Suddenly I can print but not scan using HP Smart.

I have already uninstalled and installed HP Smart.

Any advice?

Hi @SantPere,

Welcome to The HP Support Community.  

Thank you for posting your query, I will be glad to help you.

I understand you are facing an issue  with the scanning issue with your HP DeskJet 2720e All-In-One Printer

Here are a few steps you can try to resolve:

Restart Devices: Turn off your printer, computer, and router. Wait for a minute, then turn them back on.

Update Drivers: Ensure your printer drivers are up to date. You can download the latest drivers from the HP support website.

HP Print and Scan Doctor: Download and run the HP Print and Scan Doctor tool. This tool can diagnose and fix many common printing and scanning problems. HP Print and Scan Doctor

Windows Scan App: Try using the built-in Windows Scan app to see if the issue is specific to the HP Smart app. You can find it in the Microsoft Store if it's not already installed on your computer.

Firewall and Antivirus Settings: Ensure that your firewall or antivirus software is not blocking the HP Smart app or the scanning process. Temporarily disable them to test if they are causing the issue.

Check WIA Service:

• Press Win + R, type services.msc, and press Enter.
• Locate "Windows Image Acquisition (WIA)" in the list.
• Make sure the service is running. If it’s not, right-click on it and select Start. If it’s running, right-click and select Restart.

Check Scanner in Device Manager:

• Press Win + X and select Device Manager.
• Expand the Imaging devices section.
• Right-click on your scanner and select Update driver.
• Follow the prompts to update the driver.

Reset the Printer: Perform a full reset of your printer:

• Turn off the printer and disconnect the power cord.
• Wait for 60 seconds.
• Reconnect the power cord and turn on the printer.
