Basickly, Toner cartridge has two sides one side to refill the toner,
other side has two screws, this is the side you have to work on,,
A- Remove 2 screws,,Remove cover out (( SLOWLY )) do not loose ther Gear
or the Spring,,
B- Turn The Big white Gear Full Turn,
C-reinstall the gear back.
D-But back two screws,
Good Luck,, Some times you have to try it 3 or 4 Times,,
