The problems has disappeared. xsane and scanimage work fine now: - The xsane gui offers scan resolutions up to 9600 dpi - No compression artefacts, tested with 1200 dpi - No error messages are displayed by xsane
The reason is a mystery, neither any sane nor brscan related packages seem to have been updated in the meantime, but the options xsane offers and how it behaves are clearly different. I can't remember having touched any scanner related configuration since then. However, even though there is only one device, which is connected via WLAN, xsane offers me two "devices" upon startup: Brother *b20210821 MFC-L2710DW [brother4:net1;dev0] and ESCL Brother MFC-L271 flatbed scanner [escl:http://192.168.178.26:80] With the first "device", "Brother *b20210821", scanning works fine, with the second device "ESCL Brother MFC-L271", the old problems occur. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1940754 Title: Scanned images are deteriorated by compression artifacts with Brother MFC-L2710DW To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/sane-backends/+bug/1940754/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
