I have a MF4570dn, and recently upgraded from Windows 8.1 to Windows 10.
I can no longer scan using the MF Toolbox utility. I had MF Toolbox 4.9 installed before the upgrade, and it worked just fine. After the upgrade, I get "Cannot communicate with the scanner" error dialog:
I thought I would try to reinstall the MF Toolbox utility, but there are two problems.
1) The downloads page shows no downloads for Windows 10 for this printer. This should be updated.
2) I downloaded the one for Windows 8.1, and tried to reinstall, but it just hangs at the "Processing Installation" screen:
I've also tried to uninstall the existing MF Toolbox first, and it also hangs at this same dialog.
I've also tried various other things without success:
- Connecting via USB instead of Network. It detects the scanner, and MF Toolbox can switch to that device, but it still gives a communications error.
- Trying the built-in Windows Scan app instead of MF Toolbox. It uses the WIA driver. It barely starts to scan, then immediately cancels.
Please Canon - forward this to your engineers and provide a fix asap. I cannot use my scanner on Windows 10.
(I can use the printer functionality just fine.)
Solved! Go to Solution.
Thanks. My model's links are different, but the new software appears to work.
Also, to get the old toolbox uninstalled, I had to reboot into safe mode. Otherwise the uninstaller just hung. Then booted back into regular mode, removed all traces of the existing printer, then reinstalled the new software and it works great.
Exactly the same problem is preventing me from working!
Scanning directly from device is impossible with the current Canon MF Toolbox 220.127.116.11.mf18 !
What is the problem, I am not sure. But it DID work with previous win 10 updates, and after it updated last month it stopped!
This is the error every time I choose my PC from the MF 6140dn!
I can manually start up the stupid toolbox and it would scan from the software, but it won't when I send scans from my device!
inb4 "Hurr durr, try the common fixes"
I've already tried the following:
Uninstall with wipe of LEFTOVERS: drivers
Uninstall with wipe of LEFTOVERS: MF toolbox
Install them again with restarts, different versions, different order.
The "Fix" patch for the network and usb scanner didn't work. (NetworkUSBScanPatchEN.exe)
Firewall has exceptions for:
%ProgramFiles% (x86)\Canon\MF Toolbox Ver4.9\MFTBOX.exe
%ProgramFiles% (x86)\Canon\MF Toolbox Ver4.9\TBOXCFG.EXE
%ProgramFiles%\Canon\Canon MF Network Scan Utility\CNMFSUT6.EXE
Firewall was turned off. Didn't help me.
Wiped clean Windows/Twain_32 directory, didn't work.
Tried installing on another 64bit win 10 machine. Didn't work 😞
You may want to try uninstalling your antivirus software. It helped me few months ago (I had Kaspersky Total Security).
Two times reinstalling last Windows update brought Toolbox back to work. (but it didn't helped me during lat few updates)
What's interesting is that when Toolbox stopped working, Windows Update was the thing that brought it to life (2 updates from june to july). August update killed it again...
I recommend to install Remote Desktop on your phone or tablet, and use it to scan when you're next to your printer - it always work and you won't loose your time for Toolbox anymore...
After the last Windows 10 Update (at the beginning of this month - it was KB4346783) scanning from device and using MF Toolbox without administrator priviliges is possible with no problems. I didn't take any other actions to restore those functionalities...
Maybe it will also "repair" the issue in your case...
Thanks, GregoryNazar! It appears MF Toolbox is working for me again after a long time.
For others' benefit, I don't have KB4346783 listed in my Win10 Update History, so it seems likely it was one of the following:
- 2018-09 Update for Windows 10 Version 1803 for x64-based Systems (KB4100347)
- 2018-09 Cumulative Update for Windows 10 Version 1803 for x64-based Systems (KB4464218)
- 2018-09 Update for Windows 10 Version 1803 for x64-based Systems (KB4456655)
I'm happy it worked.
Just be advised: next update may crush it 🙂 Few months ago Windows Update also helped me, but update that came about two months later seized scanning functionality. If that happens, you should try opening Toolbox with administrator priviliges and for remote scanning (from your Canon device) try Remote Desktop.
I just had to rebuild the operating system on one of the computers on my 4 computer network 2 days ago and wasn't even able to get the Canon Toolbox to Operate - The same thing everyone else is talking about. "A Supported Scanner is not installed etc....". With that I did a complete removal and reinstall of the drivers along with the patch that on the Canon website. <The mark of insanity is when you continue doing the sam thing expecting to get different results.> I reinstalled it twice and now not even the Canon Toolbox Icon shows in the Apps on my desktop.
There is a "Canon Office Printer Utility"icon that shows up in my apps (I believe that it was something that Canon's Web Site told me to download. When I go to that app it responds but nothing happens.
So now yesterday morning I scanned several items from my other compluter and then in the afternoon it started giving me the same message. It was then, after reading all of this business that I put it together that Yes-I like any good microsoft owner had performed an update midday yesterday. So now I understand why Microsoft is in such low regard by so many people.
At this point at I have a worthless Icon on the one computer and none on the other so I guess I won't be doing any scanning until someone develops a fix for this! I'm not dumb, but I'm not extremely fluent the in's and out of all this IT jargen and need these Guru software people to give me a fix that can be easoly explained in a few steps!
Pleeeeeeeeeease Canon and Microsoft gets your ducts together and stop wasting our time and Money!!!!!!!!!!
