New sidebar can be confusing when you set Use native UI in your profile. But it still displays settings which you can predefine.

Thanks for the update and the new sidebar UI is wonderful.

However, when I use WIA as the driver, nothing happens after the progress bar ended. The exact scanner model is Epson Perfection V370. (Already tried turning off Exclude blank pages but the problem persisted.)

Expected behavior: the scanned images should appear in the window.

I found those messages in AppData\Roaming\NAPS2\errorlog.txt but no extra information is provided

The same configuration can work in version 7.5.2.0

So, now someone can add a profile from three places in the main window! I don't mind "Profiles" button. Also like the new profile sidebar, which gives a modern look to the app. But in the "Scan" button's drop-down menu, there's a "New Profile" option. It doesn't add any value other than visual clutter. You should remove this repetitive option from the "Scan" menu.

Hi!

Lower-right "notifications" are never cleared in GTK. Also the "Running OCR..." box never goes away even after 10 minutes, but when I save the PDF everything is OCR'd.

EDIT: Also the X button to close notification doesn't work.

Hi, drag and dropping pdf files to naps2 window isn't seem to be working on Windows 11 (exe installation).

[coderuk66]

After cropping an image the view is updated and the image looks like its cropped incorrectly. its not showing the full image. when the image is saved to a file it looks as I cropped it (thats the good bit).
I like the side bar view. It can speed things up when checking the profile settings.

On macOS 14.7: After the scanning process has finished, no preview of the scanned document is shown in the NAPS application window. NAPS 7.5.1 was the last version when this worked. I noticed the problem in 7.5.2 and now in 8.0 beta. So I went back to 7.5.1

[cyanfish]

Can you follow these instructions to collect debug logs with 7.5.2?

[TopstarBluecoat]

I did a scan with 7.5.2 while debug mode was on. Here's the result:

It looks like the problem has something to do with the profiles. If I use a profile for greyscale or black/white then the preview of the document is shown in NAPS. But when I use a color profile, it does not work.

[funkerwolf]

Just a great update, long time ago should have made such an interface. All that's left is to build a UWP version and update the design for Windows 11, it will be just awesome. But still there is a request, can you work on compatibility with Kyocera MFP? Very lacking in their support of TWAIN implementation, have to.... to use winscan2pdf instead of Naps2 to work with them. An example of such a MFP model FS-1025, very common in view of its cheapness and reliability, drivers (https://www.kyoceradocumentsolutions.com/asia/download/software/FS-1020_1025_1120_1125MFP_v35.zip) for it there are providing scanning over the network, just not all of them can not find.
And when will the ability to run as a service be implemented, so as not to keep the naps2 window running itself?

[coderuk66]

Some suggestions.

• In the sidebar profile view can we have the keyboard shortcut key (F function) shown? perhaps under the profile name.

• Is there a keyboard shortcut key for "Scan"? to scan using the profile selected in the sidebar. Prefer to just tap a key sometimes than reach for my mouse.

quirk/bug: After scanning the screen briefly switches to another window's app then back to show naps2.

[funkerwolf]

In scan mode via WIA on HP MFP M125 the result is not output, via twain is fine. The same on USB and Network connection. Checked on other HP models, it looks like scanning through WIA is broken. Rolled back to 7.5.2 via GPO with the 8th one removed. Everything is normal now.

Oddly after I removed another program I needed to reinstall, NAPS2 now starts so much quicker. its x4 faster startup (like it should be). see if stays that way. I'm using the portable installation (naps2-8.0b1-win-x64).
maybe installing another app fixed issues with the registry that were caused by naps? hence why its now starting lightning fast. can other users try this out see if it improves start up speed? just install an app or uninstall an app then reinstall the app. backup your app's settings / data before doing so of course.

[cyanfish]

The slow startup is related to Windows Defender scanning. In my testing it only happens immediately after installing NAPS2 or rebooting, subsequent starts should be fast.

I'm hoping that as the NAPS2 code signing certificate generates more reputation this might fix itself at some point. Or if you're so inclined you can add the NAPS2 folder to the Defender exclusion list.

[coderuk66]

makes sense. I only start up naps once and leave it open so a slow startup isn't much of an issue. I've gone back to 7.5.2 for now until the next beta release. I'm using Avira Free Security as my AV software. Was on the beta 1 for a couple of weeks just thought it odd when i saw it start up so fast as its never been that fast before.
