I refilled the black cartridge on my Borther MFC9420CN printer. It worked great for awhile. But all of a sudden one day it stopped printing and gave an error code (Toner Error-Incompatible toner detected).
When I removed the cartridges, black toner was everywhere. The cap was very loose when I replaced it, and it had fallen into the cartridge.I fished it out and reseated it.
I have rebooted, taken the cartridges out. I continue to get the same error.
I called Brother and they told me to replace the cartidge. Those things cost $169. That is why I refilled it in the first place.
My best guess is that there is a preset on the cartridge, or on the machine, that will allow only a certain number of prints per cartridge so that the Brother Cartridge Mafia can extort more money out of people by making them throw away a perfectly good cartridge.
Can anyone tell me how to get around buying a new cartridge?
Ok i hit 1& 7 at the same time and pressed 1 to reset opc belt, then i hit 2 and 8 at the same time and pressed 1 to reset fuser. i took each of the catridges out vacum cleaner them and then on the right side rotated the cylinder a few times to ensure they were locked as i notticed some toner being released. (did this for all toner cartridges). I then put them back in and the system reset and strated printing. I believe the later cleaning and rotatiing the cylinder of the catrridge did the trick. Hope this is helpful.

It is perfectly safe to cover the sensors on either side of the cartridge. What works best is to cover it with a piece of black electrical tape. The cartridge is set up so that when you put it in the printer, the printer shines a laser from one end of the cartridge to the other. This laser reads the toner level. If you cover both sides up with tape, it tricks the printer into thinking the cartridge is full of toner.
Yeah you can refill your cartridge. It is really easy and consists of removing the plug on the side of the cartridge, dumping out any old toner and dumping in the new toner. Its very easy. I have purchased refill kits from both of these sites in the past and its worked great:
They also have great customer service. I hope this helps!
The toner cartridge sounds like the problem to me. Did you refill it? Or have it done? It sounds like an incompatible brand......toner is very model specific, and not just 'any' will do, and it often doen't mix well with the remaining toner i the cartridge if it is not completely disassembled and cleaned out. Just curious
When the Toner Life End LED flips on, requires you to replace the cartridge,
even when there's still toner left in the cartridge. The machine
detects end of life by shining a light through from one side to the
other. To circumvent the detection mechanism, remove the cartridge and put
a piece of masking tape over or jam a little bit of paper into the clear opening/circle on the right side
of the toner cartridge, and then pop the cartridge back in. Eventually,
you'll start seeing streaks, and then you'll know that the cartridge is
if your brother machine is within warranty, give the tech support a call. if not,replace the black cartridge with a new one. it may be a defective cartridge that you have or if you are using refilled cartridges, it will also give the same problem
