Really easy, open front door - there is little latch in the centre which you need to press, retrieve the tray - lift handle slightly up and then slide out, remove empty cartridge - lift it by the handle, at slight angle towards you, you do not need to change all cartridges at this same, only these which are empty.

reverse the procedure to insert new cartridge.

do not forget to empty or change waste toner!

i find actually this on brother site:

Printed pages have streaks vertically along edge

Sounds like the end seals in the cartridge are bad. Remove the cartridge and see if there is toner built un inside printer. Also look at the drum on the cartridge to see if it has black lines that line up with the pirnt defect you are seeing. Try a new toner cartridge and run about 50 pages through.

Can someone please help me i have just printed off 400 prints with my brother hl 4040CN laser printerits brand new and its now saying my cyan toner has ran out this is impossible i am right in the middle...

Your toner usage will depend upon how much of each color toner is used on each page. (To conserve colors when printing in Black and White only, specify monochrome in your printer setup) <div>I had similar problems when printing publicity flyers. The toner cartridges claim to be good for about 2000 prints each, but I was lucky to get 3 or 400 pages when printing blocks of color. The TN115 cartridges hold significantly more toner, and the cartridges that come with the printer are TINY.</div>

Brother HL-4040CN won't read or show new refilled cartridge in the LCD

I think I know what the problem is...
When you refill these toner cartridges you need to reset the "toner empty" cog wheel.
For instructions on how to do this follw this link:
It has pictures and explains how to reset the cartridge
Good luck,

HL-4040CN don't show or read new refilled magenta cartridge.

If you have removed and reinstalled the magenta cartridge several times, it is very likely the cartridge is defective out of the box. If you have another magenta cartridge, put that one in and see if the problem resolves. I'm betting it will. If that second cartridge does work, then return the defective cartridge to where you purchased it - they should replace it without a hassle.
