Did you know that you can learn more about a problem experienced with the printer, by simply checking the LED lights?

In this Wiki article we show a few examples of how the LEDs behave when the printer is in a normal state with everything working.

It’s a good idea to check the LED lights if you encounter a problem, as it can help isolate the issue quicker

Nice, but what can the LEDs tell us about abnormal states? Do they just turn off, or flash an error code, or blink differently, or…?

For me the videos in the sections:
For the X1 series:

Normal State: the TH board indicator light is constantly red

Normal State: the MC board flashes red once every 5 seconds

these videos don’t appear correctly on the web page.

Normal State: the AP board has 2 indicator lights, one is constantly red, and the other flashes red once per second

This one works fine.

If the LEDs are not as shown in the videos and the printer is not working as expected, it is recommended to share a video with the Customer Support team so they can further investigate the issue by also checking the log files.

More information is also provided in this Wiki article: Printer Circuit Failure Troubleshooting - X1 Series
