Replace new toner and displeyd mesages "chesk waste toner box". i remove waste toner box and cleaned waste toner in drum unit. no result...

On most color machines emptying the waste toner cartridge isn't an issue because the auger system dumps it into the waste toner. The brother machines before this a different way and have a cleaning blade in them. This blade wears out over time and needs to be replaced. Those waste toners last forever in that machine so your better off just replacing it. Other wise you probably are going to make a huge mess just to have problems once you get it back together.

by replacing the drum... hence prepare new drum

Open top and front cover and remove Developer Unit. Next, open the left cover (at the waste toner box), remove waste toner box. Unlock the drum unit lock and then remove the drum unit. If the printer is dirty inside, clean it with vaccum cleaner. Be carefull with the drum surface, not to scratch it. Put the Drum Unit into a dark place if you remove the unit for a longer period of time. After you cleaned the printer inside, put the Drum Unit back. Dont forget to push the unit firmly, for good electrical contact. Put all the other components back and turn on the printer.

You will need to replace the waste toner box on the Brother HL-4040CN. You can order the replacement from http://www.brothermall.com/Accessories/AccessoryDetail.aspx?AccessID=WT100CL&Model=HL4040CN&AspxAutoDetectCookieSupport=1 or your local supplier.

To replace the toner box, turn off the printer and open the front cover. Then remove the drum unit. Place the drum unit on a flat surface covered with newspaper or something else disposable to contain any loose toner. Then remove the belt unit carefully. (Hold the green parts and pull it up and then out.) Again place the belt on newspaper in case there is loose toner.

Now you can remove the waste toner box. Pull it out by the green handle. Discard of this properly.

Then put in the new waste toner box (by the green handle). Return the belt unit to the printer (line up the down arrow on the belt unit with the up arrow on the printer). Push it in and then push down on the green areas until it locks. Then replace the drum unit. (Make sure the grey lever is up when you start and then push it down to lock in the drum.) Line up the green guides on the drum unit with the green arrows on the printer. Close the printer and turn it on.

Hi there you can empty the waste toner box wich is located inside drum unit.

The procedure is next:

open front cover and leftsideway door
release the blue handle above the drum unit
pull out the drum unit
on top of drum unit, near handle is located plastic grey colored cork
remove it and by means of vacume cleaner clean the vaste toner.

Note that if you flip out the drum unit and try to empty waste toner it could be messy and the toner can get into charge roller or on drum cleaning blade and then you need to change it completly.

I posted this on another solve problem previously, worth looking at.

Remove the developer and toner cartridge from the front of your unit. This will allow you to take out your drum where your waste toner box is. Once you have your drum with your waste toner box make sure to detach the waste toner box from the drum. Take a damp linen free cloth and wipe down the inside of the drum unit where your waste toner box goes in. Now take your waste toner box and make sure to secure the waste toner box really well to the drum. This has to be in very tight or else the printer will not think that there is a toner box attached the drum and this error will continue to appear. Important thing is to make sure that the toner box is attached really well to the drum unit.
