Need a scanner, price up to 1000 EUR.
- Excellent Linux support under Debian
- Automatic Document Feeder (ADF) for at least 20 pages in A4 format
- At least 300 DPI
- USB connection to computer
Nice to have:
- Only packages from Debian repositories required
- Fast operation (we have loads of pages to scan)
- 600 DPI or higher
- Optional scanning to USB stick without any computer
"Excellent Linux support" in particular means that we can easily start a scan from a tool like gscan2pdf, and it will scan all the pages in the ADF into a single PDF file. It should also be possible to scan some more pages after this and have them added to the same PDF file.
Conclusion: We bought the Brother ADS-3600W. It did not work out-of-the-box under Debian/buster, but we had to download a DEB file from Brother's homepage, which currently is
brscan5-1.2.2-0.amd64.deb. Installing this DEB and rebooting made all scan programs recognize the device. Of course, it would be much, much nicer if Brother offered a repository instead, so that updates would come via
We mostly use
gscan2pdf. It works fine in the range up to documents about 70 pages (scanning up to 50 pages at a time, since the scanner has a 50 page feeder). After this, it becomes very slow, almost unusable. We suspect this is a problem with program
gscan2pdf and not with the scanner or its driver. Waiting and hoping for a new version of the program.
We also received verbal confirmation from Epson that the Workforce DS-870 does work with SANE under Linux. This scanner has a 100 page feeder and would thus have been better. However, since Epson insisted on prehistoric communication (that is, via phone and not e-mail), this message arrived too late, after we already ordered the Brother. Maybe next time.
