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. ** Attachment added: "color test" https://bugs.launchpad.net/ubuntu/+source/sane-backends/+bug/1731459/+attachment/5027778/+files/image_error.png -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to sane-backends in Ubuntu. https://bugs.launchpad.net/bugs/1731459 Title: Black band in scanned images Status in sane-backends package in Ubuntu: Confirmed Bug description: On Windows it works but on my Ubuntu 17.10 I see a black band on scanned image.
