NOTICE
Please read this manual carefully before using the printer!
Notice of Safety
Be sure to use the specified battery and power supply provided by our company. Otherwise it may cause fire,
explosion or damage printer, meanwhile, the battery also may be damaged.
If the printer would not be used for a long time, be sure to take off the battery, otherwise the battery may leak liquid
which is corrosive liquid, if improper operation causes battery leak liquid, and it paste in the skin or clothes, please
rinse it by clean water, if paste in the eyes, please rinse them thoroughly by clean water and see a doctor. Please
do not open the paper case cover when it is printing or just when printing is finished, do not touch the printer head
with hand or body, overheat may cause scald.
Notice of Using
Don’t make the printer print receipt longer than 1m. Otherwise, it might damage the printer.
Water or other liquid should not be spilled into the printer, also the printer should not be appeared in the rain, or else
may cause printer damage.
Please do not open the paper case cover when it is printing, otherwise the printer may work improperly.
If printer is using serial port connection to work, should not unplug the serial line, otherwise the data will be
incomplete. When printer is using Bluetooth connection to work, the distance of communication should be within 10
meters, otherwise the printer doesn’t print or prints rubbish codes.
Though printer can work properly in the 0℃~50℃environment, too high（45℃）or too low（5℃）environment
temperature and too high (85％) or too low (20％) environment humidity both effect the printing quality.
The printer paper roll with poor quality or stored for too long time also may reduce the printing quality even damage
the printer.
Under the black mark detecting mode, the printer requires that the pre-printed black mark is accordant with the
printing rule of black mark (please refer to details in Chapter 4.2), otherwise the black mark can not be detected
correctly.
Be sure to use up the power of the battery before charge up it, as it can ensure the using life of the battery. The
common working life of printer is:the times of charge/discharge≥300, battery performance will decrease with the
charge/discharge times developed.
Notice of Storing
The printer should be placed in such an environment that the temperature is between-20℃and 60℃, and the
relative humidity is between 5% and 95%.
If the printer will be stored for a long time, please be sure to take out the battery, otherwise may damage the battery
and printer.
If the printer will be stored for more than three months, battery should be installed and charged on the printer, which
in avoid of battery damage of self discharge.
Normal thermal paper receipt can’t be kept too long, if you need to keep the receipt for a long period, please choose
long-term effective thermal paper.
The thermal paper should be keep away from high temperature environment and point-blank sunshine, please store
it where is away from light if it have been open.
