Office Jet 4650. Error messages "connection to the compute has been lost or Scan application currently in use or an OCR application is not installed on the computer." I am also getting a pop up stating "HP Scanner 3 will damage your computer"
another pop up states "Failed to open a connection to the device"

I have the same problem with an HP Envy 4520 model. Was fine when I used it a week ago but now scanner does not work and HP Home says printer is off-line even though it prints just fine but will not scan. I'm not sure if this is an HP problem or a Windows 10 problem. Community thoughts would be appreciated since HP apparently has no clue. This all started after I recently gave HP permission to monitor my printer for improved operation.
