I know that there are issues with this family of machines. I have done 
some work with a MX492 (that is not yet merged) and it has very 
problematic ADF support.
I will drag out mine and try it with what you have above and see if I 
get the same.

In the meantime, could you let us know the versions of your SANE components?

scanimage -V
