My hl 4040cn says drum ends soon. do I have to

I have a similar problem now: magenta stain over the entire page when printing anything with any color (even just a hyperlink); B&W text is no problem.Not the PC; even the Demo Page from the 4040 menu does this. Updated the 4040 firmware tonight to latest (1.24, etc), but no better.Recently replaced the Magenta cartridge (official Brother cartridge), though saw this problem near end-of-life of the previous Magenta cartridge. Drum Unit status is 42%, so not expected to be near end-of-life.

1. When you replace the drum unit with a new one, or just want to extend the life of your existing drum unit, you need to reset the drum counter by completing the following steps:
   
   
2. Press the + or - button to choose "Machine Info".
3. Press OK to proceed to the next menu level, and then press the + or - button to choose
   "Reset Parts Life".
4. Press OK, and then press the + button to choose "Drum Unit".
5. Press OK two times.

Good Luck and Thank You for using Fixya.

first you are talking about the FUSER END message that means you have to change the FUSER and as for the DRUM and BELT you have to RESET the TIMER to tell the printer that it has been changed as well as for the FUSER those are consumable parts they have a life and the printer is programed to tell you to change them after so much copies.

Good luck!

This message will appear if the drum unit is near the end of its life. Use the drum unit until you have a print quality problem, then replace the drum unit with a new one

No this is something you can do yourself, its a consumable you need to purchase.

It can be purchased at any store that sells brother products.

The DRUM life is near to end . Replace the DRUM to solve the problem.

The instructions to reset the drum after changing are packed with the new drum, and the belt unit is the transfer belt that also wears out and needs changing periodically. The instructions are packed with that also and not hard to change.

You will need to replace the Drum unit with a new one.

To try to get it working for a short temporary fix, clean the Drum corona wire - might work, might not
