Barcode printer users, especially new users, must understand that a very important point is that although the bar code printer has many brands and models, it works the same way. That is to say, bar code printers of different brands and uses may have different operations, but the difference is not large, so the cause of the failure and the solution are also interoperable. Knowing this, we will be more comfortable when faced with different brands and models of barcode machines.
The following 17 points are summarized by Xiaobian based on years of experience, common problems and solutions for barcode printers. Because there are many reasons for a problem under normal circumstances, you need to follow the steps one by one. Just follow the instructions and try to operate it once or twice. If you have problems later, you don't have to worry about it.

1. The label is not printed clearly, the color is white, and the phenomenon is rough.
1 Pick up the ribbon that is currently printed, and visually observe whether the coating of the ribbon (or understanding the film surface and the surface layer) is uniform;
2 Take industrial alcohol and cotton to clean the print head and roller and wipe off the dust;
3 Increase the printing temperature, slow down the printing speed, and see if it is ideal;
4 adjust the overall pressure of the printer to see if it is resolved;
5 Whether the label and the ribbon match, and the printing compatibility is ideal;
6 bar code printer resolution is too low, it is recommended to replace high-definition print head, or bar code printer;
7 The ribbon supply shaft or the reel pull tension is not accurate and needs to be adjusted to the appropriate size;
2. Printed labels are clear on one side and light on the side
1Check if the print head button on the side is tight, and eliminate the artificial (similar to the Beiyang 2200E and other machines)
2 Clean the print head and the roller part on the side of the light side. There may be dust and thick carbon tape accumulation, and the cleaning is not complete;
Whether the film surface of the 3 carbon ribbon is uniform and whether there is a bad condition;
4 printing is too light here, the roller is seriously worn by the naked eye, it is recommended to replace the roller;
5 printing is too light, the naked eye is observing the wear of the print head, it is recommended to replace the print head;
6 The pressure on both sides of the print head is unbalanced, and it is necessary to increase the pressure of the print head on the side of the bar code printer;
7Adjust the front and rear position of the print head on the side of the printer, and adjust the print head and the roller to the highest point on the horizontal plane;
3. Printed labels appear white wrinkles, diagonal strips
1 printing temperature is too high, it is recommended to reduce the printing temperature;
2 The left and right pressure of the printer, maybe one side is too large, it is recommended to adjust to the appropriate position;
3 The front flap of the print head portion has a loose position or a large difference between the left and right positions, which causes this;
4 The print head part of the printer, maybe the left side is too far ahead of the roller, and the right side is behind, causing wrinkles;
5 If the carbon ribbon supplied is 300 meters for a long time, it is now 450 meters, resulting in unstable tension;
6 such as: new print head, maybe the print head is not installed smoothly, re-installation;
7 ribbons have wrinkles at the factory, which is a product quality problem;
4. Print the contents of the label, each part will be missing a part of the corresponding location
1 Use industrial alcohol and cotton to clean the print head and roller and wipe off the dust;
2 Pick up the ribbon that is currently printed, and visually observe whether the coating of the ribbon is uniform;
3 Observe the corresponding position of the roller to see if there is a knife scraping, and the trace of the recess, replace the new roller;
5. The barcode printer makes a squeaky sound, and it feels like the label sticks to the ribbon.
1 printing temperature is too high, it is recommended to reduce the printing temperature to see if it can be solved;
2 Observe that the tension of the ribbon is too tight, which is really the case, which is a product quality problem;
3 face coating and back coating stick together, it is not easy to pull down, it is a product quality problem;
4 carbon with static phenomenon;
6. The ribbon has a severe electrostatic phenomenon when the machine is printing.
1 It is recommended to do static test, wipe the cloth to see if it is still smoking ash;
2 reduce the printing temperature;
3 Place the ribbon in a humid environment to reduce static electricity;
4 If the printer has an electrostatic brush, damaged and unstable, it is recommended to replace it with a new one;
7. When the label is printed, one or two blank sheets of paper appear, and the paper is leaked.
1 Check the man-made, install the problem, whether it is installed under the sensor;
2 Observe whether the label sensor part has a label, dust, etc., and clear and alcohol clean;
3 Check whether the label size setting of the printer driver and software item on the computer side matches the actual, including the spacing;
4Re-measure the paper to the printer, if not, restore the factory value operation;
5 After the printer has been used for a long time, the voltage of the tag sensor is weak, aging, etc., it is recommended to replace it;
