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 Print Cartridge and protect it from exposure to light by covering it with a light
proof bag or by placing it in a light-tight container.
3. Disconnect all computer interface cables from the printer.
4. Wear an electrostatic discharge wrist strap to help prevent damage to the sensitive
electronics of the printer circuit boards.
5. 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.
6. Tray 2 can interfere with the removal of many printer parts. Remove Tray 2 before further
disassembly.
Wherever this video icon appears throughout the manual, detailed
instructions for that procedure are available with videos on the
Phaser 3500 Product Training CD-ROM.
Note:
Part names that appear in the disassembly procedures may not exactly match the names
that appear in the Parts List. For example, a part called the Registration Transport Assembly
may appear on the Parts List as Assembly, Transport Regi.
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 either remove or install either a screw or a printer part.
A spring hook is required for removal and replacement of the various springs in the printer.
Springs can be damaged using pliers or other tools for this task.
Warning: Unplug the AC power cord from the wall outlet before removing any printer part.
