MX-3100 weird issue

[dacjkhadley]

I have a MX-3100 that will jam with no paper found at the indicated sensor (FPPD1_S) which is the FED sensor on the FNX9. The client will remove the paper that has made it as far a PPD2, then upon restart, will jam with PPD2_PRI. The client says that it is a copy job, not a print job, but looking at the Job Log, I am not so sure. Possible they are setting a copy job as a print job is being sent?
Anyway, first thing was firmware. Which I freshly downloaded and installed. Then came cleaning and reseating all memory on the MFP. Today I have replaced both the 1gig and 512 MB chips and removed and reseated the EEPROM. I am waiting to see if anything I did today cleared the problem. I know I should do one step at a time but the client is frustrated and just wants it fixed.
Has anyone seen this before? And does anyone have any suggestions?

Re: MX-3100 weird issue

run the copier with finisher disconnected(don't forget to remove dummy punch and mounting bracket to free up shifter) to determine if finisher is problem . when the jam happens there is no paper in finisher entrance? , is it first page or pages after. have had a rash of fnx9 with fed sensor failure and or sensor flag hanging up. does ppd2-pri come up after paper is removed from ps unit or does copier go to ready first. ppd2-pri is paper is in paper stop but the start signal or data hasn't reached laser.
