Question about Brother MFC-9840CDW Laser Printer
I have the same problem, first magenta said it needed to be replaced, then a couple of weeks later it asked for Black, I replaced the black the same way, and then also tried another new cartridge (both Re-manufactured) they have a security sticker on the side. Both didn't work so next I will try opening the side to see if the gear is reset or the optical sensor needs to be covered as when you add toner to an OEM cart. Strange that only the black seems to cause problems. The cost of toner and ink (for ink jets) is so cheap, yet if you figure it out by weight it costs much more than gold. Sometimes its just easier and more cost effictive to buy a new printer
