I have tried on three separate windows 11 machines. It is MF731CDW.
The printer cannot find my computer to scan too, and when using the MF utility,
I get the error
A scanner driver supporting this software is not installed. Install it and try again. 9,203,0.
I installed everything the same way I always do, and I have never had issues in the past. Complete driver package and then the scanner utility. Printing has always worked just fine.
Problems on Thinkpad, Surface pro 6 and my desktop computer. All the same thing.
The error would point to an issue with the scanner driver installation on the computer. If the driver is not currently loaded, the MF scanner selector will not be ale to connect to the scanner over the network. In that situation, you would not be able to scan from the computer or from the operation panel.
You can try installing the [Windows 64bit] MF733Cdw/MF731Cdw MFDrivers (Generic Plus UFR II / Generic FAX / ScanGear) from our support site while any security software is turned off on the computer. Once installed, you can try opening the MF scan utility to see if you get the same error.
If you continue to have issues with scanner driver, I would suggest contacting support at 1-800-652-2666. Our agents would be happy to check what is blocking the install on the computer or what might be causing the driver issue.
