Removing and Replacing the Fuser Assembly on the Dell 3000cn/3010cn/3100cn Laser Printer

I keep getting error code 010-397. I know it has something to do with the fuser, but every time I try and find documentation about how to remove and reseat the fuser, Dell sends me to https://www.dell.com/support/kbdoc/en-us/000151854, and I get this response: "The chosen document is not currently available. Please try again later." So anyone have documentation that might actually help me? THANKS
