If you print out a config page it should say Generic 35C-4, which is a C353. You probably have the "planets" screen when booting up the machine, too. This is an easy fix:

1. Access the Service Mode.
2. Select System 2.
3. Select Software Switch Setting.
4. Enter Switch No. "10".
5. Bin Assignment "00000000".
6. Hex Assignment "02".
7. Click on Fix.
8. Click on End.
9. Power the MFP OFF/ON.
10. Print another Configuration Page. Page Header should now be changed to Konica Minolta.
