TROUBLE SHOOTING GUIDE
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.
