LEXMARK E250DN/ Feed issues

[cucuklotz]

Hi,
As usual I have limited experience on this Model,The machine feeds 2 sheets instead of one with the second sheet having the last line of first page on it.It does this frequenly enough to be a problem.I cleaned feed and made sure cassette ok.I cant see,m to find any place that sells the feed tires. Any help is welcome.
thanks Andy

More details aperfeeds fine when multi copying ,double sheets feed only on single prints and last print of run as though it overfeeds and problem dosnt matter when on multiples.
