WINDOWS HOME 11 conflict with CANON MF SCAN UTILITY

Anonymous
2024-12-05T13:40:23+00:00

I reinstalled Windows 11 Home on my computer. When I start scanning with the CANON MF SCAN UTILITY program, the following message appears: "Cannot communicate with the scanner. The cable may be disconnected, or the scanner may be turned off. Check the scanner status and try again. Scanner driver will be terminated."
I reinstalled the drivers again, reset the printer, modem. The problem is not solved.

The previous installation of Windows 11 Home worked without any problems.

Canon technical support informed me that the problem is in the blocking of the Windows 11 security system from sending information via WIFI.

I see that there are enough similar messages, but there is no solution. Please help solve this.

I have been frustrated by this issue also. I bought a new desktop machine and it immediately updated and installed Win11 24H2 on it. I then installed my Canon software for my printer MF750C and the MF Scan Utility would fail with the message mentioned many times in this thread.

I have installed all the latest updates and including the one Microsoft released 12/10/2024, KB5048667, but none of that made the scanner software work.

Now today I reinstalled just the drivers for the MF750C under the Imaging devices in Device Manager, and it started working, and has kept working as I think I have tested after rebooting at least 10 times today.

So bring up Device Manager, (right click on the Start Menu), expand Imaging devices, then right click your device, mine says Canon MF750C Series, (2 times). Now this part is important as I checked it twice and if you don't Disable the device first it doesn't seem to work right. So right click on the device and click Disable Device. My MF750C is listed twice here in Imaging devices, so be sure to Disable Device for both of them. Then right click on it again and select Browse my computer for drivers, then select Let me pick from a list of available drivers on my computer. Your printer/scanner should be in the list, make sure it is selected, then click Next.

Mine then came back and said Windows has successfully updated your drivers. Make sure you do this for BOTH of the devices listed there, at least if it lists two of them. Windows does say it updated the device driver. I'm not sure what it did for sure but it did something.

It doesn't say you have to, but I then rebooted my machine before I tried the software, but then the MF Scan Utility works! It has kept working for 2 days now, and after many reboots!

I don't know if this will work for everyone but so far it has worked for me. I have no ideas what made it work today.

Microsoft and Canon, (and apparently HP and Brother), need to talk and get this resolved for people!

    I agree there is conflict. I purchased a new printer that can scan on my old computer that is Windows 10, not updated. However, the scanner says it cannot connect with the scanner; the cable might be disconnected from my Windows 11 desktop. It is an expensive printer but has become useless because I cannot scan anything, but it will scan on Microsoft generic scanner only on PDF or picture; it does not have all the functions.

    Note that Canon released new drivers for Win10 64 bit and Win 11 on 09-Jan-2025.
    Installing the new drivers does prompt you to grant access to the device, restoring connectivity.

    Updated drivers - select your desired OS from the pull-down menu: https://www.usa.canon.com/support/p/color-imageclass-mf8580cdw?srsltid=AfmBOorKASQEygVGJEVDDqzOfS8eJDDMNmANIhCNgojq4hG3t7CIrXqI

    From the link:

    File Name

    MF8500CMFDriverV420WPusEN.exe

    File Description

    If you cannot scan over a network or with a USB connection in Windows 10/Windows 8.1/Windows 8, install the MF driver, restart (not shut down) your PC, and then install the following program. [Windows 32-bit & 64-bit] Patch for Network Scan, USB Scan
