Image distorted in the second side in iRADVC 7055.

[Ingranaggio_rotto]

Yes, I'm still me!
With another problem!

I have a 7055 iRADVC that when printing or copying two-sided,
the image of the back is printed always crooked ....!
I have verified the entrance of the sheet from the group ADU in xerographic unit and in fact
enters a bit misaligned.
How can I correct this malfunction?

Thank You!
