    [Jamming] Low count IM7000 with frequent J015

    Good morning all.

    I'm pulling my hair over this one - an IM7000 with just over 300k pages on the total counter, with intermitent but frequent jams when leaving the fuser unit (J015).

    The machine is squeaky clean, still smells like new,no apparent binding when rotating the exit unit by hand.

    The jams appear to be more frequent the bigger the printjob.

    It jams from any paper tray (customer has preprinted paper on trays 1 and 2, and blank paper on tray 3 - all 80g normal weight).

    I'm now going to disassemble the fuser to check for anything that could give me a hint on what's going on, but any suggestions are welcome.

    Thank you.

    What have you replaced so far? Sounds like an intermittent sensor.

      Sorry for the delay, yesterday was an hectic day!

      I replaced the fusing exit sensor, and cleaned and lubricated each and every gear and wheel on the fusing and exit sections.

      Then I happened to witness a jam after about 300 pages of a test (before this I could only see them on the logging data, because the customer would only print long jobs between 8pm and midnight - outside of our working hours). Here's what I got:

      Then I proceeded to smear those wheels with high-temp grease (the only thing I had at hand).

      fjj2.jpg

      I then proceeded to print out 2000 pages without any jam - fingers crossed.

      I ordered a pair of new wheels. I hope I nailed it.

      Thank you. Will keep you posted.

        I don't think the grease on the rolls is relevant, indeed perhaps more tending to curl the paper, try instead to slightly increase the pressure of the wheels on the underlying tires.

            At least you have physically seen where the jam occurs. I am not a fan of applying grease to axles and wheels. I would ask for that pressure wheel in any case, although it is very strange. Also check the web unit for paper skew before reaching the fuser exit.

              At 300K I wonder if those stripper pawls have ever been replaced. All it takes is a slight hesitation of one of them going under the paper and you get a jam like that. That type is usually only good for about 120-150K.

                I have seen this also on brand new out of box IM7000 and IM8000 at a prison. changing out their paper helped some but I am seeing the rear lead edge corner folded over. they came out with a tech pub or something (not sure where i seen this) for folded corners and the issue was transfer power pack, but i have not tried that. I have aslo seen this on a couple of these at some schools.

                  I've had customers bend the exit unit entrance sensor actuator when removing jams. This will prevent the actuator from moving freely and it will log a Jam 15 in the SMC report.

                    Hope you have nailed it by replacing that pair of wheels, but if it doesn't fix it


                    try cleaning the Fuser entrance guide Plate if you haven't done yet ,most of the time its toner buildup on that and paper gets skewed from one side or another and that lead to paper jam in fusing.

                      You created this post about one year ago. Have you solved the problem. Me too facing this face already one year still haven’t solve. Today I found this in service manual. I’m gonna try in on my next visit and share the update here.

                          I'd love to help you, but I left the business one year ago and I no longer carry notes or other stuff related to copier machines. I'm not even sure if I solved the problem or if a colleague did after I left.

                          My last memory was that I had replaced the jam removal gate (the one with the stripper pawls) with another one from an old machine, and I believe the jams stopped - although the customer was irked about having a clearly old part on his new machine.

                          Good luck with that!

                            Paper jam for this model caused by cold papers. You can turn on the paper tray heater via sp mode. This model have built in tray heater. Go to sp5805-001, set to 2:continuous ON. GOOD LUCK
