How to judge whether is hardware failures in the printer?

The steps to print a self-check page are as follows:

1. Disconnect the USB connection and load paper
2. Wait for the green light to turn on (if there is no green light, please do the automatic label identification), press the FEED button and hold it down, release it after hearing two beeps.

3. It will print out the self-check label. If the self-test label prints well, the printer hardware is normal.
