The steps to print a self-check page are as follows:
①Disconnect the USB connection and load paper
②Wait 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
③It will print out the self-check label. If the self-test label prints well, the printer hardware is normal.
The self-test page can be used to determine whether the machine has a hardware failure.
