Résolu : voir solution (simple) au bas de ce message

Bonjour,
C'est un multicopieur Canon Pixma TS 6250. Le scanner fonctionnait, mais pas l'imprimante.
C'était un
problème de permission, qui a été réglé grâce à @xubu1957.
Seulement maintenant le scanner ne fonctionne plus.
Problème de pipe (voir plus bas), mais comment l'identifier et le résoudre?
