imageCLASS MF656Cdw will not scan via a wireless connection

tommyboy39 — Tue, 29 Oct 2024 12:44:47 GMT

To save some time here and not have some of you ask me which printer, OS, etc, here they are:

Windows 11 Pro 24H2 with all current updates
Model of printer: Canon MF656Cdw
Any firewall blocks have been removed, granting the printer / scanner full privileges over the network
Printer firmware is up to date
Have tried to uninstall an reinstall software and drivers several times

First off, I bought this printer back in January or February of 2024. I installed it along with the programs just fine on a Windows 10 Pro PC. Printer and scanner worked via a wireless connection without issue. No firewall exceptions were necessary and I did not have to troubleshoot anything.

Fast forward 8 or 9 months. I built a new PC running Windows 11 Pro. Installed printer and scanner software. Scanner cannot communicate with the pc while trying to scan. The printer portion works just fine as I was able to print a test page. When trying to scan via the Canon MF Scan Utility (or any other software for that matter), I get the following message:

"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."

There is no cable as I use it via a wireless connection. Unless the printer came with a usb cable (I would have to check the box), I don't even have a cable to be able to print and scan via a usb cable. The printer and scanner are turned on. The scanner works as I printed a document directly from the scanner platen glass.

I'd like to know where to go from here. Why doesn't it work from my Windows 11 PC?

I have now reached out to Microsoft. They were not able to find any issues on the Windows end and suggested I reach out to Canon support.

Greetings,

I have a MF656Cdw connected wirelessly to our network. However, mine prints and scans without issue..

Can you please confirm the IP address of your printer?

I would suggest assigning a static IP for the printer on your router. Next uninstall the printer and drivers from your PC and restart.

Important. Install the device as an IP printer. If you are unsure what this is, let us know.

Run this first

[Windows 64bit] MF656Cdw/ MF654Cdw/ MF653Cdw/ MF652Cw MFDrivers (Generic Plus UFR II / Generic FAX / ScanGear)

And this one second

[Windows 32bit & 64bit] MF Scan Utility Ver.1.21.0.2

Thanks for replying.

I have the printer set with a static IP already.

I have uninstalled all software, restarted the PC, and then installed the canon drivers and software again on several occasions. It still cannot communicate with the scanner. I did it again just for the sake of it and the result was the same. The printer will work but the scanner will not work through the MF Scan Utility.

I installed Windows scan and the scanner works with that without issue. However, the Windows scan utility is about as basic as can be and requires extra work from me in a photo editor like photoshop. I like using the scanners native interface in advanced mode to preview the item I am scanning and then select the area I want scanned. I cannot do that with Windows scan. It scans it in letter size, legal, or A4 only.

Have any other suggestions as to why I can scan with other software and not the one that came with the actual printer?

Right behind you with the same problem @tommyboy39, same scenario including 24H2 except I am running an MF653Cdw flawlessly for over a year. Rebuilt the desktop (same HP Z2 hardware) due to a Windows Update issue and also upgraded to a larger SSD. Printer works fine, all other Canon utilities such as the toner status utility, scanner selector work fine as well. But ScanGear and Stitcher throw the same error as you've listed above.

I have also upgraded the firmware to v5.04, since it addressed several network vulnerability issues.

Please note; Windows Fax and Scan works with the scanner, no problem at all. But it might not be using the same method as the MF Scan Utility (i.e. Twain Driver vs WIA) not sure at this point.

I'll monitor your thread and offer any help where I can to get this resolved.

Sure hope we can figure this out. I can scan through Windows scan and Acrobat without issue. I just prefer that Canon native interface with more options over Windows scan when wanting to scan and save to an image file (jpeg, png, etc.). I know we are not the only ones as I have read some other forum threads as well. All I know is that, right now, Canon or any of the others offering suggestions here, can't provide more, other than stating to uninstall, restart and reinstall the drivers and other software. One of these days I will have to see if Canon offers any support through a chat interface on here as I really hate phone support, especially when it can be hard to understand some of these tech support folk over the phone. If I ever figure it out on my own (or if you do), we can add to this thread.

If it helps, I was working with another user who was running 24H2 and he's not having any problems (multiple systems), so the MF Scan Utility is compatible with W11 24H2. (v1.21.0.2).

@tommyboy39. In my first reply, I suggested that you uninstall the printer and driver, then restart. You may have done this, but it's not clear. Removing the printer is a separate step from uninstalling the software. Then restart.

3rd party anti--virus can also affect communication if you have this installed and running. This only applies to programs that are installed in addition to windows security. (mentioning if applicable)

After the printer is removed, the software is uninstalled and the system is restarted, I would suggest installing the printer as a TCP/IP printer. To ensure persistence and control assigning a static IP is recommended. (you confirmed this was done).

For install, I've done it both ways. You can install it using the Canon drivers specifying the IP, or from Advanced Properties and add it as a TCP/IP device. This method is buried in Windows 11. Desired outcome below. Mine uses 192.168.1.99

After you install the drivers, double click on the MF printer selector in the system tray. Ensure only one device is present and that is check boxes selected. Now open the MF Scan Utility and check the drop down (top right) corner.

