    [Jamming] RICOH mp 6002 SP, mp 7502 SP Doc Feeder Jamming

    we have installed three brand new units and all three are having intermittent Jamming in the doc feeder. Anyone else seen this problem and if so what was the solution?

    What jam locations are they giving?
    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.

      All three have been jamming at the registration sensor in the DF. We are trying buckle adjustments, but without any success. We've checked the one way bearings, but all seem to be ok. Sensors are clean (machines in place less than a week)

        To repeat TonerMunkeh's post: What error/jam codes are you getting. They will tell you where the problem is occuring and/or what sensor/switch is causing the problem. It is not perfect but it will help
        Testing 1-2-3, testing, testing. Is this thing on?

          Jam code 006 which refers to the paper reg sensor which we have tried to fix by replacing it. But continues to give the same code

            The same problem for 3 machines? Are the document feeders properly mounted on the machines?

              Check for a Firmware update unusual to have the same problem on 3 machines its usually the firmware

                      Do they work in free run?

                      Sounds enviromental (Poor originals) or firmware. The chances of all machines having the same problem are very slim.

                        Glasses? Not sure if your making a joke I didn't quite get or if I just don't understand the question. If serious please explain? Not sure what you mean.

                          Replacing 6001's with 6002's. the originals were not an issue with the previous version.

                            Check the idle gear on the feed belt drive shaft. The one which the feed belt shaft docks into. I have found on a number of new devices that the idle gear which is supposed to be stuck in position is actually not, and slips intermittenly causing a jam. It all comes as 1 piece in the service manual with the one way bearing on the front, and the idle gear pressed onto the shaft. You will need to remove it and turn it by hand, only way you can tell if it's stuffed or not
