This fuser assembly is a genuine Oki consumable item. The fuser is very easily installed by the operator. To remove your spent fuser from the machine first lift the blue locking lever, then grab the center handle and gently raise the fuser assembly straight up and out of the printer. Installation of your new fuser is just as simple. Take your new fuser and gently lower it directly into the printer. Lower the blue locking lever to lock the fuser into position. Turn your printer on and close the top lid and allow your fuser to come up to temperature.
