won't be necessary, see below.

o.k. If no scanner-module is loaded there is no need for further
configuration with blacklists.

If I get you right, you installed the new SANE over the existing one
(windows-style).. However, it's strongly recommended to wipe out a earlier
SANE-installation cleanly from the harddrive before installing a new
version. Either with 'rpm --erase=sane1.0.16.rpm', or 'make uninstall' or
with the setup-program of your distri, depending on the kind of the
original installation. You mentioned, you've done the installation with
rpm, so it would be the first option.

The Canon Lide 25 should cause no problems with SANE. And it seems your
SANE-installation isn't really clean. So I would remove the whole
SANE-stuff completely and do a entirely fresh setup. Try the first scan as
