Please remove the label paper first, then close the printer cover and turn off the printer. (Do not put any printing paper in the printer)
Please press and hold the printer feed button, and then turn on the printer power at the same time. (While pressing and holding the feed button, turn on the printer)
After the red light flashes three times, release the feed button. The printer will automatically flash purple light and restart.
After the printer automatically restarts, the red light starts flashing. Now you can install the label paper on the printer. The printer will automatically feed and calibrate the paper. After the paper feeding is completed, the indicator light will turn back to a fixed blue light.
(No need to manually run the label automatic recognition process again, you can use the printer directly)
