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.
had this issue. windows 10 started getting worse... store apps no longer opened, etc. i did a re-install of windows 10 from microsoft (not laptop manufacturer). all was working for weeks until windows update (as this issue occurred before)... microsoft visual c++ 2010 x86 redistributable 10.0.40219 kb2565063.
this time, i just uninstalled and re-installed in this order with reboots in between each and scan is working. thought i tried this before and it didn't work but might not have done reboots in between (too long ago to remember!).
uninstall canon mf toolbox ####.mf##
install canon mf toolbox ####.mf##
if it stops working again, before uninstalling / re-installing, also try:
powering off your pc and printer
unplug the usb from your printer to your pc
powering on your pc and waiting until it's been up a minute or 2 (for services to finish starting)
powering on your printer and waiting until it's been up ~ 10 seconds
plug the usb from your printer into your pc
open the canon mf toolbox #.# manually
switch the printer to usb scan (if desired)
press the start button on the printer
Outstanding thanks kjv for refering us to Piers_A on 8-19-2015. I too was having this problem and this fixed it. Kudos to you and Piers_A. This needs to be broadcasted to everyone that has responded with this problem.
This solution works on my MF4270. Called Canon tech support twice, and all they do is uninstall/re-install drivers (which only fixes the problem until you reboot your computer and the fix is lost again). Canon tech support should really have pointed this fix out in the first place.
