bizhub 750 with d203 error code

[RayC3]

Anyone come across a D203 error code on a biz 750? It will throw the code at boot up sometimes. And other times it will boot just fine, then throw the code when someone makes a copy after it's been idling for a bit.

I've upgraded firmware to current levels, even tried the anti lockup firmware. Replaced the PRCB as well.
Nothing has helped.

Any suggestions?

What FW level did you upgrade too?

level 31 for the Image, 22 for the controller. I have NVRAM on order for it. I'm suspecting it's corrupt.
