Hello, my Guider IIs (2 years old) stopped during printing, apprx. 5 min. after start. I found the system dead when checking the progress. The power switch doesn't do anything. I checked mains and cable, looked for a fuse, but couldn't find anything. Does someone has an idea how to make it work again or how could I help myself to find the cause of failure. Thanks in advance and best regards, Klaus
