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 USB connection to work, should not unplug the
USB cable, or else some printing data may be lost. When printer is
using USB connection to work, the distance of communication
should be within 10 meters, otherwise the printer doesn’t print or
prints rubbish codes.
Too high （above 50℃ ） or too low （under 0.℃ ） environment
temperature and too high (above 85 ％) or too low (under 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

2
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
