Sometimes I found myself just a genius, because a few days ago our company’s UV printer had some problems, of course, the problem was caused by a misoperation of a colleague of our company. He did not think of the solution for a half day, just when I passed by. I wanted to help him to see what the UV printer was, and there was no way who made me so passionate all the time. I was just trying to see if I could fix it, and I didn’t think I really had the UV printer repaired myself, and my colleague said UV printer now. Use it better than before.
