How many copies on m/c
It looks like your dev roller has a problem, change it or try cleaning with windex

"its 2200000 copies. its not the genuine toner but never had problem so far. What is Windex?
but when i change the potential voltage the lines come either in the middle or top or bottom."

I suggest using the tungsten (brown ) corona wire.
