Pb imprimante Canon avec Simple scan

[temperdu]

Bonjour, sous Mint 18.3, j'ai installé scangearmp2 et mon imprimante/scanner Canon TS6051 est reconnue. Je parviens à scanner mais c'est très rudimentaire : juste des JPG et des PDF d'un page, sans crop possible. La partie imprimante fonctionne. Tout est relié en USB pour un début.

J'aurais souhaité utiliser Simple Scan ou XSane mais ça ne marche pas : aucun des deux logiciels ne trouve le scanner. Pour tant...

Code : Tout sélectionner

$ sudo sane-find-scanner

  # sane-find-scanner will now attempt to detect your scanner. If the
  # result is different from what you expected, first make sure your
  # scanner is powered up and properly connected to your computer.

  # No SCSI scanners found. If you expected something different, make sure that
  # you have loaded a kernel SCSI driver for your SCSI adapter.

mais toutefois ...
