Using the Front Panel LEDs for Troubleshooting
Over-Temperature
If the printer overheats, the Alert LED flashes and the
printer stops. Do not try to troubleshoot or adjust the printer—just allow it
enough time to cool down and it will resume operation on its own. You should
only encounter this problem after extended print jobs.
Media or System Faults
If the Empty/Pause or the Alert LED remains on, your
printer is experiencing a media or system fault. See Chapter 4,
“Troubleshooting,” for help in correcting the problem.
