Safety Instructions
Before installing and using the printer, please read the following items carefully.
ØSafety 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 reasons of safety.
The print head is an ESD-sensitive device. To prevent damage, do not touch either its printing parts
or connecting parts.
ØCaution
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 roller will be damaged;
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 quality is acceptable. This will help to
keep the print head durable;
14) Avoid turning on and off the printer frequently while using. Every time after turning off the printer, wait
at least 2s before turning it on again.
15) Do not disassemble the printer without permission of a technician, even for repairing purpose;
16) Keep this manual safe and at hand for reference purpose.
