Product: HP Smart Tank 515 Wireless All-in-One
Operating System: Microsoft Windows 10 (64-bit)

My printer does not scan anymore - in the HP App  there's info that my scanner is faulty. When I try to use it, I'm met with info that "scanner is already in use" when it isn't. I've tried troubleshooting it using the HP app, removing and readding the printer to the HP app,  resetting the printer, but none of it worked. What could be the issue, and how can I fix it?
