Precautions
This section includes information about how to safely operate and service the E-25C and how to avoid
damage to E-25C components.
Report shipping damage
If there is evidence of shipping damage, save the shipping boxes and damaged parts. Call the shipper
immediately to file a claim and notify your authorized service/support center.
Handling boards
When handling a printed circuit board, do not bend it. Hold it by opposing edges, rather than by the
corners.
Handling the HDD
To ensure that you do not damage the HDD, do the following:

Follow electrostatic discharge (ESD) precautions.

Keep magnets and magnetic-sensitive objects away from the HDD.

Do not loosen or remove the screws on the top of the HDD. Doing so voids the warranty.

Handle the HDD by its sides and avoid touching the printed circuit board.

Do not drop, jar, or bump the HDD.

Before you remove or install an HDD, allow it to reach room temperature.
Avoid magnets
Keep magnets and magnetic-sensitive objects away from electronic components, especially the HDD.
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 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
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
