More information: I think the error message was a red herring. It appears to be an artifiact of the initial device probe and vanishes if I uninstall all the HPLIP related packages.
I'm growing suspicious of something in the SANE initialization process. I discovered by accident that if I run a scan using Xsane, exit that program and re-start gscan2pdf it springs into life and I can run sheetfeeder scans. I think this is why updating my version of gscan2pdf appeared to fix things last time around. I had tried with Xsane after fruitless attempts using gscan2pdf and never went back to the latter until after I upgraded. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/974347 Title: Blank scans in sheet-feed operation To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gscan2pdf/+bug/974347/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
