      thats a mouth full for a non printerguide^^
      i checked within the field manual, removed the just the 2nd transfer-roller an re-seated it. it is on the right-hand side machine upon opening the latch, the "middle" roller up on the spring-bearing bigger unit.(hopefully)
      did not look broken, it is rolling freely:-)

      picure follows as i have to leave for an customer emergency.

      thank you very much:-)

        The roller is usually fine, it's the spring loaded post on the right side that breaks and you usually won't see it unless you lift the assy and see the while right side comes up.
        Wish I had a pic.
        It's the right side of the pressure cam. Rotate the cam and look for unusual movement and broken parts.
        We know a thing or two because we've seen a thing or two.
        The medication helps though...

          Yeah, it's not the roller itself but the mechanism that presses it against the primary transfer belt. In my experience the rear side breaks. =^..^=
          If you'd like a serious answer to your request:
          1) demonstrate that you've read the manual
          2) demonstrate that you made some attempt to fix it.
          3) if you're going to ask about jams include the jam code.
          4) if you're going to ask about an error code include the error code.
          5) You are the person onsite. Only you can make observations.

              Not with the 20lbs of spring pressure unfortunately.

                As a temporary, I drilled the broken off shaft #37 (coat hanger size), drilled the bracket again #37. Then epoxied in a length of coat hanger wire. I would have liked to let the epoxy cure longer, so the resulting piece wasn't quite as well aligned as I might have liked, but it was mostly indestructible. I might still have it around, someplace. =^..^=

                    Thank you Sir for contributing to my innocent stupidity by providing an affordable solution to one of the "hidden beauty mistakes" my Dumpster-Girl had hidden under her weighty belly

                    as i am an r/c guy as well i do have experience with shredded wheel-hexes my favorite cure: epoxy+ metal-rods!

                    hopefully my skills will be enough to give your fix a shot:-)

                    thank you for posting, very much appreciated!!!!

                      Good thread to read. At least you returned us the faith that someone untrained and obviously inexperienced has the thinking and will assist to the best he can in truly respectful way. Wonderful!

                        I've noticed that you keep a database that's complete with pictures of your fixes/solutions. That's the way its done as its hard to remember all of it and you can refer back to the information if/when you run into it again. Props.

                          There are plenty of tricks to keep these machines running. Rebuild kits for the units.
                          Humor yourself and get a quote for one of the image units. Also check what a new replacement is worth.
                          Pricey stuff.
                          You might be supersized that there are plenty of them in the bin somewhere out there.
                          Awesome printer to have for printing tens of thousands of prints a month.

                          Please take pics of your repair and then print some half-tones from service mode.
                          Print them at 150 out of 255 and post that.

                          What are you going to do with the machine, home printing use?
                          Great of you to bring it back to use.

                          What is the meter count on the machine?
                          Check the consumable life.
                          Whatever

                            You have an advantage on me: I had other calls to get to, and I could only let the epoxy cure ~60 minutes. You can get it aligned perfectly and let it sit the full 24 hours ... even better 48. Yes please post your results. =^..^=
