issue resolved by cjarn after lifting the top of the scan tray, i looked on the top part of the scanner where it feeds the paper to the computer it was clear. but the other side onthe area directly under this had a couple small black lines on it.Ink or toner ? that is what made the continious line possible. A q-tip with some alcohol took the black off. now the scanner only sees the paper copy with no line. result> clear copy with no line. problem solved!
