Single side printing is working fine. Duplex printing paper jams at reversal section. It goes to the duplex exit and then solenoid pulls the gate when it's reversing it jams there entering the duplex Gray rollers. Machine is indicating jam at 14 number but paper is not activating that sensor. EXIT SECTION replaced. Reversal section replaced but still paper is jamming at the same location.
On similar Minolta style engines I've seen:
*rusting or damaged duplex clutch
*worn LCF rollers
*dirty ADU rollers
*duplex flag is worn down
*wire harness to the lower duplex sensor is mis-routed over the flag, preventing the flag from moving smoothly.

If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.
