If you have a 7845 that keeps rebooting, 1 thing that can help determine why is by using the POST codes. (Power On Self Test) Look for the 7 segment display located near the network plug. Just before the machine reboots, see what is showing in this display. There are more than one reason for constant reboots. You can have corrupt software (would require an altboot or a forced altboot). It can be as simple as a corrupt print job trying to print (booting up with the network cable out lets it boot up ready, plugging the cable back in causes the reboot - fix is the clear the print queue on the computer printing to it), It could be defective SD card or a bad single board controller. Check that the small fan on the SBC is working, if it's not, your SBC might be blown.

Its not dc130, its DC131. 616-014 is if you are getting a message on the screen that the machine is in a "non customer mode". Nothing to do with what you are having. Are you telling me that the machine keeps restarting on it's own or that it comes up to a screen that tells you to reboot the machine? I would suggest that you re-enter diagnostic mode and look to see what fault codes are being recorded. Again, POST codes are helpful. If the machine keeps rebooting on it's own, what is the POST code that is displayed just before the machine shuts off and begins the boot up again? That will tell you at what part of the boot up sequence the machine stops at and what is the likely cause of the failure to complete boot up. I would start with doing a FORCED ALTBOOT to load fresh new software. If the machine does not complete software install you may have a bad HDD, SD card, SBC. Check the SBC cooling fan. It it's ceased up, you probably need a new SBC due to overheating.

Re: xerox 7845 system error

With that POST code, you should do the following in this order:

1. Reload system software. (Altboot or Forced Altoboot)
2. If problem persists, replace Hard Drive and then reload system software.
3. If problem persists, replace the singe board controller.

System error can mean different things on the 78xx series, most of the time its a bad fuser but to be more certain technicians check for faults codes listed in service mode. Im not sure how you got that nvm setting based on so little information but if it worked great. I'm assuming it did not work otherwise you wouldnt have the need to ask for advise lol
