MF 451 - scan to computer not working.


The scan to computer always shows up an error. The scan to file is working.

Also how do I turn on two sided scans to file from the printer?



Hi, asinghvi!

So that the Community can help you better, we need to know exactly which operating system is running on your computer (i.e. Windows or macOS, and which version thereof). That, and any other details you'd like to give will help the Community better understand your issue!

If this is a time-sensitive matter, click HERE search our knowledge base or find additional support options HERE.

Thanks and have a great day!


It was windows 10. The scan to computer is now working. However I still cannot enable 2 sided scan to computer.

Hello Asinghvi,

You can adjust the scanner settings for the MF451 using the MF scan utility that installs onto the computer along with the drivers. You will find the Utility in your list of installed programs under Canon Utilities. Once you open the scan utility, you can click the settings option in the lower right to access the settings. You can adjust the settings for the scan utility and the scan options that are on the operation panel using the information found at the link HERE.
