If used well, it can barely be used for one year.

The reason is that Epson is a commercial printhead, and the price of Epson is between ¥5,500 and ¥8,000. What is pursued is precision and sacrifice is speed, which is suitable for small-batch customization. Many users report that machines using Epson printheads often have problems. This is indeed true, but it is unfair to blame the problems on Epson printheads. They are used in Japan and have a good reputation. Why are they so acclimated to China? The reason is that Epson has high requirements for ink accuracy. To save costs, some users and even manufacturers use alternative inks. The alternative inks are cheap and greatly reduce the performance in all aspects, which ultimately leads to constant problems during the printing process.
