General Safety Information
Before installing and using the printer, please read the following items carefully.
1. Safety instructions
Warning: Do not touch the cutter of the printer.
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.
Warning: The print head is an ESD-sensitive device. To avoid damage, do not touch either its
printing parts or connecting parts.
2. Caution
1)
Install the printer on a flat and stable place.
2)
Reserve adequate space around the printer so that convenient operation and maintenance can be
performed.
3)
Keep the printer away from water source.
4)

direct sunlight.
5)
Do not place the printer on a place exposed to vibration or impact.
6)
No dew condensation is allowed to the printer. In case of such condensation, do not turn on the
power until it has completely evaporated.
7)
Connect the DC adapter to an appropriate grounding outlet. Avoid sharing a single electrical with
large power motors and other devices that may cause the fluctuation in voltage.
8)
Disconnect the DC adapter when the printer is not used for a long time.
9)
Don’t spill water or other materials on the printer. If 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
