Alors tout d'abord la piste de nouvo09 :
Imprimante éteinte:

Donc aucune différence...
Un petit sane-find-scanner pour trouver l'intrus
$ sudo sane-find-scanner
[sudo] Mot de passe de emilien :
# 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.
found USB scanner (vendor=0x046d [Logitech], product=0xc21f [Wireless Gamepad F710]) at libusb:001:006
found USB scanner (vendor=0x0bda [Generic], product=0x0129 [USB2.0-CRW]) at libusb:001:005
# Your USB scanner was (probably) detected. It may or may not be supported by
# SANE. Try scanimage -L and read the backend's manpage.
# Not checking for parallel port scanners.
# Most Scanners connected to the parallel port or other proprietary ports
# can't be detected by this program.
Voila donc en plus du dongle USB que j'ai ajouté, l'intrus recherché hier est:
Realtek Semiconductor Corp. RTS5129 Card Reader Controller
En ce qui concerne l'idée de fedoix:
$ sudo simple-scan
-> pas mieux et aucun log dans la console
par contre, en SU, ça me donne un warning:
$ su
Mot de passe :

Et enfin pour didierg, j'ai relancé le install.sh sous scangearmp2-3.70-1-rpm:
[emilien@emilien-ge62-6qc scangearmp2-3.70-1-rpm]$ ./install.sh

Pour info, l'IP de mon imprimante est:
192.168.1.23
mask : 255.255.255.0
passerelle : 192.168.1.254
Aucun problème au ping (puisque l'imprimante fonctionne très bien en wifi) :
