Brother dcp 7020 says toner end life

I got the “toner end life” message on my Brother DCP 7020 printer-copier-scanner. I reset the white tab on the end of the cartridge and the message went away and the machine worked again! Here’s a little more detail on locating and resetting the tab. The white tab sits in a half-circle channel molded in one of the black plastic end caps on the cartridge. To reset it you have to unscrew three phillips head screws and pull the end cap away from the cartridge exposing a set of white plastic gears. The white tab is part of a larger plastic piece which has a short geared section. All of the other gears are attached to the body of the cartridge and do not come loose when the cap is taken off. The tab/gear piece, however, pivots on a post molded into the inside of the cap, and can be freely slid on and off this post. Once the cap is off it is easy to reposition the piece on the post, so the tab is at the opposite end of the circular channel. Holding the tab piece in this position put the end cap back on the end of the cartridge and its geared part meshes with the other gears. Screw the three screws back in, put the cartridge back in the machine, turn it on, and if your problem was my problem, it should be solved. None of the other solutions mentioned above worked for me. I can also confirm, as mentioned above, that the starter cartridge that came with the machine does not have the white tab piece, but does have the channel for it, apparently to make it impossible to add toner to the original cartridge.