You should see only one device. Now click the Scan Gear icon...what's the result?

If you continue to experience issues, run

>SFC /SCANNOW from an elevated command prompt. Does Windows report any integrity violations? If so, restart again and retest.

I have confirmation that the MF Scan Utility v1.21.0.2 runs under W11 24H2. These are the drivers used for install

[Windows 64bit] MF656Cdw/ MF654Cdw/ MF653Cdw/ MF652Cw MFDrivers (Generic Plus UFR II / Generic FAX / ScanGear)

[Windows 32bit & 64bit] MF Scan Utility Ver.1.21.0.2

Hope this helps.

Hi @shadowsports, I followed your advice to @tommyboy39, to no success, but thank you for providing it as a possible solution. Hopefully, tommyboy39 will have better results.

Best

Fyi; I tried applying KB5045934, the Cumulative Preview Update to 24H2, released on Oct 24th - but also, no luck.

Re: imageCLASS MF656Cdw will not scan via a wireless connection

tommyboy39 — Thu, 07 Nov 2024 16:27:00 GMT

Thanks again.

Yes, I removed the printer and uninstalled the drivers and software. Computer was restarted and the printer, drivers and software were reinstalled. Printer was attached to a static ip port. Scan utility shows only one device. Result: Cannot communicate with the scanner.

Uninstalled my 3rd party antivirus and utility program. Result: Cannot communicate with the scanner.

Reinstalled my 3rd party antivirus and utility program. Result: Cannot communicate with the scanner.

Ran sfc /scannow. Result: no integrity violations and still cannot communicate with the scanner.

Windows scan works in all situations mentioned above.

I did not have to do any of this when I installed this printer/scanner under Windows 10. It just worked.

I have the exact same issue as you. And I tried all ways in the above replies, but no lucky. Still doesn't work.

I'm having the same issue with my MF743CDW. My PC is running Windows 11 24h2 with a fresh install of Windows and just the canon printer driver/scan utility. When I try to scan from the utility I get the same error. I have a Windows laptop with 23h2 installed on it and it works fine. I ran wireshark on the PC and determined that the software isn't even attempting to contact the printer when you run the scan utility and receive the error.

I have the following versions of the software installed

MF741CMFDriverV6404WP

winmfscanutilityv12102

tommyboy39 — Thu, 07 Nov 2024 19:17:48 GMT

That's interesting @jjs710. It's working on a 23H2 installation but not a 24H2 installation for you. I have never heard of Wireshark. I installed it. What exactly am I looking for to make such a determination?

Re: imageCLASS MF656Cdw will not scan via a wireless connection

jjs710 — Sun, 10 Nov 2024 01:36:09 GMT

If you have wireshark installed and running you will need to search for all traffic between the printer IP and the computer IP. Normally you would set a capture filter like host 10.17.1.132 && host 10.17.1.199 Those two IPs are the computer and the printer. Then wireshark will only show you traffic between those two devices. When you click scan in the MF Scan Utility you should see traffic going between those IPs

Hello, I have a similar issue with the Canon MF443dw printer. The printer is connected via LAN, and two computers running fresh installations of Windows 24H2 with the latest updates are experiencing problems. The printer itself works fine, but MF ScanGear displays a communication error.

On other computers running Windows 23H2, everything works perfectly. I have tried reinstalling the drivers from the official Canon website multiple times, and I confirmed that the scanner selector is checked.

If I attempt to scan using the Scan Utility on the computer, ScanGear shows a communication problem error. The same issue occurs when I try to initiate a scan from the printer: the printer detects the computer, but when I attempt to scan, I receive a communication error on the computer side regarding ScanGear.

I am experiencing the same issue. In our office, we have hundreds of Canon MF443dw, Canon MF453, and other MFP printers. After the Windows 24H2 update, all of them have developed a problem when scanning over the network. I tried uninstalling and reinstalling drivers, updating printer firmware, and other troubleshooting steps, but unfortunately, nothing helped. Everything works fine on Windows 11 23H2 and Windows 10; the issue is specifically with Windows 24H2.

Re: imageCLASS MF656Cdw will not scan via a wireless connection

tommyboy39 — Mon, 11 Nov 2024 18:08:29 GMT

I'm kind of curious about the confirmation that it runs on Windows 11 24H2. With whom did you get confirmation from? Seems there are quite a few of us who are having the same issue so it is not an isolated event.

Re: imageCLASS MF656Cdw will not scan via a wireless connection

Luvbird — Thu, 21 Nov 2024 21:04:26 GMT

I have been working on this issue for two weeks. The issue is that Canon needs to fix the drivers for Windows 11 24H2. It works with previous versions. I just hope Canon will tell us when it is fixed. I used a work around by using Microsoft's Scan software built into Windows 11. As of 11/21/24, Canon still has not fixed the issue. One test to find out if this is the issue is to type in the search bar wiaacmgr. A window will pop up. If it shows "No friendly name", Canon still has not fixed the driver issue.
