Olaf,
it's been a while, and I was busy solving more pressing problems. Now
I'm back again to tackle this scanning issue.

First thing I did was digging out my old laptop, on which Windows Vista,
Adobe Acrobat Distiller, and the original Canon driver is installed, and
did a few scans from the ADF just to make sure this is not a problem of
an aging scanner.
Next I cloned the Git repository in order to be able to freely change
between various versions to find one which is working for me by compil-
ing "sane-backends" myself. For a first test I checked out changeset
1942c5fd32a7 authored by Olaf Meeuwissen <paddy-hack at member.fsf.org> at
2020-01-26 10:56:34 +0000. However while running
./autogen.sh && ./configure
I got two warnings which I do not quite understand:
configure: WARNING: Group uucp does not exist on this system.
configure: WARNING: Locking feature will be disabled.
The group does in fact exist:
$ ls -l /etc/group /etc/gshadow
-rw-r--r-- 1 root root 755 2020-01-14 10:03 /etc/group
-r--r----- 1 root root 622 2020-01-14 10:03 /etc/gshadow
$ grep uucp /etc/group /etc/gshadow
/etc/group:uucp:x:14:uucp
/etc/gshadow:uucp:::uucp
$
So what does that mean? Do "configure" and "make" want myself to be a
memer of group "uucp" while I'm just compiling the stuff? For the time
being I'll go on with the compilation, will do
$ SANE_DEBUG_BJNP=127 scanimage ...
and will report back how it went.
Sincerely,
Rainer
