Pb de numérisation à partir d'une multifonction Epson ET-2750

MaxJ01 · Le 02/02/2020, à 20:21

Bonjour,
J'utilise Ubuntu depuis plusieurs années. J'ai un pb d'installation de la fonction scanner de ma multifonction Epson ET-2750. L'imprimante fonctionne très bien sans le pilote Epson.
Distirbution Ubuntu 19.10

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).

Merci par avance pour votre réponse.

Bonjour tout le monde, j'ai oublié les information sir libsane :

Merci

Ton scanner n'est pas encore supporté par sane .
C' est pour cela que scanimage -L ne le voit pas, c est pour cela que simple-scan ne peut pas l ouvrir non plus.
les pilotes installé sont les bon.
Tu dois passer par l utilitaire d'Epson

imagescan

cela devrait marcher.

MaxJ01 · Le 04/02/2020, à 09:13

OK merci pour ta réponse. J'ai lu beaucoup de fil sur ce forum où il est expliqué que ça devrait fonctionner.
En particulier le fil que ta as eu avec matt, apparemment ça a fonctionné chez lui avec le même modèle de multifonction.
Cependant comme je cherche à scanner, je peux utiliser n'importe quelle application donc pourquoi pas imagescan.
Quand je lance imagescan, installé par les utilitaires Epson

imagescan
Gtk-Message: 09:03:44.773: Failed to load module "canberra-gtk-module"

je n'ai aucune détection de scanner.
L'erreur signalée au lancement sur le module "canberra" serait à ignorer.

MaxJ01 · Le 04/02/2020, à 09:18

Oups je continue d'utiliser imagescan !
mais le résultat avec simple-scan "Aucun périphérique de numérisation n'a été détecté" reste KO.
Par avance merci

sylvain3800 · Le 04/02/2020, à 21:51

Bon imagescane fonctionne , c'est un bon début
on va essayer de faire fonctionner simple-scan
donne stp le retour de ces commandes :

cat /lib/udev/rules.d/60-libsane.rules | grep EPSON

ls /lib/udev/rules.d

sudo find / -name "*epkowa*"

sudo adduser max saned

sudo adduser saned scanner

ensuite redémarre ton ordi pour que cela soit pris en compte puis

scanimage -L

sudo scanimage -L

@++

MaxJ01 · Le 05/02/2020, à 09:53

Ok merci pour ces informations mais je ne peux pas scanner, aucune application fonctionne, ni imagescan, ni simple-scan ni xsane.
J'ai toujours un message signifiant qu'aucun scanner n'est détecté.

C'est très curieux car j'ai déjà passé cette commande.

sudo adduser saned scanner
L'utilisateur « saned » appartient déjà au groupe « scanner ».

A suivre après le reboot.

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).

Je suis bien connecté en USB 2 (pas sur un connecteur USB bleu).
C'est très curieux que cela ne fonctionne toujours pas.
Par avance merci pour tes conseils.
