Comment 5 for bug 1731459

I did some testing with different colours. Maybe this helps to pinpoint what's actually going wrong.

I also found an interesting correlation with this bug: https://bugs.launchpad.net/ubuntu/+source/sane-backends/+bug/1712997
The visual artefacts are very similar however they are not in a straight line and they happen with the old driver (1.0.25) which is otherwise fine.

What I wasn't able to confirm yet is if the current stable release of sane-backends 1.0.27 might fix this or not. There are many dependencies which make it impossible for me to replace libase1 with libsane. You can get it here if you are able to work around the dependency issue: https://launchpad.net/~rolfbensch/+archive/ubuntu/sane-release?field.series_filter=

btw: This also happens with CanoScan LiDE 200 btw. I marked the report for 200 as a duplicate of this report since yours was reported earlier.
