General Notes on Disassembly Preparation Before you begin any removal and replacement procedure: 1. Switch OFF the printer power and disconnect the power cord from the wall outlet. 2. Remove the Imaging Unit and protect it from exposure to light by covering it with a light proof bag or by placing it in a light-tight container. Disconnect all computer interface cables from the printer. 3. Wear an electrostatic discharge wrist strap to help prevent damage to the sensitive electronics of the printer circuit boards. 4. Remove the Fuser Assembly or wait at least 5 minutes after you have switched OFF printer power for the Fuser to cool before you work on or around the Fuser. Note Names of parts that appear in the removal and replacement procedures may not be exactly the same as the names that appear in the Parts List. For example; a part called the Registration Chute Assembly in a removal procedure may appear on the Parts List as Assembly, Chute REGI. When working on a removal and replacement procedure, ignore any prerequisite procedure if you have already removed that part. Caution Many parts are secured by plastic tabs DO NOT over Flex or force these parts. Do not over torque the screws threaded into plastic parts. Always use the correct type and size screw. Using the wrong screw can damage tapped holes. Do not use excessive force to remove or install either a screw or a printer part. Warning Unplug the AC power cord from the wall outlet before removing any printer part.
