Question about Brother MFC 7420 All-In-One Laser Printer
We recently replaced the drum and toner cartridge and everything that prints has lines and blotches on it. I don't know what caused this. It didn't happen immediately after replacing the drum and cartridge, several weeks later. Any help would be appreciated. Thanks Jeff
Did you clean the corona wire when you replaced them? Even with the Drum being brand new, you still need to run the little piece of blue plastic back and forth across the wire that is called the corona wire. If you don't know where that is, and do not have the complete software for your printer - you can find that at the link I have provided below. The short version is that it is just in front of the toner cartridge on the drum housing. If you do have the software, open the user manual and look for the table of contents listing that refers to replacing toner and drum cartridges. This will show you a picture of where the corona wire is.
