Why does my Mini Printer light turn green and then red?

If the light turns green briefly and then red, please try these steps:

1. Open the paper compartment.
2. Remove the paper roll.
3. Place the paper roll back inside correctly.
4. Leave a small amount of paper sticking out through the opening.
5. Close the paper compartment completely.
6. Press and hold the Power button for about 3 seconds.
7. Check if the light stays green.

If the light still turns green and then red after trying this again, please contact us and send a short video showing the printer and what happens when you press the Power button.
