Hello, my MG6200 is not scanning to the computer or saving straight to email (like it used to).

 I am running the printer of Mac 10.11.6. 

When I want to scan to attach to an email or send to the PC, it comes up 'Select PC' and it only has local (USB) as an option. Previously it used to have our PC listed as an option. I used to be able to send to the PC or attach to an email. I can print wireless, so I know that the PC and printer are connected. It is so frustrating having to save to a USB then connect the USB to the PC to get the scanned documents.
