I'm new to Linux and installed Ubuntu 15.10 few days ago. I can successfully print on my Canon i-SENSYS MF4890dw, but when trying to scan with Xsane I get the following:
Failed to open device 'pixma:MF4800_10.237.93.145': invalid argument
As I have read some feeds from other similar threads, I've tried on Xterm:
scanimage -T
which returns:
scanimage: open of device pixma:MF4800_10.237.93.145 failed: Invalid argument
and
uname -r
which returns 4.2.0-25-generic.
