Troubleshooting

Refer to this chapter if you encounter any difficulties as you set

up and use your computer. If the suggestions here do not solve

the problem, perform the steps below to identify your system

and note any error messages your computer displays. Then

contact the Epson Connection at (800) 922-8911 for assistance.

Identifying Your System

When you request technical assistance, be ready to provide

the serial number of your computer, its system BIOS version

number, its configuration (including the type of disk drives,

monitor, and option cards), and the names and version

numbers of any software programs you are using.

You can find the computer’s serial number on its back panel. If

you are able to use your computer, follow the steps below to

obtain information about your configuration, as well as the

version numbers of your system BIOS and MS-DOS (or other

operating system).

1. Turn on your computer or press to reset

it.

2. As the computer performs its power-on diagnostics, the

version number of your video BIOS appears at the top of

the screen. Next, the system BIOS version number appears

in a window at the bottom of the screen. Quickly write

down these version numbers. If you do not have enough

time to do this, press and try again.
