Removal and Replacement Strategy This chapter documents the removal and replacement of major assemblies. Replacement is generally the reverse of removal. Occasionally, directions for difficult or critical replacement procedures are included. WARNING! Unplug the power cord from the power outlet before attempting to service the printer. If this warning is not followed, severe injury may result. Never operate or service the printer with the protective cover removed from the Laser/Scanner assembly. The reflected beam, although invisible, can damage your eyes. This printer has some sharp sheet metal edges that can cause injury.
Electrostatic Discharge (ESD) Precautions CAUTION The printer and accessories contain parts that are sensitive to ESD. Always service printers at an ESD-protected workstation or wear an anti-static wrist wrap. Watch for the ESD reminder symbol on illustrations. 256 Chapter 6 Removal and Replacement C4265-90907
