Abnormal wire properties of auxiliary equipmentThis refers to insufficient ink lines between the entire nozzle or multiple consecutive spray points. The reason for this type of line pulling is that the nozzle does not spray ink and the UV flatbed printing ink supply is insufficient, or the negative pressure of the UV flatbed printing is unstable due to ink sticking above the nozzle. The solution is to replace the corresponding circuit board and negative pressure pump or eliminate the defoaming fault, and increase the frequency of the defoaming pump. Of course, another option is to increase the frequency of ink supply pumps, regularly replace filters, and eliminate abnormal properties of auxiliary equipment cables.So when using a UV printer, there are some minor issues that do not need to be adjusted by professional information personnel. You just need to see the problem and replace and clean it yourself. And it generally does not cause major problems to the machine, unless it is caused by improper use by the user. As long as users pay more attention to observation and daily cleaning during the use of UV printers, the occurrence of such problems can be reduced. We are a supplier of UV printers. Please feel free to contact us if you have any needs!

All lasers are considered Class IV and are recommended for operation as Class I systems to ensure operator safety. This can be achieved by installing beam shields around the laser marking points on the material. The design, size, and material used to manufacture beam shielding depend on the type of laser used. If all components of the beam shielding are not in the correct position, interlocking devices are usually included to stop operation. Protection is the responsibility of the buyer, but Weidijie laser experts are happy to provide guidance on beam shielding and, if necessary, offer complete solutions as well as Class I certification from third-party suppliers.In addition to beam shielding, Videojet also recommends using smoke exhaust to ensure the safety of operators. The smoke exhaust not only prevents operators from inhaling smoke due to laser marking, but also helps to keep the laser optical components clean and ensure the quality of coding.

software systemThe software system is the command brain of the UV inkjet printer. It can be imagined that there is a problem with the brain. Can it work normally! If there is a software problem with the patch machine, it is necessary to familiarize oneself with the software system of the machine and perform the correct operation before operation.mechanical failure1. The movement trajectory of the UV inkjet printer nozzle car is obstructed or the power is insufficient; This situation rarely occurs on new devices, and may occur on devices that have been in use for a longer period of time. The inspection method is to remove the motor belt, separate the suction nozzle trolley from the motor, and then push the trolley downwards by hand. If the movement is not smooth, replace the track or slider, because the resistance of the car is high at this time, which will cause mechanical and electrical failure and crash.2. Faulty nozzle motor; There are many crashes caused by such malfunctions. The nozzle motor of UV coding machine is mainly divided into two types: AC and DC. Among them, AC type faults are relatively rare and are more common in crashes caused by wear and tear after long-term use. The DC type has many faults. Not only will it crash due to wear and tear, but unexpected malfunctions will also occur, causing headaches.Internal interferenceThe interference sources of UV inkjet printers include external interference and internal interference. Here we mainly analyze internal interference:1. Data transmission interference: Data cables that are not shielded or have poor shielding functions are prone to interference, leading to unstable operation. Therefore, high-performance data cables should be selected. It is particularly pointed out that although the fiber has excellent resistance to dry winding, it is not suitable for mobile environments with frequent bending.2. Spark interference: If UV coding machines use components that are prone to spark, it can cause many unexpected malfunctions.
