      If the machine has been taken apart and put back together there is a chance the drum is nicked and damaged. Very easy to do on these machines when sliding the developer unit back into the machine.

        i took some pictures of a printed paper that gave me same problem , a lady who makes copies on that machine told me that the black marks doesn't appear every time just when she makes lot of copies or when they print a long paper ,

        it's been a time since it's been installed without giving any problem , i think it's something else !

          Transport ......
          Chain, sprockets or one of the transport gear.
          See if drum constant spinning or stopped at some point.

            I would look for anything that would allow the paper to lift off of the transfeer/detack assembly such as the detack shutting down or even a speed control problem that would allow the paper to overfeed. Also if the paper should stall as it is going through the fuser it would create the same effect but you really should get an error code for this one. But again make sure that drum is not stalling.

              I work on these, and the first thing I would do after a quick fuser roller inspection is pull the drum unit from the machine and inspect it. Seal or blade maybe. As mentioned, drum drive could also be affected by a loose allen screw.

                  The fusing cleaning roller only turns when the machine is reversing the paper from the fuser, that is why it does not always print. You can try scraping the streak off but anything you clean the roller with will also affect the oil the roller is impregnated with. If I was going to the trouble to remove the roller and clean it I would definitely just replace the roller. I have also run the earlier version of this machine without the roller removed and have had no problems.

                    had more or less a similar problem, turned out to be the cutting knife, on some point it came to late, not always. The knife cuts both ways, and during bigger jobs it did not return on time, and so it did slow-down the paper just for a fraction, witch resulted in such quality problem. After replacing the knife problem solved.
                    You could see on the affected prints, on the cutting edge of the paper that there was some minor damage, like it was torn for just 2-3mm

                        I would take the side covers off so i can see if there is a drum slip/stall issue. Also keep in mind that these have a waste toner bottle on the one side of it, that has an actuator that "vibrates" the bottle so that the toner remains even inside. This can also cause "weird" noises in the machine, that happens at odd times.

                        From your photos it looks like there is either drum or paper stall taking place. It does not seem to take place long enough for the machine to relise a jam condition, but long enough to upset the print image.
                        Press the GREEN button!!

                          Remove the drum unit and clean the wast toner recycle coil and check the around parts

                            UPDATE
                            i went to see about that problem that came back after a while of cleaning the fuser cleaning roller
                            what i noticed is this :

                            when i make copy on the machine it doesn't only produce black mark it also ignore about 5 cm of the scanned copy and in that part it makes the black mark
                            when i make a blank copy it doesn't produce anything !
                            before the copy end i hear a weird sound like something stop rolling

                            at this time all the copies i made came out from the bottom output
                            i tried top output and everything went very well !

                            i appreciate any suggestions to solve this problem .
