This test verifies the control panel display function.
To run the Panel test:

2 Press X to exit the test.
Button Test
This test verifies the control panel button function except for the Sleep button.

2 The panel displays Press and an icon matching one of the control panel buttons. Press the physical button that is
represented by the icon, and the printer tests the function of that button.
If the test is successful, then the panel displays another icon to test.
If a button fails the test, or if a different button is pressed, then the panel displays Test Failed and returns to
the main section of the Hardware tests menu. After three seconds of inactivity, the panel automatically returns to
the main section of the Hardware tests menu.
If all buttons pass the test, then the panel displays PASSED and returns to the main section of the Hardware tests
menu.
3 Press X to exit the test.

maximum pass count being 999,999.
