This morning at work I went to turn on our Barudan single head, and as usual the origin thing prompts on the screen. I hit the button, and the pantograph slides all the way to the back and gets stuck and won’t move forward on it’s own. No settings were changed last time it was on. Tried restarting and unplugging it, keeps doing the same thing. Google is useless for troubleshooting this. Do you have any suggestions???? Thank you in advance!
