1. Start production and printing without first inking and maintaining the nozzle. When the machine is in standby for more than half an hour, the surface of the nozzle will be slightly dry, so it is necessary to press ink first and then print, so as to ensure that the nozzle can reach the timely printing state and reduce problems such as printing wire drawing and color difference. At the same time, it is recommended to press ink once every 2-3 hours in the printing production process to maintain the nozzle and reduce loss.

2. Printing problems: in the printing process, if the materials are placed at an incorrect height, it is easy to cause quality problems such as printing picture offset and ink floating.

3. The distance between the nozzle and the product surface is too close, which is easy to cause the nozzle to rub against the product surface and damage the nozzle while damaging the product.

4. During printing, the film is damaged due to air leakage.

Therefore, when a novice operates the UV printer, he must place the items flatly, and keep a distance of 2-3mm between the product and the nozzle to avoid collision with the nozzle. The UV printer is equipped with a nozzle anti-collision system, which will automatically stop printing in case of collision. At the same time, it is also equipped with an automatic height measurement system, which can automatically detect the printing height, which greatly ensures the normal operation of the machine and reduces loss.
