seen that before, i am not sure , but i think its a firmware problem...
What firmware is currently loaded on your machine?
When coming out of sleep mode or low power mode, everything looks fine but when I hit copy it freezes at "scanning your job". The touchpad is still responsive in that you can go to the different menus, etc. but it can't process any jobs at this point. I can't delete the job either.
Sometimes it'll freeze if I try to do a quick restart via the power button. Only option at that point is to pull the plug from the wall.
Not sure if it's related but this error code is listed throughout the fault history:
05-330
