In the event of a crash in the digital uv printer, the consequences are more serious, and generally a large number of pictures are invalidated, resulting in no small loss. The crash occurs when the printing is suddenly stopped automatically during the printing process. The cause of this phenomenon is more complicated. The following is a detailed analysis of the causes and countermeasures of the crash. One type is completely dead, that is, the motion system is completely stopped. The other type is a non-complete crash, which is characterized by a break in print data, but the motion system is still working. The latter brings greater harm and loss than the former.
1. Mechanical failure
Case 1: The motion track of the printhead car is blocked or underpowered. This situation hardly appears on new devices, and devices that take longer to use may appear. The method of inspection is to remove the motor belt, separate the printhead trolley from the motor, and then push the trolley down by hand. If the movement is not smooth, the track or slider should be replaced, because the resistance to the car is large at this time, which will cause the electromechanical malfunction and crash.
Case 2: The print head motor is faulty. Such faults lead to more crashes, and the printhead motors of UV printers are mainly divided into two types, AC and DC. Among them, the AC type has relatively few failures, which is often caused by a long time of use due to wear and tear. The DC type has many failures, and it not only causes a crash due to wear and tear, but also causes unexpected failures, which is a headache.
a. Data transmission interference: Data cables that do not have shielding or poor shielding function are susceptible to interference and cause unstable operation. Therefore, it is necessary to use a data cable with excellent performance and high quality. In particular, it is proposed that the optical fiber has excellent anti-drying properties, but it is not suitable for a frequently bent sports environment.
b. Spark interference: If a component that is prone to sparking is used in a UV printer, it will cause many unpredictable faults.
3. Software system
The software system is the commanding brain of the inkjet UV printer. It is conceivable that the brain has a problem and can it work normally? Software problems occur on the inkjet printer.
In the event of a crash, the entire system is in a state of confusion and the digital UV printer device and software must be restarted. If this kind of fault is rare, it is normal (people will make mistakes, let alone the machine?), but there are always problems.
