Why is there a deep and shallow path in the printing of digital printing machine

digital printing machine has become one of the indispensable tools for printing enterprises in recent years. However, as we all know, the equipment and machines will inevitably have problems after being used for a long time. For example, the digital printing machine will have the problem of depth and depth of printing after being used for a long time. Is the nozzle broken? Why does it happen that the weight is accurately weighed? How should users prevent and solve it

1. The nozzle needs debugging. Users need to re adjust the nozzle level and calibration, change the curve, change the software, and properly enhance the print feathering effect

2. There is resistance in the paper receiving and placing system. If the resistance of the paper receiving and releasing system is too large, it will affect the paper feeding speed. If the paper feeding speed is inconsistent with the printing speed, it will cause the generation of deep and shallow channels. Therefore, it is necessary to ensure that the paper receiving and releasing system is normal

3. The trolley frame is not fixed tightly (the trolley shakes when running). The trolley carries the printing machine nozzle. If there is a problem with the trolley frame, it will inevitably lead to abnormal ink jet trajectory of the nozzle

4. Check whether the ink path is blocked or the ink flow is not smooth. If the nozzle is blocked, the printed color will be uneven, which will also cause deep and shallow channels. Therefore, it is necessary to ensure that the nozzle is in a good printing state, and the ink supply system will not be blocked

5. The stepping motor is not installed in place. The stepper motor controls the paper feeding speed by frequent software crashes or other faults. If the stepper motor is not installed in place, it will also cause abnormal paper feeding speed. The paper belt driven by the stepper motor cannot be too loose or too tight

6. Servo motor is not installed in place. The servo motor controls the trolley operation. If it is not installed in place, it will inevitably cause abnormal trolley operation and printing problems

7. Consumables, including printing materials and ink. Some media have uneven texture and unbalanced ink absorption, which will lead to deep and shallow channels; Poor ink is likely to cause blockage of the ink supply system and nozzle, and printing will cause deep and shallow channels. At this time, you can check whether it is a material problem by replacing consumables

why are there deep and shallow channels in the printing of digital printing machine? 4. Parts and components are damaged? It is believed that after reading the above seven points, you have already understood the hole research and repair. If your digital printing machine will show depth and depth, then you can find out the reasons from the above aspects
