   Hardware Tests >Panel Test
2. Press ✖ 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 ✖ or Back to exit the test.

DRAM Test

This test checks the validity of DRAM, both standard and optional. The test repeatedly writes patterns of data to the DRAM to verify that each bit in the memory can be set and read correctly.

To run the DRAM test:

1. From the Diagnostics menu, navigate to:
   Hardware Tests >DRAM Test
2. Testing… appears, followed by Resetting the Printer.
3. After the printer resets, the results of the test appear: DRAM Test [x] P:###### F:######.
   - [x]—Represents the size of the installed DRAM.
   - P:######—Represents the number of times the memory test has passed and finished successfully, with the maximum pass count being 999,999.
   - F:#####—Represents the number of times the memory test has failed and finished with errors, with the maximum fail count being 999,999.
4. After the maximum pass count or fail count is reached, or when all the DRAM has been tested, the test stops and the final results appear.
