"scanner in use" error message for OfficeJet Pro 8710

[PattEv]

We have successfully used our OfficeJet Pro 710 printer for scanning for years. Recently, we started getting "scanner in use" error messages when we try to scan, regardless of how we attempt the scan (HP Smart app, from Control Panel, etc). We can't use the scanner. We've tried uninstalling everything, reinstalling, and no matter what, are stuck in this "scanner in use" error loop. I see many others have had this problem but do not see any proven solutions. Help! We didn't change anything, and it just suddenly stopped working (probably with a Windows update). Any help would be SO appreciated.

Hi @PattEv 

Welcome to the HP Support Community! We're here to help you get back up and running.

Thanks for laying out the situation so clearly. It’s genuinely frustrating when a reliable scanner suddenly stops working and throws a persistent “scanner in use” error—especially when nothing was intentionally changed. 

Let’s work through a structured recovery approach to help resolve this.

1. Power Cycle the Printer

• Turn off the printer and unplug it from the wall.
• Wait at least 60 seconds.
• Press and hold the Power button for 15 seconds while unplugged.
• Plug it back in directly to a wall outlet (not a surge protector) and power it on.

 

2. Check for Pending Firmware Updates

• Visit the HP OfficeJet Pro 8710 support page.
• Download and install the latest firmware for your printer.
• Firmware updates can resolve compatibility issues with Windows 11.

 

3. Remove Conflicting Background Services

• Press Ctrl + Shift + Esc to open Task Manager.
• Look for any HP-related services (e.g., HPScan, HPNetworkCommunicator) that may be running.
• End those tasks and try scanning again.

 

4. Reinstall Full Feature Software

• Uninstall all HP software from Settings > Apps.
• Restart your computer.
• Download and install the Full Software and Drivers for HP OfficeJet Pro 8710.
• Avoid relying solely on HP Smart—use the full suite to enable full scan functionality.

 

5. Enable ‘Scan to Computer’

• Open HP Printer Assistant from your desktop.
• Go to Print, Scan & Fax > Scan > Manage Scan to Computer.
• Click Enable.

If the issue persists even after these steps, it may be worth checking whether the scanner is being blocked by a Windows security policy or third-party antivirus software. 

Let me know if you'd like help reviewing those settings. We’ll get this sorted.
