Question about Brother MFC-9420CN All-In-One Laser Printer
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?
Since this machine takes TN04 cartridges, and there are no chips or anything, do a reset.From memory press 1 and 7 together, then 1.

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.
