xerox 7400DN error

Oct 20, 2014
Help! I have a 7400DN printer that was periodically rebooting. The error log showed an error U5. Armed with that information I replaced the Engine Controller board with a new one. The error no longer shows but the printer is continuing to reboot itself every 5 to 10 minutes. Does any one have any ideas to try next or can point me in a direction to go?

Thanks in advance
