I beg your pardon if this question has been addressed. My i860 had a leaking cartidge, now I have a series of marks on prints that appear to be coming from a roller. They are small dots and dashes evenly spaced down the page in a particular area. They start a bit down from the top of the print and end near the bottom. I've tried cleaning what I can figure out to clean but nothing seems to be helping. Can anyone tell me where to go from here?
