêcher tout contact avec un papier réinscriptible dans le but de prolonger la durée de service de la tête d'impression, de la barre d'effacement ou d'une combinaison de celles-ci. La came rotative peut être couplée à un moteur de commande qui peut être utilisé pour entraîner la came rotative dans une seule position ou dans une pluralité de positions de papier prédéfinie(s), chaque position de papier prédéfinie étant utilisée pour régler et positionner correctement la tête d'impression, la barre d'effacement ou une combinaison de celles-ci.
