Thank you for using the Support Forum. Please take a look at the solution for setting up the power save modes and extend the setting to the maximum time. I do not have the steps for disabling it because as you have been told that is a technician process. Please consider contacting your support centre for further assistance.
Thanks, CherylO-Xerox Community Manager
