I have a Dell-Precision 5510 laptop with Ubuntu 14.04 installed, and Samsung SCX-4729FW with combined copier+printer+scanner. Samsung is USB-connected directly to the laptop. I can print out my files from the laptop to printer, but when trying to use scanner (via Xsane command or icon) get a response "no device available". I tried to do it using "sudo", but my comp warned me it is dangerous, so i didn't continue.
My /etc/modprobe.d/blacklist.conf doesn't have Samsung SCX blacklisted. My /home/(myID)/.sane/xsane have these files:
Hewlett-Packard:ScanJet7400c.drc
SAMSUNG:SCX-472xSerieson10.0.0.20.drc
SAMSUNG:SCX-472xSerieson192.168.1.20.drc
SAMSUNG:SCX-472xSeriesonUSB:0.drc
xsane.mdf
xsane.rc
So I guess I have all the right drivers. Still, "no device available"... What can I do about it?
sudo scanimage -L
list the Samsung? (It's safe to run that withsudo
.) – Stephen Kitt Jan 8 '17 at 22:28
