MF Toolbox doesn't work on Windows 10

[mj1856]

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.)

Please note: When I did reinstall the Toolbox app and the drivers for the Canon MF4150 printer, Windows crashed (actually it suddenly reboots). "Your PC ran into a problem and needs to restart. We're just collecting some error information and then we'll restart for you"  It is fairly quick reboot but it might relate to the problem of getting 32 bit instead of 64 bit drivers from Canon. Once it restarts Win 10 seems to load the right version.

The Canon and MS apps worked afterwards but if you are in the middle of something, you will loose it. I haven't noted any other problems but the coincidence of dates and times of the reboots are statistically significant. This also shows clients that there are obvious incompatibilities between products and software that fall into no man's land that no one is taking any responsibility for.

When you ask Microsoft Community about these sudden reboots, you get this kind of response.

Thank you for posting your query on Microsoft Community.

"With the issue description, I understand that your Windows 10 computer is crashing and giving critical error messages on it. I will certainly help you in getting this issue resolved.

 This issue may occur because of any software conflict or incompatible / corrupt display or graphic driver. Let’s follow the below mentioned steps and check if the issue resolves"

Hopefully, this might give some people a heads up if Windows reboots suddenly after you install the Cannon apps or drivers for the wrong PC configuration.

Don't get caught up in no man's land where one company points to another company as the source of the problem. It will waste your time. Like me, you may have downloaded the wrong file for your system.

Hi James,

Entered MF4150 but did not get the sequence you mentioned. Also note that this patch is not available at  the canon.ca - website under drivers and support, therefore I missed it.  At the usa.canon.com website  I get Step 1 Support and Drivers, then Step 2 Select Model.   When I click GO  I get the Drivers and Downloads options again. Operating system seems to be automatically selected with the recommended driver. There is also a 32 & 64 bit driver. Does the patch work with either driver??

Thanks.

Hi @al1,

There is a recommended patch to install if you are having issues scanning after upgrading to Windows 10 for the imageCLASS MF4150.

Let's perform the following steps to download and install the scanning patch.  Note:  If Microsoft had an update it may be necesarry to rerun the  scanning patch again.

1.  Visit Canon's website at: http://usa.canon.com/support

2.  Type  MF4150 in the "Enter a Model Name" box and click search.

3.  On the Support page for your unit, click the 'Drivers& Downloads' link in the middle of the page.

4.  Select "Operating System"

5.  Under the "Drivers" tab section click on the file named "Windows 32-bit & 64-bit] Patch for Network Scan, USB Scan".  After reading the details and disclaimer, click 'I Agree to terms.  Download and save the file to your computer.  Once the download is complete, double-click the file from its download location to begin the installation.

If you had it working before on Windows 10 but it stopped working after a windows update which happens to me frequently, the way I get it working again is re-install the printer driver.  I just give it a new name, it warns me that this kind of printer is already installed but I install anyway.  After that the toolbox utility is able to find the scanner again.  Might help some of you out there.

TY,

Follow James' instructions above again. Install the printer drivers first and make sure the printer is working, then install the MF Toolbox app last.

My Canoscan 4400F used to work with Windows 10 but after an update it stopped.  I followed these instructions which then allowed it to scan again.   I don't know who the author is so can't credit them but here's their website.  http://www.polarsys.ca/docs/hardware/canon/index.html

----------------------------

I have a Canon CanoScan 4400F Scanner and the other day I was unable to get it to work.  I use the Canon software CanoScan Toolbox to operate the scanner and when trying to scan I was getting the following error message:

---------------------------
CanoScan Toolbox
---------------------------
Unable to open TWAIN source
Please check connection
Then re-start Toolbox
---------------------------
OK  
---------------------------

Searching the Internet for this problem turned up several people having the same problem and several solutions which looked like they may or may not work.  One of the recommended solutions was to make sure a certain folder path is in your PATH environment variable.  As it turned out this was the problem, so here is how to add that path back into your environment variables.

First, determine the correct path to add into the PATH environment variable.  Look in C:\Windows\twain_32 and there should one other folder in there.  In my case it was  named CNQ4803.

This is the path that is needed to be added into the PATH environment variable.

C:\Windows\twain_32\CNQ4803

Now, follow these instructions to get to the dialog to modify the PATH environment variable.

Control Panel > System > and then choose Advanced System Settings in the left hand column.

This will bring up the System Properties dialog (it should already be on the Advanced tab).

At the bottom of this dialog is an Environment Variables button.  Clicking this button will bring up the Environment Variables dialog.

In the bottom panel, scroll until you find the variable named Path.  Select this one and then hit the Edit� button to bring up the Edit System Variable dialog.

In the Variable value text box, scroll all the way to the right and then add in the path C:\Windows\twain_32\CNQ4803 that was determined earlier.  Make sure to separate this value with a preceding semi-colon.  And also be careful not to make any other changes to this value.

Now OK your way out of all of the dialogs and CanoScan Toolbox will now work as expected.

Sometimes an MF Toolbox or Windows 10 update will stop the scanner function. When that happens go to Control Panel and open System and on the left open Advanced Settings and then open Environmental Variables. Next go to the lower System Variables box and highlight Path. Next click New. Then find the current location of the Twain drivers under C:\Windows\ and enter the path to the Twain folder. The last folder should be the series of your printer. Mine was MF4100 for my MF4150. The problem is that the scanner can't find its drivers and this solves the problem.

I apologize of this information has already been posted.   For my scanner (MF4770n), there is a software patch on the Cannon web site where you download drivers.   Instructions are to install the dirver, restart the computer, and then install the patch.  Worked for me.   Says that the patch might have to be applied again if windows 10 is updated.
