Don»t touch the cutter of printer.
The printhead is calorific and its temperature is high when printing or just after operation, so please don»t
touch it and its peripherals for safety purpose.
The thermal head is an ESD-sensitive device. Don»t touch its printing part and connecting parts to keep it
from damages.
2. Caution
1) Install the printer on a flat and stable place.
2) Reserve adequate space around the printer so that the operation and maintenance can be performed conveni-
ently.
3) Keep the printer far away from water source.
4) Do not use or store the printer in a place exposed to heat of fire, moisture and serious pollution and do not ex-
pose the printer to direct sunlight, strong light and heater.
5) Do not place the printer on a place exposed to vibration and 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 gone away.
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 of voltage.
8) Disconnect the DC adapter when the printer is deemed to spare for a long time.
9) Don»t spill water or other electric materials on the printer. In case of this happens, shut down the power imme-
diately.
10) Do not allow the printer to start printing when there is no recording paper installed, otherwise the printhead
and platen roller will be damaged.
11) To ensure quality print and normal lifetime, use recommended paper or paper roll with same quality.
12) Shut down the printer when connecting or disconnecting interfaces connectors 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
printhead durable.
14) Do not disassemble the printer without permission of a technician, even for repairing purpose.
15) Keep this manual carefully at hand for ready reference

1) Please use the recommended paper or its equivalents. Using other types of paper may affect the print quality
and reduce the print head lifetime.
2) Do not paste the paper to the core.
3) If the paper comes in contact with chemical or oil, it may discolor or be less heat sensitive which will greatly
affect the print quality.
4) Do not rub the paper surface with a nail or hard metal, otherwise it may discolor.
5) When the temperature goes up to 70 degrees, paper will discolor. Please don»t use or store paper under such

when a new paper roll with different inner diameter is loaded or when a
new reference point (appropriate amount of remaining paper) for the pa-

the right position along the slide track then tighten the screws.

(3) Semi-automatically loading paper or manually loading paper
A. Semi-automatically loading paper
- Make sure that the power is turned on and the buzzer is warning paper end.
- See figure below. Thread the front end of the paper roll neatly through the
paper feed pass and loose hands when platen roller starts running and
holds the paper.
- The printer will finish the left loading action automatically and In default,
the printer will not print a self-test page subsequently. But user may set the
printer to do so by changing its configuration. To change the configuration,
please consult ≈command set∆for assistance.
- The presenter will feed out the printout.

When one or more of the following phenomena occur, the sensors should be cleaned.
! During printing, the printer sometimes stops printing and alarms paper end when there is paper in fact.
! Doesn»t alarm paper end when paper is end.
! Paper auto-loading action cannot be completed successfully.
! PRESENTER cannot correctly detect whether printout has been taken away.
To clean sensors, following steps given below,
1) Turn off the power
