I see there are others who have had this problem. Some resolved, others had to be replaced.
After a normal print, I lift the lid to insert a new piece of material, close the lid and the GFUI indicates Scanning… but stays that way. My only workaround is to shut the GF off for a bit, turn it back on and let it run all it’s initial diagnostics, then I’m good to go… for one more print. Problem returns each time.
I’ve checked the lid ribbon cable connections, cleaned the lenses, checked Wifi, and basically followed all recommendations suggested to other users. Is there (hopefully) a fix I’ve not yet read about? I’m full on in the middle of large Christmas order! Yikes!
