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, the printer is
experiencing a media or system fault. See Chapter 4,
“Troubleshooting the Printer,” for help in correcting the problem.
