Description Olga 2025-03-18 08:38:11 UTC
STEPS TO REPRODUCE
1.  Connect your scanner(s) with ADF/ADF Duplex to your computer with USB cable/Wi-Fi/Ethernet 
2.  Open Skanlite -> 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 Skanlite

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

Is this Skanlite or Skanpage?
(you do not have a list of pages in Skanlite)

What scanner do you have?

I use Skanlite. 
When you scan several pages with mode "ADF"/"ADF Duplex" in Skanlite, it opens separate windows with skaned pages. 
So issue is when scanning is completed, only one side of the sheet/one page is displayed. New window doesn't open automatically with the second side of the sheet/second page after saving the first image. So you have to go to"Acquire Image" window and click "Scan" button to get the second image.

Hmm... I can't find an "Acquire Image" button or window with Skanlite.
Can you send a screenshot?

And for clarification:
Is it so that you only get one side of all pages and have to scan a gain to get the other sides?
or
Is it so that you only get the one image -save popup window and have to scan again to get the rest?

(And if it is a multi-page document that you are scanning, I think Skanpage might be the more suitable alternative from the KDE world.)

Sorry for disinformation, when I used phrase "Acquire Image window", I was talking about Skanlite's main window (Please refer to screenshot)

I get only one image-save popup window after scanning.  I click "Scan" button to get the others. Please note, scanner doesn't scan again.

Actually I've already raised the same issue for Skanpage - https://bugs.kde.org/show_bug.cgi?id=501367

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)
