HP smart app on andorid is no longer allowing me to printer scan documents

[Chappers71]

I can scan from the printer to the PC no problem and all other functions of the printer are working via the HP Smart app on my android phone but suddenly the Printer Scanner option doesn't work - it takes me to the screen where it says to place the document on the printer and press start but the start button doesn't become active.  The whole screen is non responsive with the exception of crossing out of it or selecting a different source which i don't want to do.  I have uninstalled and re-installed the app, I have switched off and on again (printer and phone) - NOTHING!  Please help.

@Chappers71, Welcome to the HP Support Community! I’m here to help.

I see that you are not able to scan using the HP Smart app.

Make sure the Android device and the app is up to date.

For more info on scanning, refer to - How to scan with an HP printer
