Hello, i have a Mimaki UCJV300-160 and the lamp 1 started giving me temp high error, if I continue printing then the machine gives UV UNIT OVER HEAT error 706 and turns off, I think the blower fan is really dusty and almost no air comes out, but I don’t know how to open it to clean it and can’t find anything on the manual on this topic, do you guys know how to open it and clean it? Any help or tip is appreciated
