I have changed all the ink cartridges on my Brother MFC5440CN it

That sounds like maybe a printer cartridge problem. Perhaps the ink flow is not working properly.

I have a brother MFC 3240C. My Black ink stopped printing(initially printed horizontal faded lines and gradually got worse), the other colors were printing fine. I tried cleaning numerous time( 50 -100 times over 1-2 weeks ). Still no improvement. The way I print now is:
1. I go to Printer Properties
2. Change Media type from "Plain Paper" to "Inkjet Paper".
3. Change Quality to "Photo".

This takes a long time to print 1-2 minutes per page. However, this works for me since this is my Home printer and use it for printing only few pages here are there.

Good Luck

You may need to replace the toner cartridge or replace the transfer roller, I believe that's what it's called. It's the roller that transfers the ink from the toner cartridge to the paper.

Light/faint prints usually are a result from clogged ink or air bubbles between the cartridge and print head (thus changing cartridge wont fix problem). Try printing the test page print from the machine (Ink Management -> set/ok twice). Answer the question(s) in the display and repeat this up to five times. The colors should be improved after 1-3 test prints usually.

Print head will have to be replaced. Whenever one or more colors won't print and you've gone through the cleaning process, the printhead is bad!

You need to clean the nozzle of the ink cartridge. If this does not work, you need to replace the cartridge.

Your printer have 4 sensors for ink level in ink tank section. Clean this sensors. Incorrect or dust colors - problems with printhead, or with the ink system. If you never replace printhead on this printer - call service. Thats be cheepest.

The print heads don't appreciate being out of ink so the Brother printer has sensors to prevent that but the tape defeated that prevention. Maybe more cleanings or maybe a cartridge with printhead cleaning solution will help. Otherwise, I fear a new printer.
