How to replace

It is the shiny green metallic cylinder in the bottom back of the printer. It is the last piece to come out when you remove the toner waste unit and then all the toners. It sits on the very bottom/back of the toner bay. They are not cheap but do not need to be replaced very often and it will give like new printing after.
