I have an all-in-one printer Epson SX130, wich I have just tried to install. I got the printer working with no problem, but I couldn't set the scanner up. I have had another all-in-one printer before (Brother DCP-125C), and had just the same problem, so I decided to try the same trick I used to do then, running the scanning program as super-user:
$ sudo xsane
Once again, it worked just fine, and I could use the scanner.
Anyhow, this solution is a little annoying, because I also have to change the permissions to the files I get scanning like this.
I have been searching the internet for solutions and got to know this must have something to do with user groups permissions, but couldn't find a satisfying solution. Is there anyone with an idea?
Thank you in advance.
