It will print either a half test print or a full test print but printer wont acknowledge it complete or not. It will Freeze during the test print either with the UV lamp on or off. Only way to move forward is to restart the machine. I also cannot print a job from Versaworks. It will make a few head passes and then freeze. Not sure what to try an do. It has most recent firmware 3.0. From the test prints, all looks good. I'm starting to wonder if the main board needs replaced. Thank you
