2.Check paper size setting
Check if the paper size is set incorrectly. Setting the appropriate paper size that matches the paper size you are using is necessary.
3.Clean the Printer Head
Clean the Printer Head and paper sensor with 75% alcohol pads.
4.Close up the cover firmly
There are clips on both sides of the top cover that can be connected to the bottom of the printer. Make sure both sides are pressed and tightly engaged.
Press the top cover with both hands to close it and you will hear a click, which indicates that it is completely closed.
5. Run automatic label identification
For labels separated by gaps
Restart the printer, insert the label, and make sure the label is straight and smooth. While the printer is on standby (the indicator light should be blue), hold the Feed Button for about 3 seconds. Wait until the indicator light turns purple, then release the Feed Button.
For labels separated by black lines or marks
Insert the label and make sure it is straight and smooth. Turn off the printer. Then, hold the Feed Button while turning on the printer. Wait until the red light turns blue, then immediately release the Feed Button.
If the Labellife APP is not updated to the latest version, and the label you are using is a type of printing paper that is not available in the old version, it may also cause the actual printing paper to be inconsistent with the paper size and type set in the APP.
