Googling  linux brother "simple-scan"  gets hits suggesting
users are having similar problems with that package.
Sane says brother scanners are "unsupported", but the above
brother.com url lets you download drivers that they say will
get the sane stuff working. But I'll give that simple-scan
package a try if I can't get Brother's documented procedures
working after a little more twiddling. If nothing else,
maybe simple-scan will fail in some way that better hints
at what's going wrong. Thanks,
