Wrong handling of the printer may cause its performance declined and the product damaged. Please
read the notes below before handling.
1.
Static discharge prevention must be made for installation and removal of the printer to protect IC
and other electrical parts. Connect it to the earth ground. It is also requested to remove the static
from body of the person before handling, especially, the input terminal.
2.
Avoid excessive force to the input terminal for handling.
3.
When any type of paper, other than specified in this manual, is used, it may cause deterioration
of the print quality and thermal head reliability.
Examples of troubles
1) Print quality deterioration by using low sensitivity paper.
2) Thermal head wears due to roughness of paper surface.
3) Sticking between heat receipt layer and thermal head, and vibration noise during printing.
4) Print ink disappears on low print durability paper.
5) Electrolyte corrosion on thermal head due to low quality of heat receipt layer.
4.
Avoid printing with no paper loaded. It damages platen and thermal head, printer life will be
shorten.
5.
Do not scrabble thermal head with sharp edge or something hard, or give impact. The heat
element may be damaged.
6.
Set the power of printer off before connecting or removing connecters.
7.
When printing in high speed under low temperature of high humidity environment, the paper may
be stained by moisture that appears from paper, or the printer may have condensation. Avoid
dew from dropping down to the thermal head that may cause electrolyte corrosion. Turn the
power off until any dew is removed.
8.
The printer is not protected from water or dew formed. Do not water the printer or handle it with a
wet hand, which may cause damage to the printer due to short circuit, or heat or fire.
9.
The printer is not protected from dust or dirt. If it is used at dusty place, the thermal head may be
damaged or paper feed is not operated properly.
10. When cooling the printer with a fan, avoid the printer's paper outlet from locating fan's air inlet. It
may cause mal-function of printer.
11. Reflection type of infrared ray sensors are used at some locations in the printer. Direct sun light
may cause mal-function of printer. Avoid from such a location for installation.
12. This printer does not support any operations caused by the commands or control commands not
specified in this manual.
13. The printer's main structure parts use plated steel. However, rust may be caused to the cut section.
14. In order to prevent excess current, please put elemental device to external 24V power line
(Please refer to the power supply specification for the details), and also put fuse.
15. Please plug off the printer when you do not use the product for a long time. Please also insert
paper between the platen.
16. When paper jam occurred, please make sure to slowly remove the paper to paper exit direction
after head up status.
17. The product is designed to use with general electronic devices (Computer, PC, OA, others). This
is not designed and not guaranteed to use with extremely high quality, high reliability product or
product whose failure may danger human life (Atomic power control device, aerospace aircraft
devices, Transportation devices, Traffic signal devices, Ignition control devices, Medical devices,
other safety equipments: we call "Specific application" thereafter). Users take full responsibility
for using with such specific application.
18. The product uses part that includes GaAS (Gallium arsenide). Please do not break the product,
no chemical splitting ,otherwise it may harm human with such part broken pieces.
