MF Scan Utility Cannot Communicate with scanner -ImageCLASS MF644Cdw

lonquist — Tue, 11 Feb 2025 18:25:10 GMT

I have 2 computers on my network that have an error when trying to scan to my MF644CDW Printer/scanner.

It says "Cannot communicate with the scanner. The cable may be disconnected, or the scanner may be turned off. Check the scanner statue and try again. Scanner driver will be terminated."

I can print to the printer and the scanner selector software sees the printer/scanner and when I install the MF Scan utility software it sees the scanner. It works fine from other computers on my network, but not 2 of them. All windows 11 computers. I have tried everything I can think of like disabling the firewall and security settings. What could be causing this and how can I fix it?

Greetings,

Please click the start button on your windows desktop. After you click, type winver and press enter. What Feature release of windows are you running? Example 23H2, 24H2?

Do you have 3rd party anti-virus installed?

Did you install the MF Scan Utility v1.21.0.2?

Version 24H2 (OS Build 26100.2314) and yes v1.21.0.2

No 3rd party antivirus installed

Also, the Windows Scan app works fine so it has to be the Canon MF Scan Utility app.

We're having the same issue except the printer is a MF751. The Windows ScanApp worked once but never again. We've uninstalled and reinstalled about three times with no luck. The Canon MF733 they had before worked just fine but it died.

Have you had any luck since yesterday?

I am also having the same issue with MF451dw. Two of my computers on the network get this error message, and I believe they both happened after a Windows 11 update. I can print but not scan. Reinstalled the drivers and MF Scan Utility several times with no resolution.

I forgot to mention that the Windows 11 Pro workstation is 24H2. We tested a fresh install on a 23H2 workstation and the software works fine.

In the last 2 weeks the number of posts regarding this has increased. One user reported success using 24H2 on 3x systems.

I'm afraid this is something to do with 24H2 feature release as there are posts about it on Microsoft's community that include multiple printer / scanner manufacturers.

I'm going to raise this internally with the Illuminary group.

Just purchased imageCLASS MF455dw and experiencing the same issue connecting to network scanner using MF Scan utility. Most certainly something to do with Win11 24H2 feature release as mentioned throughout this thread (and others). I did see someone suggested using Windows Scan Utility and that connects as expected. Will need to continue to use until MS fixes what they broke.

My client uses the scan-to-computer function from the printer itself, and that doesn't work using the Canon software. I will have them try using Windows Scan Utility, but my guess is that something with the driver is still broken.

Hello, first of all I'm disappointed in Canon. Upon buying this printer MF465dw. Most people say the set up is easy as drinking water. Upon finding out, the scanner App as directed to installed is the most difficult thing to set up.

I keep getting error on my Window 11 PC: 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.

Also, I'm not sure why the scanner is separated from the Canon Print App on my desktop. I thought the scanner option should be in the app to give customer the ease to do everything from the app on their desktop?

If anyone from the Canon team has a easy fix solution to this error, please reply. Sorry to say, it is disappointing. The scanner app Canon MF Scan Utility recognized my scanner so I'm not sure how it's not connected.

I have the same problem. I can print through Wifi but I can't get the scanner to work. I can scan from my cell phone though. I have the 24H2 os build 26100.2454 and I have the imageclass MF654Cdw laser all in one printer. I was disappointed because I just bought this from Best Buy and when I called tech support the automated system said I could not get live help for my purchase.

For what it is worth, I am finding that when the driver for the scanner is installed on Windows 11 if you look at device manager the device is disabled. Enabling it doesn't seem to change anything, but there is a message:

Driver Management has concluded the process to add Service StillCam for Device Instance ID ROOT\CANON_MF_NETWORK\0001 with the following status: 0.

What does that mean, because it seems to be the crux of the issue. The issue is absolutely with the driver not installing correctly.

I'm also having this problem. Just set up a brand new Win11 laptop and install the mf634cdw drivers and MF Scan Utility. Also on Win11 24H2 (26100.2314). Tried all the usual things - remove and reinstall, firewall, sfc /scannow

This is ridiculous. I'm disappointed in Canon. Actually, just read tjfitz68's comment above. Looks like it's Microsoft's fault, again... I knew win11 was going to be a hassle.

Canon has great printer. I think their developer don't spend time in putting in working to developed a good printer driver. All the drivers for their printer is very bad, they will put out bad driver and pretend like they don't know what is going on.

Once I updated my window 11 pc, now I got the printer ImageClasss MF462dw printing automatically 2 pages. Why should it be like that Canon? I didn't experience this issue with my HP or Epson Printers.

Someone from Canon will come here saying to uninstalled and reinstalled the driver, why should this be the fix? Do I have to do this every time I have to update my window 11 PC?

This's really bad for business. You guys are providing service and I believe it should be well prepared for the customers. No one buy Canon printer to go through Hardship.

CANON Please hired some good developer to produce good printer drivers.