6 If it still doesn't work, find a new firmware version to refresh the printer to see if it is resolved.
The transparency of the 7-label bottom paper is not normal;
8. When printing, the ribbon will not turn, and the label paper will turn.
1 Check the pressure of the printer first, if the unilateral is too large, it is recommended to adjust to the appropriate size;
2 Such as: whether the factory is outside the carbon, or the inner and outer carbon belt can be used, this link checks whether the consumables have any errors;
Whether the cutting of the 3 carbon ribbon is bad (including whether the paper shaft core is misaligned left and right);
4 Change to thermal paper without carbon ribbon printing, observe whether the ribbon shaft rotates. If the installation is not in place in the early stage, the machine will be broken if it is not turned (the inner spring of the ribbon shaft and the aging voltage of the ribbon sensor are too small);
The surface coating and back coating of the 5 carbon ribbon are stuck together, which is a product quality problem;
9. The label will not go when printed, the ribbon will go.
1 Check the pressure of the printer first, if the unilateral is too large, it is recommended to adjust to the appropriate size;
2The printer roller is very smooth, there is no strong friction, and it is replaced with new ones;
3 Whether the roller motor drive is damaged or the belt on the motor is worn, it is recommended to replace it with a new one;
4 Check whether the printer printing mode is in the thermal mode, and make corresponding settings or factory values.
10. Each time the ribbon starts to print, the first one will have a black line printed on it.
1 Try to reduce the printing temperature properly;
2 The front flap of the print head part is loose or too up and down. It is recommended to adjust to the proper position;
3 When the printer prints, the reverse position function is turned on, which causes this;
11. Under what circumstances is the print temperature set by the barcode printer is too high?
1 will cause a broken carbon ribbon;
2 The printed label content looks like a watermark, whitening phenomenon;
3 The ribbon and the label will stick together, the label and the ribbon will not be transported, and the printer will report the error;
12. The printed label has white strips
1 Use industrial alcohol and cotton to clean the print head and roller and wipe off the dust;
2 Check the roller, whether there is a knife scraping and other traces, causing the 360 ​​degree fixed position when printing is not clear, replace the roller;
3 Whether the print head is in a fixed position and the needle is replaced, and the new print head is replaced;
4 Whether there is a white line in the fixed position of the ribbon, which is a product quality problem;
13. The barcode printer ribbon has no more left.
1 Observe whether the tension of the last few meters of ribbon roll is too tight;
2 Observe whether the top and back layers of the last few meters of carbon ribbon are stuck together, and it is not easy to pull them down;
3 Confirm whether the purchased ribbon specifications are different from the previous ones, such as the number of meters is too large;
4 carbon belts have a large static electricity;
5 The ribbon tension at the supply end of the printer is too small, and a new spring needs to be replaced.
14. The ribbon will not be installed.
1 Confirm whether the purchased ribbon specifications are different from the previous ones, such as the number of meters is too large;
2 The carbon ribbon is poorly cut, causing the left and right paper cores of the ribbon to be misaligned to the left and right, and cannot be properly installed in the printer;
3 The tape is too tight or too loose when it is processed, which makes it impossible to match the printer when the ribbon is running;
4 The tolerance of the inner diameter of the paper core is too large or too small: it does not fit into the printer or the ribbon does not get up.
15. The paper core of the ribbon is not standard and is a product quality problem.
1 carbon belt inner paper shaft core left and right misalignment;
2 The inner core of the carbon ribbon has signs of flattening;
3 tension is too tight, the ribbon is too tight, resulting in a small paper tube pressure, not up to the standard paper tube diameter;
16. Why is the ribbon broken?
1 Pick up the ribbon that is currently printed, and visually observe whether the coating of the ribbon (or understanding the film surface and the surface layer) is uniform;
2 reduce the printing temperature to see if it is ideal;
3 set up to hit the printer, such as the ribbon supply end of the tension is too tight;
4 carbon ribbon coating is too thin, which is a product quality problem;
5 carbon ribbon back coating is too weak, which is a product quality problem;
17. Ribbon, hand off the powder
1 Pick up the ribbon that is currently printed, and visually observe whether the coating of the ribbon (or understanding the film surface and the surface layer) is uniform;
2 The carbon ribbon used, the ambient temperature is too low and the time is too long, causing this phenomenon;
3 The coating of the carbon ribbon is too thick, resulting in powder drop, which is a product quality problem;
