    Re: riso rz 220 stretched mark on paper

    I have seen a few different causes for this. First is often the paper, does it happen with a different ream? Second, impression roller needs replaced. Third, one-way timing gear. There is a tech flash from 2005 about replacing the timing gear, see attached PDF. Good luck.
