There are two possibilities: 1) The scanner sensor has a dead pixel, or 2) There is a particle covering a pixel of the linear scanning sensor array.

If you are up to it, open the scanner carefully and clean all the optics while you are at it. So the back of the glass cover, the mirrors (carefully!) and then the sensor. You may want to use a duster spray can (I think Office Max or Depot carry those) and dust of the sensor and the mirrors instead of using a soft cloth. If the scanner uses first surface mirrors, then one can very easily ruin the mirror coatings and it will be full of scratches from the dust particles when you wipe them! If they use regular mirrors (where the reflective coating is behind the glass) then it is safe to use a cloth.

If that does not get rid of the black line, then you have a dead pixel in your scanner sensor and you need to buy a new one.

There may be a way to tell whether it is a dead pixel or a dirt particle on the sensor. If you open your scanned image (or plain white paper image), magnify the image and see if the line is exactly one pixel wide - that would point to a dead pixel. If it is more than one pixel wide and the scanner did not do an interpolation then it is a dirty sensor. To make sure, scan with the maximum intrinsic resolution (chek the scanner's manual for that), so you don't interpolate between pixels. I am still not sure if that also applies to color scanners, they have a color filter over the linear detector array. It may depend on how the pixels for the color coding are arranged. But then I would expect an 'off-color' line, not a black line. If it is a black line and if it is more than one pixel wide, I am sure that a dust particle is the reason for it.

Good luck, Stephan

THERE IS A LINE ON THE RIGHT SIDE OF THE SCANNED COPIES, CANNOT SEE ANY OBVIOUS DIRT ON ROLLERS


Look at the glass strip through which the documents are scanned. Even a tiny spot there results in a dark line along the scanned image. Often such spots come from scanning a document with corrections made using the white correction fluid :)
The users manual (UM) describes the cleaning procedure on pages 61-62, you can get the manual here:

I get a black line on my faxes or copies - i have a sharp UA260. i even cleaned the roller and scanning glass per manual.


Your problem is most likely something stuck on the scanner glass that is blocking that part of the scanner glass, causing the black line down the sheet. Open up the machine and remove the roller to get to the scanner glass. Look very closely at the glass and see if anything is stuck to it; even a small speck might cause this problem. The black line on the page will be the same place to look on the glass for any . If alcohol on a cotton swab doesn't help, try using a small piece of paper and wipe off the glass with it. You can also use a fingernail to scrape off that part of the glass. Don't worry, a fingernail won't harm the glass.

Hope that helps!

Wide black line down page


open the document lid. Check to see if there is white-out on the glass platen where the document rides across the scanner. Some units require the white roll to be taken off.
sometimes a black mark on this platen can leave black streaks on copies made on this machine, and even when they send to others.
Try to clean the platen glass.
