Thanks for your efforts @gunnarhj. I'm glad that the fix helps many
users. If I come across any hack that solves the issue on my machine,
I'll update here.

genesys_gl847 scanners produce a black band in scanned images on

[Impact]
When using a Genesys GL847 scanner, the documents get disfigured by a
discolored bar. The proposed uploads should fix the issue. They are
available in this PPA:
https://launchpad.net/~gunnarhj/+archive/ubuntu/sane-backends
[Test case]
1. Install the libsane (libsane1 in bionic), libsane-common
and sane-utils packages from {bionic,disco]-proposed.
2. Use an affected device to scan, and find that the issue is
no longer present.
[Regression risk]
Upstream commit, focused bug fix => low regression risk
[Original description]
On Windows it works but on my Ubuntu 17.10, 18.04 and 18.10 I see a
black band on scanned image. The scanner is Canon CanoScan LIDE100.
Libsane version is 1.0.27-1~experimental2ubuntu1

@gunnarhj I tested the ppa and bionic-propsed a machine with fresh clean
install of bionic with CanoScan LIDE 100. The issue is *not* fixed on
this machine.
Here are the details of my testing:
I switched back and forth between distro-default, ppa and bionic-
proposed versions of libsane-common (and libsane1), restarted the
machine etc.
PPA
After adding ppa, I run apt upgrade which updated these libsane-common,
libsane1, sane-utils packages to
```
libsane-common/bionic,bionic,now 1.0.27-1~experimental3ubuntu2.2~ppa all
[installed,automatic]
libsane1/bionic,now 1.0.27-1~experimental3ubuntu2.2~ppa amd64
[installed,automatic]
sane-utils/bionic,now 1.0.27-1~experimental3ubuntu2.2~ppa amd64
[installed,automatic]
```
I did a test scan. Colored bar still appeared. I restarted the system
(or should I have restarted some sane service?). Tried scanning again.
Issue still exists.
To go back to distro default, I removed the ppa and libsane-common. This
removed a whole bunch of dependencies including ubuntu-desktop and
simple-scan. Reinstalling ubuntu-desktop brought libsane-common etc
back. Scanned a page again to see if there are any surprises. None. The
problem still existed.
BIONIC-PROPOSED
I enabled bionic-proposed channel repo. It showed a whole bunch of
updates. I had to pin the packages and install libsane-common/bionic-
proposed and sane-utils/bionic-proposed.
package versions after this:
libsane-common/bionic-proposed,bionic-proposed,now
1.0.27-1~experimental3ubuntu2.2 all [installed]
libsane1/bionic-proposed,now 1.0.27-1~experimental3ubuntu2.2 amd64 [installed]
sane-utils/bionic-proposed,now 1.0.27-1~experimental3ubuntu2.2 amd64 [installed]
The problem persisted during immediate scan and after a restart.

@gunnarhj I have `CanoScan LiDE 100` scanner with this problem on
18.04.3 LTS (bionic). I tried the above mentioned PPA. It does not solve
the issue.
`libsane-common` version is `1.0.27-1~experimental3ubuntu2.2~ppa`. I see
version `1.0.27-3.2...` for later ubuntu versions which is not available
for bionic.
If the fix is posted in PPA for bionic, I can verify and provide the
status here.
