This is the printer we bought from We Print Solutions, Germany in Feb 2022 It has 2 heads Epson dx5, UV DX5 Software it uses is MAINTOP We cannot regulate red and yellow in printing. It does not come out and failure happened during printing. ANYONE CAN HELP? ANYONE WITH GOOD INSTRUCTIONS IN ENGLISH FOR THIS SOFTWARE? Our seller is probably a one man band company and we are completely cheated as we have no technical support, not even a manual. It was promised but nothing...
