3. Multi-colored LED indicator function

The multi-colored LED indicator will display red, green, and orange, with the specific functions as follows:

| Green indicates a status other than those mentioned above (such as print, warming up, sleep, ready, etc.).

6.3. LED Indications

The source of a failure can be determined by the LEDs' indication in the event of a failure.

The meanings of the status indication of the LED indicators are as follows:

No. | Status | Status Description
