Re: Line in copies that go thru feeder
Over time the automatic document feeder (ADF) will get dirty, occasionally causing vertical black streaks or lines in scans and copies .
Manual cleaning of the ADF might be necessary. Follow the procedure below to manually clean the ADF .
You will need the following materials:
Soft lint-free cloths
if you look carefully on the left side of ADF ( top feeder ) there is an assembly which u can lift , there wud be a set of rollers if u lift that part there would be a glass strip . u are suppose to clean that strip . While holding up the inside of the ADF, clean the glass in the location of the vertical streak with one of the cotton swabs. Try cleaning the glass first with a dry cotton swab. If that does not correct the problem, then moisten the swab with glass cleaner .
If the vertical lines or streaks still appear, go through the above cleaning process again, this time cleaning the entire surface of the ADF scanner glass.
and after this try the following steps as well .
Use only glass cleaner. Avoid abrasives, acetone, benzene, and carbon tetrachloride, all of which can damage the scanner glass.

When you use the flatbed the copy is perfect because the ccd sensor is under the glass cover and obviously is free form dust/ dirt.
On the other hand if you use the feeder the ccd sensor is located in between the roller assembly (not sure exactly for this model).
This means that the page is scanned by the ccd in the feeder, any dirt on the ccd will appear as a black line. I assume that you are feeding papers from the side and not from the top that is why you get a horizontal line.
A quick test to see if the ccd sensor is dirty is to feed the paper from the top side to the feeder. If you get a vertical line it is a proof that your ccd sensor needs to be cleaned.
The worst case is that the sensor in the feeder assembly has a tiny spot that is damaged and it is causing the black line.
So , first try the test, then open the feeder assembly, locate the ccd and clean it. Hope that this helps.
does this happen when printing? or copying? if printing check the fuser, image /drum unit What color is the line replace that image unit, if copying does it happen thru the doc feeder ? if so place on the big glass and make a copy if it goes away the its the doc feeder slit glass that is small glass use by the doc feeder, big glass not used by the doc feeder when copying or scanning
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
Sounds like you're having a problem with the automatic document feeder. The scanner is continuing to scan but the paper is not advancing as it should during the first part of the infeed. Check to see if something is inside retarding the path of the scanned document. Or it could be worn rollers in the ADF.
This black line sounds like it is definately coming from the ADF scanner glass. This is the thinner strip of glass that is located just to the left of the large original glass. You can verify this by making a copy from the large glass instead of using the feeder on top. If the copy comes out clean then it is definately the scanner glass. Just clean the glass well with glass cleaner and a soft cloth. This glass is only used when copying/scanning using the top automatic feeder
Good Luck and Thank You for using Fixya.
You have white out or some other white substance blocking your scanner optics. I am assuming this is a thin blank line. What you need to do is make a copy of a document with your machine. You should see the very same blank line on your copy that your customer is seeing on their received fax. Now take this copy and place it in the document feeder the same way you placed the document when you made your copy. Now imagine this document going thru the feeder. The strip that is blank will "match up" with the white out or whatever is causing the blank line. You just need to open up the feeder section where the documents go in to be scanned and look for the thin strip of glass that runs from one side to the other. Using the copy you made with the blank line, use it to see exactly where the glass should have something stuck to it and clean it off with a soft clotch with a little glass cleaner on it. Go ahead and clean the while glass while you are in there. Once clean you can close it back up and run another copy to insure that all the lines are gone.
Good Luck and Thank You for using Fixya.
The most common cause of blank (void) lines on a scanned document is from whiteout on the glass where the page is scanned when using the document feeder.
If there is a clear mylar sheet on the bottom of the document feeder, the whiteout may be there instead.
If there was dirt or a dark smudge on the glass (or mylar), it would show up as a black line, but whiteout is white, and shows up as a void (blank) line.
Hi sounds like you have a particle on the window in the feeder. What hapens is when the light scans the paper your copying the particle of dirt shows up as a line. Simply clean it with a soft cloth and mild window cleaner. . Thank you for using Fixya.com
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.
