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.
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 cleaning the printer with a vacuum cleaner, avoid the printer’s paper outlet from locating
cleaner’s air inlet.
11. The printer’s main structure parts use plated steel. However, rust may be caused to the cut
section.
12. 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.
13. This printer does not support any operations caused by the commands or control commands not
specified in this manual.
