6700 - Engine Sensor Failure - 391.302.02



I have a Xerox 6700 which will not print. The display shows:


Error 391.302.02 


System error. User intervention is required to Power Off/On the machine; service is required if the problem persists. Print service is not available.



I have restarted several time, left the machine off overnight, and replaced the maintenance kit.


None of these steps have helped. Is there somethign else I can try?

You will need a Service manual for this to make sense (look online) but:


First check Imaging unit link drive P.L. 9.2 Item # 98 if okay then Replace the
Feed Drive. Parts List 9.1 item 4.

Re: 6700 - Engine Sensor Failure - 391.302.02

For clarification:

I just replaced both of these parts on my 6700DN.  Not sure which of the two made the difference but I can confirm, at least in my case, that replacing one or both of the above parts clears this error (391.302.02). 


Thanks Joe!
