Troubleshooting

If you have any problems as you set up and use your computer,

refer to this chapter. You can correct most problems by

adjusting a cable connection, repeating a software procedure, or

resetting the computer.

The troubleshooting suggestions in this chapter are organized

in general categories, such as “The computer will not start.”

Within each category, a more specific problem is described with

possible solutions.

If the suggestions here do not solve the problem, contact your

Epson service representative or Epson Direct.

ldentifying 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,
