I have run into all types of issues with the mimaki jv3...but this one is odd. I was changing a printhead and dampers...all was going well. When I powered the machine on...everything started off normally, then the panel went blank. The power is still on...but nothing is happening. I am able to move the carriage but that is it. Is it somehow in some maintanence mode. How did I get there...and how do I get back?? I hope someone can help me out!!!
