HP 4650 Scanner won't scan as it says its in use but isn't. Unplugging didn't help to scan. Help!

My HP 4650 all in one won't scan. It says that it is "in use" but it's not. Unplugging and restarting did not reset the scanner. What do I do? Is there a phone number for HP help? Thanks in advance.

Hi @rworth,

Welcome to The HP Support Community.  

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

I understand the issue where your HP OfficeJet 4650 scanner says it’s “in use” can often be resolved with a few troubleshooting steps. Here’s how you can fix it:

Step 1: Restart Your Printer and Computer

1. Power Cycle the Printer:
   • Turn off the printer and unplug it from the wall outlet.
   • Wait for 2-3 minutes, then plug it back in and power it on.
2. Restart Your Computer:
   • Reboot the computer to clear any lingering tasks that may interfere with the scanner.

Step 2: Check Scanner Software

1. Update HP Smart or HP Scan Software:
   • Ensure you are using the latest version of the HP Smart app or HP Scan software.
2. Reinstall the Scanner Driver:
   • Uninstall the printer from your computer.
   • Download and reinstall the drivers for your printer from the HP Support website.

Step 3: Reset the Scanner in Windows

If using Windows:

1. Stop the Windows Image Acquisition (WIA) Service:
   • Press Win + R, type services.msc, and press Enter.
   • Locate Windows Image Acquisition (WIA) and click Stop.
   • Wait a few seconds, then click Start to restart the service.
2. Run the HP Print and Scan Doctor:
   • Download the HP Print and Scan Doctor and run it to diagnose and resolve scanning issues.

Step 4: Try Scanning from Another Device

• Test scanning from a different device (if available) to rule out an issue with your computer.
• Use the HP Smart App on your smartphone or tablet to attempt scanning.

Step 5: Factory Reset

If the problem persists:

1. Perform a factory reset on your printer:
   • Go to the printer’s Settings Menu.
   • Navigate to Printer Maintenance > Restore Factory Settings (specific steps may vary by model).
