Scanner stopped working on Pixma mg3150

[Doodledebs]

HelP!!!!!

My printer will no longer let me scan, was absolutely fine - went to scan something but now comes up with the message :-

"To get started, connect a scanner"

I have not changed anything so should still work.  I ran the troubeshooter and it came up with the attached.

Nothing has changed, it is the same PC and the same printer.
