As discussed previously, several Fujitsu scanners are no longer supported in MacOs Catalina. Having tried ExactScan and VueScan, I ended up with “scanimage”. This is a command line tool and a frontend to the sane open source project. For example this command for my ScanSnap S510M scanner:
scanimage --device fujitsu \
--source "ADF Duplex" \
--page-width 210 \
--page-height 297 \
--mode Gray \
--resolution 150 \
--contrast 12 \
--batch=scan-$(date +%Y.%m.%d.%H.%M.%S)_p%d.tiff \
would generate tiff images. The resulting TIFF files can be converted to pdf using the “convert” tool from imagemagick:
convert -quality 40 -gamma 1.4 -compress jpeg scan-*.tiff scan-$(date +%Y.%m.%d.%H.%M.%S).pdf
Both sane and imagemagick can be installed with homebrew on the Mac.
Additionally, the scantailor-cli tool can be used for deskewing or textcleaner for cleaning up the images. The ScanTailor tool must be compiled though.
Thanks for this posting.
I’ve got scanimage working, but for one hitch: each scan take a considerable amount of time to execute.
From what I gather the cause of the delay is not specifying --device, which causes scanimage to search for a locally available machine.
The obvious solution: specify --device.
That’s the curious part:
--device fujitsu doesn’t work, even though the device being used is a a Fujitsu iX500.
"scanimage: *open of device fujitsu failed: Invalid argument*"
sudo scanimage -L returns
fujitsu:ScanSnap iX500:[s/n] (where [s/n] is a partial serial number of the scanner)
Unfortunately, none of the following worked either…
--device 'fujitsu:ScanSnap iX500:[s/n]'
--device 'fujitsu:ScanSnap iX500'
Question: How to properly specify --device for a Fujtsu iX500?
scanimage works if I leave out the --device option altogether, but each scan takes a long time to auto-discover the attached scanner.
Try “scanimage --help -d DEVICE”. This should return the device name to be used with the --device option. Good luck.
The solution, it turned out, was simply to run the command as super user under sudo.
