Xerox wc 5655 duplex problem

[awad]

Hi Dears

I have xerox WC5655 copying very good in single copies with duplex function.

But when making duplex group " group of 2 side copies" giving jam after 7 to 10 groups.

I Upgrade firmware but same problem again.

I changed all feed rollers and duplex clutch.

Any advice.

Thanks in advance
