In the process of using the printer, if you come across the phenomenon of paper jam,
please stop printing in time and power off the printer. The paper jam is usually caused by
the failure of the automatic cutting cutter head to fully back into the body of the paper
cutter after the paper cutting.
When the phenomenon of paper jam occurs, it usually causes paper cover to be unable to
open normally. At this time, please do not forcibly open the cover to avoid damaging to the
printer.
The paper jam exclusion method is as follows:
1. Power off the printer and remove all connecting wires connected to the printer;
2. Pull out the paper cutter cover horizontally and forward as shown in image 4;
3. Rotate the cutter wheel with your finger to rewind the cutter head into the cutter body;
4. Press the "paper cover switch" button vertically downward to open the paper cover and
remove paper jam;
5. If the printing and paper out are normal, then reinstall the paper cutter cover.
