Computer problems can be caused by software, hardware, or both. You can diagnose and solve many problems with the assistance of the self-tests and system programs contained in Easy-Setup. If a hardware problem is detected by the self-tests, an error message is displayed.
The system programs can identify a problem or provide information for the service representative. Make a note of all error codes and give them to the service representative when you call for service. If the system programs cannot be loaded, the troubleshooting charts and other information will help you determine what corrective action to take.
