    With an explanation of your jamming problem as limited as you provided there is probably not much we can offer you to help. I don't know if you are looking to solve a repeated jamming issue or if you just need help to clear an existing paper jam that won't seem to clear. If you can manage to clear the jam and you can make single sided copies with no problem but you get jams at the left side door when making duplex copies, there is a common cause for this. On the left door assembly, there is a gate in the inverter section that has a small white plastic holder that keeps the gate from being able to move forward (toward the fusing unit / exit). This piece over time becomes brittle and breaks. It is held in place with 1 screw (screwed in on the front upper side of the left door). If this part is broken, the gate can then move forward causing the jamming. You can either replace this part (part # 019E48481) or come up with a more creative way of keeping the gate from being able to move forward.

      Hello,Thanks alot for your reply and sorry for my bad english and lack of informations. It's a repeated jamming issue, to reply you, the printer works perfectly with single sided copies, but when I print double sided copies, very often, I can print 10 copies maximum then a jamming problem occurs.How I can see that the piece is broken ? IfI take you a picture, could you confirm me that is this piece which is the cause of the jamming ?Thanks a lot for your help...

        PS : I saw on Ebay that someone could provide me the piece, but I have a doubt with the name "PAD SHEET", is it the good part ?http://www.befr.ebay.be/itm/XEROX-PA...-/250554566005

              Well, there goes my bright idea. Your gate holder looks to be in good condition.

              Next step in troubleshooting this problem would be to check over the paper path that is only used when using duplex. Check the condition of rollers, guides and sensors. Pay close attention to any sensor actuators in the paper path. Sometimes you can have the tip of an actuator broken off that upon a quick inspection looks good.

                Erok,Are you sure tha the white part is good ? because as you can see the plastic seems to be old, and could explain that sometimes it works and a few copies later not.... no ?The problem is that I don't really know how the paper is feeded, I can take some pictures to who you the sensors, paper path etc... I need some help to know which acuator I have to check and how I can tell It's good or not.regards

                    Its hard to tell what is causing your problem from my side of the internet. I'd have to see the machine in action to have a better idea.

                    Since the jamming is only with duplex, you would need to learn what path the paper takes during duplex mode that differs from simplex mode and then check all paper guides, sensors and gates that are involved.

                    I only work on the WC version of this machine (that has an attached scanner with full display screen, the workcentre 7345). Is there a way to find out what fault code is being generated by this paper jam? That might help pinpoint the problem. Can the fault codes be seen by logging on to the machine over the network using a PC?

                      Hello Exok,
                      Sorry for my late answer.
                      You're right for the path but I don't know where the paper need to pass in duplex mode, and I have no experience to check paper guide sensor and gates. I can take pictures in order to help me to check them.

                      I only have a message from windows which indicates that there is a paper jam, but I don't know how to have codes by logging on the machine. Does it exist any tool that permit to log on the printer ? I suppose I have to connect on the printer directly and maybe there is web based page which permit to see error code ... ?

                      thanks a lot for your help, I really need to solve this problem...

                        If you really need to solve the printer problems buy a service manual, only 15 bucks, and read how to see or print error codes. Also there is described how to check sensors, rollers, etc. SM is a starting point to help you because we will talk about same things.

                          Hello Adriansto,
                          I have downloaded it... I'm going to read it if I can find some informations about jamming...

                          regards

                            Go to chapter 6 and read about how to see faults log history. Then follow procedures from chapter 2 for the every faults you see in history. I think your manual had a chapter named ' Theory of operation'
                            If so read it carefully.

                              There is an explanation in order to enter in service mode. There are a lot of tests ! I see that there is a section for "Media Jams and the paper path".

                              I also forgot to mention that sometimes (only when I print two sided) the paper is folded corner, and after there is a jam, and the paper is often bent when the first side is printed, so when the other side is printed sometimes the jam occurs.
