Could be the drun cleaning blade folded over or marks on the charge roller, a bit tough to say with no scale against the image.

Are you saying that these marks are only showing up if you run from tray 1 LEF ? Which way is the paper being fed in relation to your image? I would say because the marks are duplicating that you either have a bad drum or fuser roller. Post an image of the counter sheet LEF ( long edge feed ).

Drum, charge roller, fuser roller are the possible problems.

Roll the paper up to match the marks in feed direction.

This is the size of the roller causing the marks.

All the rollers that can cause black lines have a different circumferance.

Is this the entire page or did you crop it? If it's the entire sheet then it's going to be the drum or fuser roller as suggested. Easy to tell if you do a quick visual on them.

I suspect the hot roller may be the culprit.

how doing this ? please help me about print counter sheet LEF and what is the LEF?

Long Edge First - The longest edge of the paper is fed through as the leading edge. Post the entire page so we have a size reference to gauge the placement of the marks. Have you actually looked at the fuser and drum surfaces yet?
