There might be an issue with the metal contacts on the bottom left side of the drum. If the contacts are placed right then it will continue with the drum error. See the link for the location of the contacts. Try cleaning them on the drum and on the printer and see if that works.

Printer is back and white, print is faded, toner is fine. What could the problem be?


Most likely it is an issue with the Drum Unit.

Start by cleaning the Corona Wire. There will be a slider on the top of the Drum Unit. Slide it all the way to the other side and back to where the arrows meet and try your print again.
If this does not fix the problem replace the drum unit as the drum itself may be worn. The drums are rated to do 12,000 pages and it has probably done this. 12,000 pages equates to about 5-6 cartridges.

the drum will just need to be replaced im not sure if the toner and drum both come as one cartridge. But if not wherever you get your toner from, just ask for a drum cartridge. they are very easy to change.

How to remove a brother mfc-7440n drum???


When you replace the toner cartridge on the unit, you pull out the drum with the cartridge, and then snap the new toner cartridge back in. The assembly that the toner snaps into is the drum, if you flip it over it has a large black roller which wears out over time.
