When I copy a document from the automatic document feeder the copy has a vertical line about 2 7/8 inches in from the edge of the paper. I don't know how to stop this line from showing up on my copies. This line does not appear on the copies when I copy from the glass panel. Thank you ecodock

Check your flat bed and Document feeder scanning glass need to be clean, if any dot or dust in scanning glass of document feeder it will appear a line, check this points first
1- Check printouts from computer or FAX if it is clean problem in scanning section
2- Check using Copying a blank paper using only Flatbed if it prints without any line its problem from document feeder Scanning glass
So solution is clean the Document feeder scanning glass using wet cloth, note careful about wet cloth switch off the machine and clean it

Hello mike,
You may have a fairly easy problem to fix, and that's good thing ! If the lines only appear when you use the document feeder then we can handle this. Please place a document on the platen glass and make a copy. If the copy looks good then we need to clean your "scan" glass. The scan glass is the small glass located to the left of the large platen glass. It's about 3/4" by 14",and will only cause problems when you use the automatic doc feeder.If it gets dirty then thin lines will show up. If indeed this is the problem then I have a test u can use that will help you Take a plain piece of paper. Mentally divide it into 4 squares and then simply write the numbers 1,2,3,4 on each quadrant. At the top edge of your newly formed test document place an arrow pointing away from the body of the paper, and it needs to point "UP".. Now draw an arrow on the test document that points to the left "lead " edge. Put your newly constructed test target in the document feeder and make a copy of it. Now, you KNOW how you placed the test document, so lets look at the copy. If you have lines only thru the document feeder, then look at the copy you made and notice where the lines are. Ok, now you know where the lines show up on the copy, so lets take your "test" document and compare them side by side.Once you have made this comparison, and can see where the lines show up, take the ORIGINAL test document and place it IMAGE UP (1,2,3,4) on the glass. This will point out exactly where the dirt is. By looking at the copy that has lines, and where they show up on the page, you can use the test page that is laying face up on the glass and compare the 2. BOOM !! You can look towards the small scan glass and find the dirt that is causing the lines. With your copier, IF you place a document on the glass then the scanner moves to "scan" the document. But if you use the document feeder, the scanner stays in one spot and the motion of the document moving ACROSS the scanner and is scanned like a bar code. If there is dirt on the scan glass then a line occurs instead of a "blob" as you would see if you used the platen glass.I hope this all makes sense (I tend to ramble) and I hope it helps you. You of course could have far more complex problems. But your description of the problem sounded like my remedy/idea might be just what you need. Take care and good luck. if I helped you please let "fixya" know. SPINAL

You need to clean the scanner glass. Also known as the strip glass. It is a 1 inch wide strip of glass that runs from the front to the back. Your documents pass over this glass when they are scanned. Some of the wax crayon probably smeared off onto the glass and now when you scan the scanner sees these marks as stationary and thus records them as solid lines. Just look into the scanner section where your documents are fed in or depending on model, some are just to the left of the large original glass.
Good Luck and thank you for using Fixya.

There are two scan modes when copies are made.When you make copies through ADF you originals go past small **** glass located to the left of the main exposure glass.Any small mark on this **** glass( correction fluid mark,ink mark,small scratch,dust particle and so on)will show as a line on your copy.So to get rid of these vertical lines on your copies you need to clean this small exposure glass.

there is probably a dirt spot on the scanner glass where the document feeds in. try cleaning the thin glass under the document feed cover.

Notice where the metal retainer beneath the glass cuts off the view of your document you wish to copy
and make allowances on your copy. Most printers disallow some portion of the edges of any document
for handling the transport of the document through the feeder, or in the cases of contact copiers, a portion
of the sheet as you have experienced, so that the edges need not be so carefully adjusted to avoid the dark
line in edge copied formats.

Format all documents so that you do not need to copy the portion excluded.

Sometimes this can be accomplished by reducing the size of the document.

If the lines are vertical (in the direction the ADF feeds, 11in long for 8 1/2 by 11) You can try cleaning the glass the scanner uses when it's using the document feeder. Pull up the top left part of the printer where the documents feed, there's a little rib in the middle of the side to help you do this, then simply pull up the assembly underneath with all the rollers in it, you should see about an inch of glass underneath and a centimeter long strip of white plastic on the assembly (this serves as the white background when feeding slimmer papers) Clean them both. I'd recomend any glass cleaner, just don't spray it in there, spray it onto a cloth.

First you need to determine if it's doing from both the  top and the glass.

1-assuming you are using the feeder to fax,copy or scan (the part that automatically picks up the paper) it comes out with a streak. Make a copy putting the paper on the glass and look at the copy. Does it have the streak?

2-lift the top and look to the left there should be a small 1inch glass, this is where it makes the copies from the feeder, is there a dot or white out or is the glass dirty? that's your streak, the paper is moving to make the copy,so the dot now looks like a line as opposed to making a copy on the glass it just sits there so a dot will stay a dot.

2- Clean with water or alcohol.

If the problem only occurs when using the document feeder, the problem is not usually caused by the drum. When using the document feeder, try to notice where the scanner (the light assembly under your scan glass)stops just before the paper is being fed. Some multifunction machines have a small piece of glass that is separate from the large scan glass and the scanner assembly stays parked underneith it as the original is being fed over it. Most likely there is something on the glass where the scanner parks as originals are being fed thru the feeder. When putting your original on the large scan glass to copy, the mark on the glass will only show as a spot, but will show as a vertical line thru the whole copy when using the feeder.
