Safety Instructions
Before installing and using the printer, please read the following
items carefully.
1．Safety warning
The print head is a thermal element and it is at a high
temperature during printing or just after operation, therefore do
not touch it or its peripherals for safety’s sake.
The print head is an ESD-sensitive device. To prevent damage,
do not touch either its printing parts or connecting parts.
2．Notices
1) Install the printer on a flat and stable surface;
2) Reserve adequate space around the printer so that convenient
operation and maintenance can be performed;
3) Keep the printer far away from water source, and do not expose
the printer to direct sunlight, strong light and heat;
4) Do not use or store the printer in a place exposed to high
temperature, high humidity or serious pollution;
5) Do not place the printer in a place exposed to vibration or
impact;
6) No condensation is allowed to the printer. In case of such
condensation, do not turn on the power until it has completely
gone away;
7) Connect the printer power to an appropriate grounding outlet.
Avoid sharing one electrical outlet with large power motors or
other devices that may cause the fluctuation of voltage;

8) Disconnect the power when the printer is deemed to idle for a
long time;
9) Don’t spill water or other electric materials into the printer (e.g.
metal). In case this happens, turn off the power immediately;
10) Do not allow the printer to start printing when there is no
recording paper installed; otherwise the print head and platen

11) To ensure quality print and normal lifetime, use recommended
paper or its equivalent;
12) Shut down the printer when connecting or disconnecting
interfaces to avoid damages to control board;
13) Set the print darkness to a lower grade as long as the print
