Question about Brother MFC 7420 All-In-One Laser Printer
Have a Brother MFC-7420. When I scan, there is a solid black line down the document about 2 inches from the right margin. I've cleaned everything and can't get rid of it.
Are you using the autofeeder to feed your documents?
if yes, open the top cover and clean both glasses (big and small).
and take the drum out, move the blue panel to clean up your drum.
after that should be working fine.
