Question about Canon PIXMA MP780 All-In-One InkJet Printer
Welcome to Fixya
THE USB CORD IS IN THE PHONE JACK AND THE FAX THINKS THAT THE PRINTER IS "ON HOOK." At the back of the printer you have a column of jacks, the one on top has an icon of a phone and the one on bottom has a picture of an "L" or laptop. TAKE YOUR USB CORD OUT OF EITHER ONE OF THOSE, NO MATTER WHICH ONE IT MAY BE. What you may not have figured out by now is that there is a THIRD jack that is not anywhere near those two. If you're facing the front of the printer to the far right of the backside of the machine, there is this deep cavity that has your third, miracle jack in it. It's even more to the right than the two jacks I described previously and its icon looks like a sideways, three-pronged cactus. Plug the square end of the USB cord into that jack, and the In Use/Memory light should stop blinking.
Thank you for using Fixya!
