printer shell, more particularly note protecting the printing head.

1. If the printer is not used for a long time, we do not turn on the printer power.

2. If the printer is not working properly, please turn off the printer's power.

3. Power supply must meet the requirements, or it is unfavorable for the printing head, and even

damages the printing head.

4. When replacing the paper roll, please note whether there are the paper scraps and dust on the

printing head. If having paper scraps and dust, please gently remove. Note the thermal paper's
obverse and reverse side, and if the reverse side is uncoated, the printer can‘t print out the
handwriting.

5. When the printer is printing or paper feeding, we can't tear the paper, and can't more reversely

drag the paper

6. Keep the printer control panel clean

7. When thermal printer prints unclearly, we can use the clean cotton ball soaked some alcohol to

gently wipe the surface dirt on the print head chip heating element.

8. When we connect the printer to the host, we should connect the printer data cable, and then

power on the printer.

9. To choose a good quality paper when we select the paper for the thermal printer can not only

improve the printing quality, but also reduce the abrasion for thermal film.
