1. The printer only delivers paper without printing contents.
(1) Check if the print paper is reversely laid. If not, double click “On/Off button”to
print the self-test page.
(2) If the self-test page cannot be printed, the printer is malfunctioning. If the self-test
page is correct, check the paper or APP.
2. Blurry printing
(1) Check the print density whose default value is 3 for the best printing effect.
(2) If the prints have a horizontal line or only some of contents can be printed, check
if the print head is clogged and clean it with alcohol.
(3) If the print quality is poor, please use NiiMbot paper range.
3 Paper feeding or printing job cannot be stopped until 200mm paper
is delivered with the failure of paper positioning.
If no paper gap is detected after 200 mm paper is delivered, there are three
possibilities as follows:
Please confirm the correct type of label is chosen in the App. The printer
supports “Crack label”“Black mark label”and “Continuous label”.
2)When the cracking noise arises, the printer paper is used up. Please refill.

close it before restarting. If the problem persists, the printer is malfunctioning.
