Fujitsu fi-4120C no duplex results in 1.3 on linux
Hi @jflesch, in libinsane#26 (comment 669868) you said that the duplex scan for the above model should already work in 1.3.
However, I am running 1.3.0-2 from the arch community repository, where paperwork does not display two scanned pages when scanned in duplex. However, the setting for the source results in significantly different scan time either for duplex or front/back, so the scanner itself is most likely doing the correct thing, what I also can see from the logs. Back and front separately are also correctly scanned. Somehow in a duplex scan paperwork seems to ignore the second scanned picture.
I noticed also in ironscanner when I submitted my scanner data, it did report that it scanned two images, but in ironscanners result, only the first one has been submitted as an image.
I see one suspicious warning after the scan:
