I had the same issue and nothing worked until I tried below:
1) turn off the printer
2) remove all cartridges
3) turn on and it will say "ready to print"
4) insert all the cartridges again and test print
5) worked for me ^^
If you tried unplugging and plugging back in and it didn't clear the fault, you will need to call Support.
