So as we all know, printer manufacturers are all land pirate criminals that will all go up against the wall when the peoples revolution comes.
Here is how to reset a #Brother Cartridge TN253M to full.
There is plenty of videos how to reset TN253 but not the #TN253M which is slightly different...
First and above all.
And I can not stress this enough.
NEVER EVER EVER NEVER Update your printer firmware. Unless it's chasing and eating your pets, the sole purpose of a printer firmware "upgrade" is to fuck you. If there are any hidden circumvention options.
The upgrade will fuck you and you can't roll it back.
See the little plastic tab on the photo? It is now in used up position.
After you refill the car-triage... or inherit a half full cartridge from another printer (in my case the fusor died on the office printer) $180 part on a $380 printer.
50,000 prints.
Fuck you very much.
Unscrew the two metal screws.
Gently lift the hood.
Move the T shaped piece so its at the bottom of the screw.
Put everything back together.
The little white nub in the aperature will be at the bottom "full" position and the printer will fuck it as soon as you put it in and will begin to use software counter.
There were literally no videos or pictures on the entire Interwebs how to reset the TN253M variant.

You are welcome.
