Question about Brother MFC 420CN All-In-One InkJet Printer
The diffuser is the optical lamp that distributes the light which allows the image to be seen by the drum and consequently put onto the paper. Is is not something you install. If you get this message , it it a mechanical problem and it needs to be serviced.
If I could be of further assistance, let me know. If this helps or solves the issue, please RATE it.
