If the suggestions here do not solve the problem, perform the
steps below to identify your system and make a note of any
error messages your computer displays. Then contact your
Authorized Epson Servicer or call the Epson Connection at

Identifying Your System
When you request technical assistance, be ready to provide the
serial number of your computer, its ROM BIOS version
number, its configuration (including the types of disk drives
and options), and the names and version numbers of any
software programs you are using.
You can find the serial number on the underside of the
computer. If you are able to use your computer, follow these
steps to obtain information about your configuration, as well as
the version numbers of your system BIOS and MS-DOS:
1. Turn on your computer or press
to restart it.
2. As the computer performs its power-on diagnostics, it
displays the version number of your system BIOS as part of
the copyright information. Write down the number.
3. Write down any information about your setup shown on the
configuration screen that may help in identifying the
problem.
4. After the MS-DOS prompt appears, type
VER
and press
to display the MS-DOS version number. Write it down.
