The motor or gear driving your toner will be kaput. The nvm is just a datbase location that it refers to when it needs to know something. All that will do is run out your black developer (as no toner will be reaching it) Engineer is whats needed

How do I clean toner from machine?


Probably it's the jammed paper that might caused the error. I suggest have it serviced by the technician. Be aware of the paper handling capacity of your machine to minimize jamming:

System fault 9-363 i tried everything i know, please help


You can try this, try to clean the dev rotary sensor. open the upper right hand cover then there are two assy's to be removed also for you to access the rotary sensor located inboard side. this sensor senses the home position of rotary developer. to removed this sensor, you have to open the rear cover, then rotary pwb. some 9-363 code is due to busted fuse in the rotary pwb. Or could also be a fault with the fuses.

Why is there black line printed across the page in 3 different areas when something is printed. I changed the toner catridge.


This is nearly always the fault of the toner cartridge. The previous cartridge may have left toner on the transfer roller and this may have contaminated the new toner cartridge. Take the toner cartridge out and inside the printer under where the toner cartridge goes you will see a felt roller that goes across the printer and has a gear at one end. Wipe this roller with a dry clean lint free cloth, rotating it to make sure it is completly clean.
Check the blue coloured drum on the toner cartridge to see if there is a black line going across it. If so clean it with the same dry clean cloth.
If this does not work then I suggest you buy a genuine toner cartridge and try that.

Problem in color printing


I suggest making sure you installed them correctly, you can take them out and put them back in, it will ask you if you just replaced the cartridges one by one "select yes" if they are new, then try to print out a test sheet (which you do this through one of the options in your "menu" on the machine itself, it should be in your manual or you can look online in the Brother 240-MFC troubleshooting tips for printing, this just happened to me a few days ago and I got the answer there. So, when you print out the test sheet it will probably have colors missing and you say "NO' that it is NOT GOOD, and then it will do another cleaning and then print out another test sheet and hopefully it will work then, otherwise tell it NO again and have it do another cleaning, sometimes it does take a few times. This happened to me the other day when I replaced a black ink cartridge and I could not get ANYTHING TO PRINT, it kept coming out BLANK PAGES, so I went to the troubleshooting tips on the website and this was the advice I was given, it took THREE CLEANINGS and three test sheets before the black boxes printed out fully on the test sheet with none missing and ONLY THEN was I able to print successfully, GOOD LUCK TO YOU.

Magicolor 2400W error


This happens to me every few months, I have to do a VERY detailed cleaning of all toner sensors. The knowledgebase on KM's website is actually very good about walking you through which sensors to clean and pictures indicating where they are located. This has fixed me up every time. GOOD LUCK!
