Probleme dectection scanner canon MB5150

Bonjour à tous,
Pour commencer, je suis débutant sur ubuntu!
J'ai acheté mon imprimante canon MB5150 multifonction et j'ai bien galéré pour la faire imprimer mais bon ça marche, maintenant le scanner n'est pas détecte par simplescan ou par xsane ! j'en suis a 3 heures de recherche et de copié/collé sur le terminal pour rien.
j'ai besoin d'aide
