Question about Brother MFC 7420 All-In-One Laser Printer
I am experiencing black copies emerging from this machine. I was told by a Brother tech to change the drum. Drum was changed and the problem is still ocurring.
What can I do?
Check your owner's manual, and there's one in the install disk. It will show you where there are electric contacts inside where the drum is. You may have to take the drum out to see them. You're supposed to clean them with isopropyl alcohol on a q-tip. Don't get alcohol on anything else.
