Epson LT - 286e Selecting Diagnostics Tests

Selecting Diagnostics Tests

This section describes the various ways you can select the tests you want to run.

To start a single test, move the cursor to highlight the test category on the main menu. Then move the cursor to the submenu and highlight the test you want to perform. Press Enter to start the test.

To select several tests at one time, move the cursor to each test you want to perform and press F3. If you decide you do not want to run a selected test, highlight the test name and press F3 again.

You can press F4 to select all tests for all devices, and press F5 to deselect all selected tests.

Once you select a test, it remains selected until you deselect it. If you run a test or a group of tests and start testing again, DIAG performs the same tests unless you deselect them.

You must enter certain parameters for the hard disk drive and the diskette drive tests. If you use F3 to select these tests, DIAG prompts you for the information. If you use F4 to select these tests, DIAG prompts you for the information during the first pass of the test. If you perform more than one pass of the test, DIAG uses the same parameters for each pass.
