Every morning the machine will not wake up from sleep mode, has the SC672-11 error, and the customer has to unplug / plug it in and then it is fine the entire day. Next morning same thing.
I am the Account Manager in this particular account and I have the Service Department saying the voltage to the machine is the cause. We have ESP Surgex on it where we can log in and see that indeed it does have quite a variation.
However, during the day we have NOT seen any surges or under-voltages while we watch the gauge, it holds steady at about 120 volts.
My contention is that it is not the voltage variation, but possibly the USB cable connection that runs from the op panel to the controller board. It is either not well connected or failing entirely due to the cable-tie crimping the USB cable, as mentioned in other posts. It is not allowing the machine to wake up. Or maybe even the hard drive not working as a second alternative. Maybe the voltage surges caused this in the first place, I am not disputing that. but I don't think it is the reason going forward. Hope I am making sense!
Thank you for any guidance.
