wierd white background with xsane
 

i just finished setting up my USB and i decided to test out my canoscan n670u scanner. i configured the scanner and everything but when i scan nothing in the scanner (or something) this is what i get: http://users.adelphia.net/~mksad/images/white-bad.jpeg

that's with nothing in the scanner! i was wondering if anybody experienced the same thing. thanks.
