Re: ricoh aficio mp w2400 , black mark at end of paper
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.Comment

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.NEVER ASSUME ANYTHINGComment

Re: ricoh aficio mp w2400 , black mark at end of paper
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.Comment

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 2-3mmComment

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!!Comment

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 .Comment
