I can't scan a document using the HP app. The app just says "printer not available" after I add the document to my printer and select "scan." My printer is online with my Wifi and a diagnostic test indicates there are no problems.

Hi @paulsprinter700,

 

Welcome to the HP Support Community!

 

Thanks for reaching out!

 

When the HP app says “Printer not available” during scanning, even though the printer is online and passes diagnostics, it usually means the scan service isn’t communicating correctly with the app. Printing can still work fine while scanning fails because they use different protocols.

 

Restart your printer, router, and phone
Turn off the printer and unplug it for 30 seconds.
Restart your router and your mobile device, then power the printer back on.

 

Uninstall and reinstall your HP app.
Make sure your app is updated to the latest version.

 

Re-add the Printer

Open the HP app, remove the printer from your dashboard, and re-add it using the Wireless Setup Wizard. Make sure your phone or PC is not connected to a guest network. 

 

Update Firmware

Kindly refer to this link to update your printer firmware.

 

I hope this helps

 

Take care and have an amazing day ahead! 🚀

Thanks so much for the quick response. Simply unplugging and replugging my printer worked this time.
