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 ).

[salmandol]

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

[nmfaxman]

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?

yes . no problem on drum and fuser surfaces exist

Roll the paper up so the lines meet and this will give you the diameter of the roller your looking for. Stop the page before getting to the fuser and you can see if it is drum only.

I would look at the mag roller in the dev unit. Plus i would aslo run it with the side door open to see if the image appears on the drum during cleaning. ii would change mag roller , charge roller and poss hot + presure rollers

good luck

Going by the distance between the marks, I would say that you have a bad fuser roll. Check your fuser hot roller for the same marks on your copies and change the roller.

[teebee1234]

I measured the image on the screen and roughly adjusted it to letter size, the distance between the marks corresponds to the charge roller diameter. Clean it or replace it. More than likely the entire thing needs a pm. The only other part that is close to that diameter is the fuser cleaning roller but then you should have those marks on the backside of the print (and not as consistently dark).

[jonhiker]

if the lines stay in the same pattern, but the pattern shifts with each copy, then it is probably a drum. how many copies and when was the last time it had a PM? you might want to do the whole thing, pcu, developer, fuser, & transfer belt.
