1、 The placement and environment of the printer

　　The printer needs to be operated on a flat surface, with its front cover closed to prevent dust from entering and accumulating inside the device. When the device is not turned off, the printer cable should not be directly plugged or unplugged, as it can seriously damage the PC motherboard. It is prohibited to place other debris on the body of the tablet printer to avoid adverse effects on the platform, interior, and outer shell of the device.

　　2、 Ink cartridges require frequent calibration

　　When the output pattern of the printer is not clear, if the printing still does not work well after several consecutive cleaning, it may be that the ink has been used up and the ink cartridge needs to be replaced in a timely manner. Calibration is required when reinstalling or replacing ink cartridges, which is beneficial for improving equipment accuracy and quality.

　　3、 Spray nozzle anti drying

　　When the nozzle of a tablet printer dries up, it is easy to cause blockage. It is especially important to pay attention when the weather is dry in winter. It is recommended that you soak a clean cotton cloth (dust-free cloth) first and place it on the head of the device. Due to the natural evaporation of water over time, the humidity of the air increases, which helps to slow down the drying rate of the printer's ink.
