#663 Duplex option with WIA not working since 6.0.4 beta leveraging Fujitsu fi-6130

[Matt S]

Hi, firstly thanks for such an amazing program.
I have a Fujitsu fi-6130 scanner - and am on Windows 10 pro.
From NAPS 6.0.4 onwards, when using WIA version 2 with duplex option, only 1 of the 2 expected images is returned per scan. This also occurs with the current NAPS 6.1.2.25834 build. Reverting back to builds 6.0.3 and earlier, the WIA duplex functionality works perfectly returning both images/sides of the scan.

Adjusting the profile to use WIA 1.0, I get the error 80070057 WIA error code - and the scan cannot be made.

Screenshot attached shows some info.

Using Twain driver, everything works.

Having the same issues with my Fujitsu fi-5110C: Duplex scan is not working anymore. Also, scanning multiple pages won't work.
Looking at the changelog for 6.0b4, the change "Removed some obsolete WIA compatibility options" pops into my eyes. Is it possible to re-include the compatibility options for our dated scanners?
I rely on WIA (as opposed to Twain) to get scanning with the scanner buttons to work, so a fix would be great!
Thanks!

Same error for me. Scanner Fujitsu fi-6130 (USB, WIA, Windows 11), last version able to scan in duplex mode is 6.0b3. Any other (even beta 7) report following error:

Error message form log is:

Could it be fixed?

I have the exact same issue with a 5530C2. But I can add, that I have it only on one out of two systems. So it is propably related to some driver settings or something like that.
