     scanimage -T is meant to check the backend for correctness against 
SANE standard, it will badly fails on any scanner with a high dpi since 
it tries to scan at maximum resolution with 1 byte reads.
     It is usefull when writing a backend, but not for using it. Unless 
you are coding, don't use it.
