For this check, the program writes specific data into memory and

then reads it back. The data is written and read in blocks of 64KB. A
parity check is also made on each block. A memory count displays

after each block tests without error. After the program checks the last

block, you see a message such as the following:

If an error occurs, make a copy or a printout of the error code and
message, and contact your Epson dealer or service center. Attempting

to correct memory errors yourself may violate your warranty

agreement.

Use this option to check the operation and the configuration of the

keyboard. The program first checks the keyboard controller; during

this check, you see the green indicator lights on the keyboard flash.

Before checking the operation of the keys, you must identify your

keyboard layout so the test is appropriate for the keys on your
keyboard. A display appears, asking you to identify the shape of your

Enter 

key. Choose the shape that matches your system, then press

Enter. 

You can exit the keyboard test by pressing 0 and 

Enter.

The program displays your keyboard layout on the screen. When you
press a key on the keyboard, an asterisk appears at the corresponding

location on the keyboard layout. If you hold a key down, the asterisk
begins to blink. If an asterisk does not appear at the correct location,
there is a problem with your keyboard. Test each key.
