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. Confirm whether the purchased carbon belt specifications are inconsistent with the previous, such as the number of meters is too large;
2. The carbon tape slitting is bad, resulting in the dislocation of the paper axis core inside the carbon tape, which can not be normally installed to the printer;
3. When the tape is processed, the winding is too tight or too relaxed, resulting in the carbon tape can not be matched with the printer;
4. The tolerance of the inner diameter of the paper core is too large or too small: it can not be loaded into the printer or the shaft can not get up the carbon belt.
1. Observe whether the tension of the last few meters of carbon tape coil is too tight;

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 carbon belt is supplied for a long time with 300 meters, it is now supplied for 450 meters, resulting in tension instability.
6. If the printing head is new, the printing head may not be installed properly. Reinstall the printing head.
7. The carbon strip has wrinkled phenomenon before delivery, which is a product quality problem.
1. Confirm whether the printing head button on the lighter side is pressed tightly, excluding artificial.
2. Clean the light part of the printing head and roller, there may be dust and thick carbon tape accumulation, and the removal is not complete.
3. Whether the film surface of the carbon belt is uniform or not, whether there is bad situation.
4. The printing side is light, and the roller is seriously worn by naked eyes. It is suggested to replace the roller.
5. The printing side is light, and the printing head is seriously worn by naked eye. It is recommended to replace the printing head.
6. The pressure on both sides of the printing head is unbalanced, and the pressure on the lighter side of the bar code printer should be increased.
7. Adjust the front and rear positions of the printing head on the lighter side of the printer to the highest point on the horizontal plane where the printing head and roller are located.
1. Pick up the printed carbon tape and observe with naked eyes whether the coating of the carbon tape (or understood as film surface or surface layer) is uniform.
2. Use industrial alcohol and cotton to clean the print head and roller and wipe off dust.
3. Increase the printing temperature and slow down the printing speed to see if it is ideal.

The printer is loaded with paper and the top cover is covered. When the printer beeps twice and the indicator light turns blue, long press the "paper off" button for about 3 seconds, and release the "paper off" button. Then the printer will automatically move a section of paper for verification and learning.
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.
Cause: the photocoupler can not sense the position of the paper, the paper specification set by the driver does not meet the actual paper.
The solution:
1) Adjustment of optocoupler position:
Black label paper
1. Adjust the optocoupler at the bottom of the paper to minimize interference.
2. Set the actual paper specifications for the driver, and the sensor type is black mark.
The label paper
1. Adjust the optocoupler at the bottom of the paper to minimize interference.
2. Actuation set actual paper specifications, sensor type is clearance.
Continuous feed
1. Adjust the optocoupler at the bottom of the paper to minimize interference.
2. The actual paper specification is set for the driver, and the sensor type is continuous.
2）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.
3. Check whether the port configuration is correct.
4. If the USB port is used:
A. If A computer is connected to multiple USB devices, the ports may contain multiple ports, such as USB001, USB002, USB003, etc. You need to select the correct ports to print properly. (You can also directly select the port RONGTA USB, no matter which USB port is connected to the computer can be used)
B. If all USB ports are not working, you can go to [Device Manager] -- [Universal Serial Bus Controller] to check whether "USB print support" is displayed. If not, the port is not identified.
Solution: Replace the computer USB port, replace the USB data cable.
5. If the serial port is used: The port may be occupied, causing printing failures. Release the occupied serial port before printing.
6. If a network port is used: The printer and router may not be in the same network segment. Ping the printer to check whether the communication is normal.
7. If the use of parallel port: need to select the correct parallel port, in [device manager] - [port] to check the computer parallel port is LTP several.
