Power supply: 2000mAh rechargeable lithium battery

8. Battery warning: When the rechargeable battery is about to run out of power, the printer's battery indicator lights will all turn off, and the printer's error indicator light (red) will remain on.

Adapter charging: Fully charged in 5 hours;

Usable time on a single charge: Under normal circumstances, it can print 200 meters or 6 hours continuously. This parameter is for reference only. After prolonged use, the battery capacity may decrease, and the printing time cannot be guaranteed.

1) Do not immerse the printer in water or expose it to rain for extended periods, as this may damage the printer.

2) Do not open the paper tray cover during printing, otherwise the printer may malfunction.

3) When using serial port printing, the serial cable must not be unplugged during the printing process, otherwise the printed data may be incomplete.

4) When using infrared printing, the infrared window of the main device must be aligned with the infrared window of the printer during the printing process. The distance should not exceed 50 cm and the angle should not exceed 30 degrees. Otherwise, it may cause garbled characters or failure to print.

5) Although the printer can operate stably from -10℃ to 50℃, excessively high ambient temperatures (45℃) or excessively low ambient temperatures (5℃) will reduce print quality. Excessively high ambient humidity (above 85% relative humidity) or excessively low ambient humidity (below 20% relative humidity) will also reduce print quality.

6) Using inferior printing paper or printing paper that has been stored for too long may reduce print quality or even damage the printer.

7) When the printer is working in black mark detection mode (when printing pre-printed tickets with black marks), the black marks pre-printed on the printing paper must conform to the black mark printing specifications (see 4.2 Black Mark Detection Instructions). Otherwise, the printer may not be able to accurately detect the black marks.

8) Before charging the printer, try to use up all the battery power before charging. This can effectively ensure the battery's lifespan.
