INTRODUCTION 12
• Do not loosen or remove the screws on the top of the hard disk drive. Doing so voids the
warranty.
• Handle the hard disk drive by its sides and avoid touching the printed circuit board.
• Do not drop, jar, or bump the hard disk drive.
• Before you remove or install a hard disk drive, allow it to reach room temperature.
Avoid magnets
Keep magnets and magnetic-sensitive objects away from electronic components, especially the
hard disk drive.
Avoid fan blades
The E-43A contains hazardous moving parts. When servicing the E-43A, keep away from
moving fan blades.
Use caution with sharp edges
The edges of some E-43A components are sharp.
Electrostatic discharge
When you work with electronic components, electrostatic discharge is a concern since it can
destroy circuits, or damage them, reducing their life span. The area around the copier/printer
is most likely not static-free, and electrostatic discharge could occur.
Do the following to avoid damage due to electrostatic discharge:
• Work on a grounded antistatic mat.
• Wear an antistatic wristband, attached to the same location as the antistatic mat.
• Before you remove an electronic component from the shipping box, touch a metal area
of the copier/printer to discharge static from your body.
• After you remove an electronic component from the shipping box, place it face up on a
grounded antistatic surface.
• Leave electronic components in antistatic bags until you are ready to use them.
• Do not walk on carpet or vinyl while carrying an electronic component, unless it is in an
antistatic bag.
• If you remove an electronic component from the copier/printer, immediately place it in an
antistatic bag.
The power cable
Observe the following guidelines:
• Only use the power cable that shipped with the E-43A or an appropriate replacement
power cable. For replacement parts, see your authorized service support center.
• Before you open the E-43A, unplug the E-43A.
