If there are some spots on the label you printed, it is because there is dust in your printer and it needs to be cleaned promptly. It is recommended that you use special cleaning tools when cleaning, so that the printer can be well protected from damage.
1. Use industrial alcohol and cotton to clean the print head and roller and wipe off dust.
2. Check the roller, whether there is any trace of knife scraping, which causes unclear 360 degree fixed position when printing, and replace the roller.
3. Check whether the needle of the print head is broken at the fixed position. Replace the print head with a new one.
1. Check whether the paper passes through the sensor.
2. Observe whether the sensor part of the label is blocked by labels, dust, etc., and clean it with alcohol.
3. Check whether the label sizes of printer drivers and software items on the computer side are consistent with the actual Settings, including the spacing.
4. Measure paper on the printer again. If the printer fails, restore the factory defaults.
5. After a long time of printer, the electrical pressure of label sensor is weak, aging and other phenomena, it is recommended to replace it.
6. If it still doesn't work, find a new firmware version and refresh the printer to see if it works.
7. The transmittance of the bottom paper on the label is abnormal.
1. Use industrial alcohol and cotton to clean the print head and roller and wipe off dust.
2. Observe the corresponding position of the roller, see whether there is a knife scraping, and depression marks, replace the new roller.
1. The printing temperature is too high. Reduce the printing temperature.
2. The left and right pressure of the printer may be too high on one side. It is suggested to adjust it to a proper position.
3. The position of the front baffle of the printing head is loose or the difference between the left and right positions is too large, which leads to this situation.
4. The printing head part of the printer may be too skewed to the front of the roller on the left and backward on the right, resulting in wrinkles.
5. If the printing head is new, the printing head may not be installed properly. Reinstall the printing head.

1. Whether the paper is smooth and the limit plate is adjusted properly.
2. Phenomenon 1:
Single label paper, left and right or up and down deviation, drive adjustment non-printing area, default all 0.
Adjust the value of the non-print area as follows:
Left: input positive value, the overall print area is right-biased according to the input value; Right: input positive value, the overall print area is biased to the left according to the input value.
Up: input positive value, the overall printing area is biased according to the input value; Down: input a positive value, and the overall print area is biased up according to the input value.
3. Phenomenon two: up and down gradually offset, print more, more up or down.
Cause: paper gap identification problem
The solution:
A. Check whether the paper type read by the self-check page/tool is the same as the actual paper type. If not, change the paper type.
B. The driver sets the paper specifications to the actual paper specifications.
The paper specification set by the driver does not conform to the actual paper, set the paper specification:
A. Paper specifications: Right-click printer Driver - Printer Properties - Preferences - Paper specifications.
B. Sensor type: Preferences - Advanced Settings - Sensor type.
1. Check whether the driver is correctly installed and the printer model in use.
2. Check whether the driver is reinstalled and delete redundant drivers.
