If the curing system of the UV inkjet printer fails, it will generally cause the picture to become sticky, ink to fall off, and the picture to break upon contact, destroying the picture, and causing the painting work to fail. The curing system of the UV inkjet printer is responsible for hardening the ink, so that the ink dries quickly and adheres tightly to the printing material and is not easily peeled off. So, when the curing system of the UV inkjet printer fails, how should we troubleshoot it?
Fault situation 1. The picture drawn by the UV inkjet printer is not easy to solidify, sticky and unclear. how to respond:
First, check whether the ultraviolet light intensity of the UV glass inkjet printer curing system is working normally. You can increase the ultraviolet intensity appropriately, depending on the situation. If the UV lamp is used for too long, the wick may be worn out, which will weaken the UV light intensity and prevent it from working properly. Please replace the UV lamp.
Secondly, check whether the quality of the remaining UV varnish of the UIV inkjet printer has deteriorated, clotted or precipitated, and replace or add it in time.
If the viscosity of the remaining ink increases, an appropriate amount of adjusting reagent can be added to improve the ink condition.
In addition, control the production efficiency of the UV inkjet printer and do not go too fast, otherwise it will affect the picture accuracy.
UV inkjet printer operators should note that when the curing time is controlled within 0.5 seconds, the power of the corresponding high-pressure mercury lamp must be above 120w/cm. In addition, the UV lamp needs to be checked and replaced regularly, otherwise the UV If the lamp is damaged while the inkjet printer is working, serious malfunctions may occur.
Fault situation 2: The ink of the UV inkjet printer does not dry and ink falls out.
how to respond:
First of all, rely on the UV inkjet printer operator to determine whether the UV inkjet printer printing material needs to be coated, and make a detailed list of the thickness of the coating and other requirements. According to the printing material and coating conditions, analyze the required curing effect and adjust the light power.
Secondly, make sure the ink is qualified. Nowadays, there are many ink manufacturers, and the quality varies greatly. There are many fake products. Inks with substandard quality will cause malfunctions of various UIV inkjet printers and are difficult to clean, causing great damage to UV inkjet printers. Generally speaking, when buying ink, do not change it frequently. Otherwise, when different inks meet, they will produce certain chemical effects and destroy the original quality and color of the ink.
Finally, check whether the UV curing system is functioning properly.
1. Regularly check the UV lamp to prevent aging and damage, resulting in substandard output power and weakening of the curing power.
2. Clean the UV device regularly to ensure it is dust-free, moisture-free and static-free.
