    [Jamming] Ricoh Aficio MPC4500 Fuser Jam on 11x17 or Long edge Letter

    Hello, Ricoh MPC4500

    I have a paper Jam when feeding 11x17 or 81/2 x 11 ( Letter ) on long edge, short edge or Legal size is ok,

    I changed the fuser unit and the transfer roller from a working machine and the jam still present, see picture attached

    Some ideas ?


    Thanks

    What jam codes are you getting? & any recent SC errors in the log?

        He changed the fuser unit so that would include the stripper plate

          I will check the sc history, where can I look for the jam code ?

            The complety fuser Assy was replaced, and the problem was the same way..

              Something is not quiet right with the fault you described.

              You may like to post the first two pages of the SMC report to the forum.

                You're clearly not an engineer if you dont know how to check the jam codes!

                Enter SP mode= yellow, 1,0,7, hold down red stop.
                Then press copy SP, in the top box SP Direct enter 5990 & press # then execute

                    It took me a bit to understand the second picture, sorry about that. But based on the crease in the paper there, it appears that the either the paper is being overdriven before the registration rollers, or the registration rollers are not activating in time.
                    That only paper fed LEF jams that way is really weird, as paper width shouldn't have any effect in that area. Still, it might not hurt to clean the sensors leading to the registration rollers. And while I don't remember if there are any clutches in the registration roller drive at this very moment, you might want to check if there are any, and see if they have the red dust of clutch death on them.

                      I also was assuming that image 2 was the top of the fusing unit. After looking again I see that it is the bottom. Check the PTR unit. I have seen this where the paper will try to wrap around the transfer roller if there is a sticky spot on the roller or the assembly is damaged and not aligning properly.

                        I've had some strange creasing, and jamming, on these models caused by a warped right hand door. Might want to look into swapping one with another machine.

                          You really need the jam code to locate at which sensor is it setting off. The jam can be occuring at the exit or registration and is just stopped at the fuser that model overdrives a tinge causing the fold. That model had all sorts of jams caused by registration mylars, the duplex gate being warped, push switch failure, misreads in the tray size settings from tray sensor, ptr jams due to bent metal fins.

                          The fact that it feeds one way not the other could be misleading the real problem, even without the SMC you should get a jam code on the screen when you test it which will indicate which sensor is late/lagging.

                            Finally the was the indicated part Broken on the Duplex Unit, causing the paper to stop on the fuser

                            See attachment..

                            Thanks for you help..

                              If you changed fusers and it is working on short edge then it has got to be your lead edge registration.

                              Go into SP mode and go to 1-001-001 (Lead Edge Registration) or 1-002-001 (Side To Side Registration) and adjust those.

                              You can go back and forth between sp mode and copy mode by hitting the copy window at the top, then just do a blank scan and look to see where the borders of the grid that it prints out are. They should be evenly spaced on each side.
                              My guess is one of your sides is way to much over.

                              If the edge of the paper doesn't have a part of the paper where there is no image (or white area) then it doesn't have a place to grip the paper and throws registration off and therefore you get a jam.

                              Hope this helps!
