This machine throws the code first thing every morning. I changed the Lamp and Inverter PCB, put on a line filter, and updated Firmware. I'm about to try an Engine Board but was looking to see if anyone has had this problem and has any idea's? Thanks.

Is it on a dedicated outlet? Are there things being used on the circuit in the morning that aren't really used the rest of the day? If the machine does it everyday, you might have to go to the customer's office first thing with a line tester so the line can be tested when the machine is turned on. Good luck.
