Description Olga 2025-03-18 08:46:31 UTC

STEPS TO REPRODUCE
1.  Connect your scanner(s) with ADF/ADF Duplex to your computer with USB cable/Wi-Fi/Ethernet 
2.  Open digiKam -> Import -> Import from Scanner -> Select Scan source- "ADF"/"ADF Duplex" -> Scan several pages

OBSERVED RESULT
When scanning is complete, only one side of the sheet/one page is displayed. The others will be displayed if you open the "Acquire Image" window again and click "Scan".

EXPECTED RESULT
Once scanning is complete, all scanned pages are displayed in digiKam

SOFTWARE/OS VERSIONS
Linux/KDE Plasma:  ALT Workstation K 11.0 Beta
KDE Frameworks Version:  6.10.0
Qt Version:  6.7.2

ADDITIONAL INFORMATION
I've tried such softwares as Simple-scan (https://apps.gnome.org/en/SimpleScan/) and XSane (https://wiki.ubuntuusers.de/XSane/) and haven't faced with this problem

Also I've noticed 2 new behaviours:
1. I only get one side of all pages and have to scan a gain to get the other sides. This behaviour applicable for Oki MB472 and Avision Scanner AV 186+, when they are connected with USB cable
2. This issue reproduces for OS with non English language ( for example Russian, Ukrainian)
