I have run into this problem after physically moving and then restoring the cables connecting my HP 2540 All-in-One Printer/Scanner/Copier to my W10 desktop PC. I welcome help in fixing the glitch.
FWIW.....the printer is connected to the PC by cable. All three functions worked before the move.
But now, although the HP device prints and copies as it should, it no longer scans.
When I call for a scan, I get a message "We can't find a scanner attached to your PC.. Go to PC settings."
Can someone please explain how I get to "PC Settings" or offer other suggestions? Thanks. batpark
