UV printer factory tutor teaches you how to distinguish second-hand UV printers
The UV printer industry has developed for several years and has gained recognition from many users. There are also some second-hand refurbished machines on the market, which are difficult to prevent.
Let me share some identification methods with you.
1. Observe whether the machine’s nozzle has been used, and the difference between used and unused nozzles is visible to the naked eye.
2. Secondly, check if there is ink in the ink tube, ink path, and nozzle, and if so, it indicates that the machine has been used;
3. Open the base of the nozzle and observe the internal components. Generally, there are date codes on the components. If the dates of each component differ too much, it indicates that the machine has been used for a period of time and the components inside have also been replaced.
4. The printing effect of the new nozzle is slightly worse when it is first used than when it has been used for a period of time. Moreover, for old nozzles, especially those specifically designed for white ink, it is important to pay attention to whether the channels of the nozzles are burnt out and whether the spray holes are blocked.
5. When we look at the machine, we can directly check the condition of the UV printer head parts. 6. Check if the coding on the UV printer motherboard is consistent with the coding on the nozzle. The coding on the new machine is consistent.
By combining several methods of appeal, we can better distinguish between second-hand and brand new UV printers, and remind users that it is best to purchase UV printers from reputable manufacturers.
