Hi JSimm and leo2.
@JSimm, sometimes, OS updates cause drivers to become corrupted. You may need to remove the printer, then uninstall the drivers (from the Apps & Features list; open it and search the list for Canon), then restart the computer (to clear the corrupt settings) before reinstalling it. The latest drivers are available, free of charge, at the MB2720 Drivers & Downloads page.
@both If you haven't yet done so, download and install both the latest version of the drivers and (on Windows) the patch for network scanning. They're available, free of charge, at the MF4880dw Drivers & Downloads page. If you're on Mac OS, you may need to install the printer driver, then remove the printer and then re-register it with the Canon-produced drivers to ensure everything works together properly.
If you can scan from the computer but not from the printer, check that the computer's security software and the router's firewall are allowing communications.

I fixed my problem. After downloading the driver installation file for the 4880dw printer on windows 10 the printer began to print but would not recognize the computer I wished to scan to. After much google study with no clear result on how to solve the issue, I just happened to locate the original user software disk that came with the printer and was used to orignally connect my other computers successfully. I ran the software that included and apparently loaded the MF toolkit. Voila! my new computer was recognized for scanning on the printer.

Like everyone else on this message thread, my scanner quit functioning within a few weeks of setting up my G7020 printer with Dell Computer with Windows 10.
This is my first venture with Canon, after being a long-time HP customer. So far, this has been a big mistake. It took me hours just to get my printer set up with my laptop. The Canon manual and the responses from the Canon help desk have not helped. Fortunately, the responses from other customers with possible work arounds have helped the most.
Still it hasn't fixed the problem. I noticed the first message was from 2016, and 4 years later, Canon still doesn't have a solution? I couldn't be any more frustrated. I had similar problems just getting my printer linked to my laptop. Time is money, and trying to get this printer to work has cost me so much.

I had a problem of no scanning with Canon 4880dw on both windows 7 and windows 10 machines. The printer worked. Downloaded and reloaded drivers from Canon website without success - until I found the original disk that came with the printer. When I attempted to reload the driver from this disk it said the driver was already loaded but the Canon Toolkit MF Network Scan Utility\CNMFSUT6.EXE did not seem loaded. After I loaded it - voila scanner recognized computers. So get the disk that came with printer or ask Canon to supply this utility...

Thanks for suggestion. What is frustrating is to make your solution work, I now have to purchase an external disc drive for my laptop.
I cannot believe how much time I have spent to get this Canon all-in-one copier set up and it still doesn't work for the most important purpose for which I purchased it. This has been an ongoing issue for Canon since 2016, per this thread, and they still have not come up with a solution for us to not have to keep erasing the software and then downloading it again?
I really appreciate your responding to my message. I will try to follow your suggestion if that is my only solution.
