Hello, if you encounter a situation where the printer is fully charged but cannot print, please follow these steps to troubleshoot:
1. Turn off the device and charge it. Confirm whether the device is fully charged. The full charge indicator light is a green light that is always on;
2. After confirming that the device is fully charged, check if the device can be turned on normally and remain on. If not, the machine is malfunctioning. Please contact after-sales service for assistance;
3. If the device can be turned on normally, confirm whether the printing paper is thermal paper. If the printing paper is not made of thermosensitive material, it will not be able to print;
If the above steps do not resolve the issue, please try the following:
1. Use the accompanying paper. If the printout is blank, this may be caused by the printing paper not being installed correctly. Try placing the printing paper upside down;
2. You can try replacing it with official consumables for testing;
3.If the above solutions do not resolve the issue, it is likely a problem with the machine itself.
