The thing is he is not using the educational release, he is using a licensed one so this plot stamp should not be present in his drawing.  Quick research shows that the stamp is some kind of Autodesk bug (not sure about this but this is what I read from autocad forum & discussion).

What should he do then to remove the plot stamp “Produced by an Autodesk Educational Product“?

Follow these steps:

1. Open the affected drawing
2. Type dxfout in the command prompt
3. Save the dxf in the location you can easily access
4. Now, type dxfin in the command prompt
5. Browse the file you save in step 3
6. Save the file as dwg

The Produced by an Autodesk Educational Product should be removed upon completion of the steps above.  If the educational product plot stamp still appears, check the xref file and apply the steps I’ve mentioned above.
