I have been scanning from my computer nearly 3-4 times a week. Today I have 2 documents to scan and my printer says  "Couldn't Connect To Scanner. HP Smart cannot Scan From This Printer"

Hi @Granny-H_66 ,

Welcome to The HP Support Community.  

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

I understand your HP DeskJet Plus 4152 printer suddenly stops scanning and shows the message "Couldn't Connect To Scanner. HP Smart cannot Scan From This Printer," there are a few troubleshooting steps you can follow to resolve this issue:

Basic Troubleshooting Steps:

Restart Both Devices:

• Restart your computer and the printer. Sometimes, a simple restart can resolve temporary communication issues.

Check Physical Connections:

• Ensure that the printer is properly connected to your computer via USB cable or connected to the same Wi-Fi network if you are using wireless scanning.

Update HP Smart App:

• Make sure you are using the latest version of the HP Smart app. If not, update it from the Microsoft Store.

Check Printer Connection:

• Open the HP Smart app and verify that your printer is listed and connected. Sometimes printers can lose their connection due to network issues.

Advanced Troubleshooting Steps:

Check Scanner Settings:

• On your printer's control panel, navigate to the scanner settings and ensure that the scanner is enabled and set up correctly.

Reinstall HP Smart App:

• If updating the app doesn't work, try uninstalling and reinstalling the HP Smart app. This can resolve any software glitches.

Check Firewall Settings:

• Occasionally, firewall settings on your computer can block the HP Smart app from accessing the scanner. Temporarily disable the firewall and check if scanning works. If it does, adjust firewall settings to allow HP Smart through.

Driver Reinstallation:

• Reinstall the printer driver on your computer. Sometimes, corrupted drivers can cause scanning issues. You can download the latest drivers from the HP website.

HP Print and Scan Doctor: HP Print and Scan Doctor

• Use the HP Print and Scan Doctor utility. It can diagnose and resolve many printing and scanning issues automatically.

Factory Reset (if necessary):

• As a last resort, you can perform a factory reset on your printer. This will reset all settings to their defaults. Refer to your printer's manual for instructions on how to do this.

Hi. I have the same issue today as does my colleague. There appear to be quite a few threads on this topic in recent days. If your issue is the same as mine, the printer appears to operate correctly and is connected. Printing from the computer and test pages print fine but it is specific to the scanner operation. I suspect this is something software-related due to an update to HP Smart, printer firmware or Windows in recent days. I have worked through all the usual fixes - reinstall HP Smart, reset + re-ad printer, etc but nothing appears to work.

Any help from an HP expert would be much appreciated. Thanks.
