The IJ utility works to scan, but rebooting the computer and turning off the printerr did not resolve the issue of scanning from the actual printer.  I have a TS5120 and have to continue to scan from the utility.

Hi lizbarnett.

If the IJ Scan Utility is scanning, but the operation panel of the printer isn't able to scan to the computer, then the computer's firewall or security settings are preventing the information from being pushed onto the computer.  Ensure the necessary ports and program exceptions have been added to your security software.  Refer to the security software's documentation and support for directions on adding exceptions.

If this is a time-sensitive matter, you may click HERE to search our knowledge base, or create/log into a Canon Account and register your printer HERE for additional support options.

Im having this issue now, as well.   Did anyone ever figure out why its happening?   Irritating when trying to do payroll.

It seems it's happening to lots of users, but Canon don't have the solution figured out.  I tried the suggestions from this forum and spoke to their support line, to no avail.  (It's clearly an ongoing problem, so I don't know why it says "solved" for this thread.)  The idea of going back to an HP (i.e. "Hopeless Printers") disturbed me to the point of giving the Canon Support Line another try.

This time it worked!  Full marks to the one who helped me through it:  even though he didn't know why it worked, the things he took me through did the trick.

What did it take?  Uninstalling the drivers, restarting the PC and disconnecting the printer, downloading and installing the latest drivers, and reconnect the printer to set it all up.

So if you can't get it to work, give the support line a call.  (The Canon one - even though you might be thinking of the Crisis Support Line.)

I hope your solution is permanent. I have done that solution three times, and it will work to scan a few pages, and then back to the error message. I finally took it out of the network, and cabled it to my primary computer with a USB cable. It all works that way, so the issue is a networking glitch of some sort. I have never been able to get Windows 10 to share files with other computers--also a very common complaint by users--so it's possible that Microsoft is the culprit, either inadvertantly, or as some have suggested, by design to push users to their cloud service for file  sharing. That sounds pretty sleazy even for MS, so I'll assume it's accidental. Either way, Canon should be able to program around the problem. My HP works fine, so . . .

Unfortunately, I've got the printer plugged directly to my computer as well. I'm not trying to connect through the network. I've still been getting the Cpnnect the Computer message, even with the cord. Will update if I have luck later today

[MrSquiggle]

Plowshares, you've got me crossing my fingers.

My printer is directly connected to the PC by USB cable.  It makes for fewer problems...theoretically.

I'm sure the Windows 10 updates are the culprit, as my problem started after one of their updates.  Software updates seem to be the cause of many app problems.

My Printer is a Canon Maxify MB 2720 and it prints just fine but when I try to scan wirelessly all I get are error messages.  I see this seems to be an on going problem have you found a solution yet?  The wierd thing is that I didn't have this problem til recently.  I'm running windows 10 on all of my systems, if that helps.  Here is a summary of my situation:

Can't scan to my laptop from the printer (Doesn't recognize the laptop)

Can't scan wirelessly (error codes in the utility)

I can print wirelessly to my MF4880DW printer from my computer but when I attempt to scan it says cannot connect. Need to solve this issue...

You won't get any satisfaction or support from Canon. The only solution unfortunately is to buy a new printer. I certainly won't be buying a Canon again. They work great for a few months, then the bugs start and never cease.
