Read carefully Before Using the Printer

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.

*2: A sufficient volume of power supply is required to maintain print quality due to high peak current
that may run according to printing.
*3: If power supply cable is excessively long, the operation may become unstable. Cable should be
made as short as possible. If not available, connect cables near the printer and place an electrolysis

condenser of 2200μ between power supply and ground. Voltage resistance should be higher than

35V.
* For preventing from static electric discharge, make sure to connect FG wire.

2.4 Reliability

1) Head life : Average resistance change rate to head less than 15%, except

Pulse : More than 100 million pulses (with recommended paper)
Wear distance : More than 50 km (with recommended paper)

2) Operation environment : Temperature 0 – 45℃

3) Storage environment : Temperature -20 - 60℃

* When storing for a long time, paper must be kept loaded between head and platen.

4) Frame Ground (FG) wire

The FG wire (Green and Yellow) is coming from the printer body. Make sure to ground the wire
near the body frame when installing the printer. FG grounding is effective for minimizing the noise
level, preventing from SED and maintaining the FG safety for head, cutter, body frame, power
supply and Data connectors.
