The fuser melts the toner on the paper making the toner permanently adhere to the paper. Your fuser may need to be replaced when you get streaks on your printouts or if the toner is not adhering to the paper. Most Oki fusers are replaceable by the end user and are considered a consumable item.
If you need the part number for your Oki fuser, check our part diagrams for the Okidata part number. For directions on installing your Okidata fuser, you can get a free service manual.
