Entering the Diagnostics menu

The Diagnostics menu contains tests that are used to help isolate issues with the printer. To access some of these tests, avoid POST tests that run at POR. Some POST tests can generate errors that prevent a diagnostic test from running.

Do either of the following:

• To access the Diagnostics menu from the home screen, press * * 3 6 on the control panel. This method is preferable.
• To access the Diagnostics menu without running the POST tests:
  1 Press and hold the 3 and 6 buttons while turning on the printer.
  2 Release the buttons when the splash screen appears.
