Disable Sleep Mode WorkCentre 5945 v1

[Radium]

We have a number of brand new Xerox printers here, but the main one this post concerns is the Xerox WorkCentre 5945 v1
The device goes into sleep mode and has trouble waking up from said mode.
I want to turn off sleep mode *permanently*
On our 5875s it's in the technician's diagnostic mode (star pound stop key combo) and it's an NVM code. Apparently the same NVM code doesn't seem to work for the 5945 and Xerox is giving us the runaround on how to disable this.

So, turning to the community for help.
