yes you are right i confused sorry
I hate to sound like tech support, but, is it running the latest firmware? These things were riddled with bugs from production.

Went back today and tried swapping feed units, no help. Did not try updating firmware but probably will try as I have nothing to lose. Thanks for all the input. If I figure it out I will let you know what it was.

I'm willing to bet that it's paper dust on the registration sensor. Take the dev unit out, remove the 2 screws on the plate underneath it (the top of the registration) and there's a sensor there which is prone to being covered in paper dust.
Also check the black mylar guides in the registration as these get marked with a white line and eventually tear over time.
I see that Vargue is being as objectionable and wrong as ever!
Just to check, the machine does not jam on single sided from the ADF, so invertion is ok?
Have you inspected the duplex unit plugs / sockets VERY carefully? I have had VERY small bits of paper in the sockets cause strange problems, if there is toner on the paper it's very difficult to see. You need to get a "pointy thing" and scrape the inside of the socket.
The older versions with 2 duplex transport clutches used to have similar problems when the clutches slipped, may be worth swapping the duplex unit for test if possible.
I agree that the reg sensor could case the issue, also the relay sensor (the one before registration).
The vertical transport relay drive can cause odd faults. check the motor and one way bearing. Is there any noise as the fault occurs (Stepper motor?)
Does the fault happen feeding from all trays?
Good luck!
Thanks for responding. I did try a whole different duplex unit, inversion unit and registration section unit. On each i cleaned all the sensors and guiide plates. Single sided copying has no problem at all. Also, you can run one or two duplex copies no problem but when you try multiple , 3-5 plus , is when it jams. Always at reg rollers. It seems that reg rollers dont turn on quick enough and then paper bacs up and gate b2 pops open.
I did look behind duplex unit with a flashlighta at the plug but did not see any paper stucK. All drawers jam on duplex, simplex runs good.
format the hdd......if it runs well , then change hdd.....
