Hi vasudevan.


I will be able to assist you.


Please verify that the MF227dw is selected for network scanning by following the instructions below:

  1. Select [Applications] under [GO].

  2. Select [Canon MF Utilities] > [MF Toolbox 4.9].

  3. You may receive an error that the scanner is not connected. This is fine.

  4. Click [MF Toolbox] next to the Apple icon in the left corner of the screen and select [Network Settings].

  5. Select the [MF220 Series], and then click on the [+] symbol and select [Add].

Next, quit the MF Toolbox, and then open it back up.  Once the program is open, please scan a document and verify if you still receive an error.


If you still continue to experience an error, please call us at 1-800-OK-CANON (1-800-652-2666) for further assistance.
