HP Recommended
Product: Designjet 4000

Getting  System Error Code 05.1:10 after 20 minutes of idle time and have to restart. Service manual indicates that the problem is with the cpu fan. I replaced the fan with a new one, same issue. The fan is running fine. I can't figure out how to get into the electronics service menu to check the fan speed? The printer works well otherwise. It does not throw the error while printing, only when idle. Also reinstalled the cpu heat sink with new thermal paste. Any thoughts appreciated.
