Hello,  

When I try to login into the app HP Smart, I get the code  Error Code: UA_400_EB000U0100

So, I can't scan any of my documents. It was great with the HP Easy Scan before... 

This is not very practical. 

I'm on MAS OS Big Sur

@normboulanger, Welcome to the HP Support Community! I’m here to help.

I understand you are not able to scan using the HP Smart app from your Mac.

To assist you better, did you download the app from App Store?

1.     If installed from HP.com please delete from /Users/Username/Library/Application Support/HP Smart. Then delete HP Smart from the Applications folder and reinstall from the Mac App Store.
2.     If downloaded from the Mac App Store please remove /Users/Username/Library/Containers/HP Smart/containers.plist and then launch HP Smart from the Applications folder and go through the setup again.

Make sure the printer and the Mac are on the same network. You may refer to - Wireless Printer Setup

Update the printer firmware

Click here to download and install the latest printer firmware from your Mac.

Click here to know different methods of updating printer firmware.

Also, check for any software updates on Mac

Click the Apple icon > About This Mac > Software Update and install any available update.

If the issue persists, you may still use the HP Easy Scan app from App Store or Apple Image Capture.

Refer to - How to scan with an HP printer

Hope this helps! Keep me posted.

Hi Kumar, 

i recently bought the Mac Mini with the Apple Silicon Chip, can it be the problem? It’s working on my Old Mac of 2015 with the Intel Chip. 

do you have any solution?

@normboulanger

The Apple chip is not related to the HP Smart app. 

Did you try the steps mentioned in my previous post?

Keep me posted.

Yes, when I want to upload software, it keep coming back to the HP Smart app and I still get this message when I want to Scan... Why do I have to connect to scan??

Try using the HP Easy Scan app from App Store or Apple Image Capture to scan and check if that helps.

If you are still not able to scan, I think this issue needs some additional technical assistance that can be better provided through one-on-one interaction or a remote session with our HP Support team.

Please reach out to the HP Technical Support team in your region for further assistance. 

Keep me posted for any other assistance.
