    Ricoh 161 Duplex jams

    I have a 161 that jams when duplexing I have cleaned the one way bearing and that seems to take care of it for 3-4 weeks then they call back about duplex jamming. They havent complained about single sided jams. I get mainly Jam code 60, 210,211. of course it doesnt jam while Im there, any thoughts would be greatly apreciated.

    I think you pretty much hit the nail on the head. I tend to replace the one way and shaft as a pair.
    It's 106 miles to Chicago. We've got a full tank of gas, half a pack of cigarettes, it's dark and we're wearing sunglasses.

    Hit it.

      Rough up the shaft where the bearing rides.
      The bearing tends to polish the shaft to the point that it slips.
      I use a scotch pad back and forth, so it looks dull.
      Why do they call it common sense?

      If it were common, wouldn't everyone have it?

        Agree a hundred percent with nmfaxman. It does NO GOOD to clean the one way and NOT rough up the shaft it rides on.

          I only clean the one way if I don't have a replacement on me. They are real cheap to replace and will usually prevent a recall. Like the previous comments roughing the shaft is a good idea.

            Hi there!
            Had the same issue, changed roller & gear - NG. After cleaning & lubricating the duplex-drive (espacily the part at the arrow) the duplex-jams were history.

              This little drive gear gets overlooked far to often and causes major headaches with duplex jams! Check this as standard these days when troubleshooting duplex jamming.
