Hi@BrunoGG,

Welcome to the HP Support Community! I'd like to help!

I see you are experiencing scanning issues with the HP DeskJet Printer. I apologize for the Inconvenience. 

I have a few recommendations 

• Restart the printer try to scan. If the issue persists, uninstall the app from your Windows 10 device through the All Apps list. In Windows, search for and open Apps & features. Click HP Smart in the list of apps, and then click Uninstall.
• Fix printing and scanning problems with HP Print and Scan Doctor, a free tool for Windows. Diagnose & fix any of the following scanning problems or error messages using the HP Print and Scan Doctor. Download HP Print and Scan Doctor.
• Disable the Firewall on your computer and try the network scanning again. Temporarily change your firewall/security settings to allow network connection. Your computer's firewall/security software may be preventing the network connection from being established.

after hours spent trying to fix it, I solved this problem: as I understood this printer only works if it is connected with wireless, and not with the cable.

My 3750 scanner worked happily on USB cable until about 2 weeks ago, since then it doesn't want to know. The print and Scan Doctor is useless, Windows help is hopeless, the HP Virtual Assistant needs shooting, It can print but it can do bugger all else.
Anybody a useless knackered 3750? I've given up on HP and will go to another maker.
