850 duplex jam

[Shean]

I have an tek 850 that jams everytime a duplex print is performed. It will print one side then when it partially ejects the paper then refeeds it to print the other side it jams.

!Need a little more info! Open top and lift the blue guide.
check the wiper blade and look for a bit of paper in the
re-feed rollers. Ensure the wiper is snapped into place correctly. Carefully!
{Do this when there is paper stuck}
