Greetings all,

What machine, SEF or LEF, copy or print, are you referring to the line down the page just to the left of the image as shown in your sample?

[Larhal]

Dirty charge roller. Drum cleaning blade failure, Drum failure.

All I can see from your photo is the border of the image, you can replace the drum, dev, charge etc as many times as you want but you won't get rid of that

At the top of the images with the larger white area I can see 2 lines in the direction of the feed from each edge. Cant you see that? If it is not the 3 items you stated then what is it?

What I am seeing is edge shadow. It could be a skewed original. It would help if you had included what model you have.

To be honest no, all I can see is the border of the image.

How do you know what the direction of feed is?

He hasn't said!

I think it is a copy made on the platen glass with the platen cover or document feeder up. Look at the sample. There is large black mark that is wider at the bottom and a rippled black on trop long edge. That tells me that the original is not flat on the glass.

Correct, do not look for problems in the equipment, the original is placed on the glass "floating" and does not rest correctly on the exposure glass. It is not necessary to know the feed direction of the copy or the equipment model.

You may be correct. I could not tell the direction of the feed but that is what it looked like to me.

Also notice Marwan has not replied to this feed with any more information.
