COMPONENTS 25
TO CHECK INTERNAL CONNECTIONS
When you handle electronic components, follow standard electrostatic discharge (ESD)
precautions. For more information, see “Standard electrostatic discharge precautions” on
page 11.
1. Shut down and open the E100 (see page 14).
Make sure to remove the AC power cable from the power outlet before opening the E100.
2. Make sure that all E100 cables, devices, and the DIMM (dual in-line memory module) are
present, intact, properly aligned, and well-seated in their connectors.
Check the following for proper installation in the chassis: power supply, HDD, enclosed fan,
motherboard, and motherboard components.
Check motherboard cable and component connections:
Check all other power supply cable connections in the chassis.
3. If, after you verify connections, one or more E100 components is still not receiving power,
check the copier and its internal interface to the E100.
For more information, see the documentation that accompanies the copier.
