Same problem happened with me:
1- New purchased printer (WorkCentre 3025)
2- upgraded to Firmware v3.50.01.10
3- same problem: stuck at "system initialize" after restart or long sleep period.
What i found that when i removed the power cord from the printer (not from wall plug...from the printer !!!) for 5-10min it pass "system initialize" and becaome working again!!
I think it is a firmware problem.
Also i do not like when paper empty and you must open the door and close it again after filling papers...pressing a button can do this...also it is a firmware.
Same happend to me. Bought new device and upgraded it with a new firmware on the first day, so I don't really know if the same problem existed prior upgrading.
I found a solution:
1) unplug the power cord
2) wait for 1 minute
3) plug the cord back in
4) press power and hold it for 15-20 seconds untill some LEDs start blinking again
It is extreamly irritating and I'm positive it is not intentional to be like this. So I'm asking Xerox support, should I change the device or will there soon be a FW upgrade? And yes, opening and closing the door should be fixed with a simple click on the button when paper is out.
This is a general solution for the problems after upgraded a new firmware: just downgrading to the V3.50.01.08 SMP1 Firmware
and you will resolve your problem.
Again this is a great disgrace for Xerox Corporation to released problematic firmwares for WorkCentre 3025.
Generally, it is a problematic situation with all upgrading for Xerox machines as you can see on this site.

Yes, shame on Xerox. Old FW has issues with standby, it takes a while when device is in standby mode to wake up. That's why I upgraded in the first place.
People at Xerox, please fix this ASAP. It's clearly a software glitch.
