Question about Brother MFC-L3770CDW
The printer smears or has strange marks on the side. Do I have to replace something after a certain time? If so, which part?
Did you move the green part back and forth when changing the toner?
If not, try that, otherwise replace the drums (they should last 20000 pages though).
