Beacons Test
Run this test to illuminate all LED beacons on the printer. All beacons will remain illuminated in their solid “on” state
until the user presses Off. All beacons return to their previous state when the printer returns to normal mode, so if a
beacon was activated before entering Diagnostics mode, then it will be activated when in normal mode.
Note: This test is only available for MX81x models.
To run the test:

From the Diagnostics menu, navigate to:
HARDWARE TESTS > Button Test

Choose one of the following:
•
On—Illuminates all the LED beacons on the printer
•
Off—Turns off all the LED beacons on the printer

Press X or Back to exit the test.
DUPLEX TESTS
Quick Test
The Duplex quick test determines if the top margin at the back of a duplexed page is set correctly. This test prints a
duplexed version of the Quick test page that can be used to adjust the duplex top margin. Use either Letter or A4 paper.
To run the Duplex quick test:
1
From the Diagnostics menu, navigate to:
Duplex Tests > Quick Test
2
Choose any of the following:
•
Single—Prints a single Quick test page.
•
Continuous—Continuously prints the Quick test pages until X is pressed.
The printer attempts to print the Quick test page from the default paper source. If the default paper source supports
only envelopes, then the page is printed from Tray 1.
The Quick test page contains the following information:
•
Printer registration settings
•
Code levels

Alignment diamonds at the top, bottom, and each side
