MF Scan utility not working on MF643CDW

Hello,

I just got a new laptop w/ Windows Home 11. I installed the driver and MF Scan Utility software. The printer prints just fine but it won't scan documents when connected via a USB cable or wirelessly. I get the standard error msg stating "Cannot communicate with scanner...... Cable may be disconnected......"

Please help with any known workarounds.

Thanks!

Hello Rovi639,

If you can print but can't scan, it will usually point to a setting issue or something blocking the scanner connection. In this situation, you can try turning off any security software and then trying a scan again to see if you get the same error. If you do, you can leave the security software off and you can try reinstalling the [Windows 64bit] MF643Cdw MFDrivers (Generic Plus UFR II / Generic Plus PCL6 / ScanGear) using the link HERE. The error you mention looks like the software is set to the USB connection so I would suggest trying the network option for the setup to see if it resolves the issue.

If you continue to have issues with scanning, I would suggest checking the Canon support site for your specific country for any additional support options. Unfortunately, the MF643 is not a US model and I would not have any support options for the printer.
