Samsung SL-C480W scans blank pages

[grasdubide]

Hi everybody,
I'm using the repository, on Linux Mint 17.1 KDE.
My new Samsung SL-C480W is recognized over the network and by USB.
When I start a scan with xsane, the scanner starts and sends something, everything seems to work.
Unfortunately, I only get blank images.
I've tried differents settings in xsane, different output formats, but I only get white pages.
The image is 100% full white, without gray or black points.

The issue occurs over the network and by usb.

Thanks !
