When document passes through the ADF ,it passes through transperent sheet where document gets exposed to the CCD ,if dirt or dust comes in this path way
it gets no exposure generating thin line on the output,So cleaning the dirt will resolve....happy going.

There is a thin strip of glass that you will see when you lift the top feeder. There is most likely white-out on it.

When you use the top feeder, it doesn't use the large glass, it only 'rolls' the original document over this small strip of glass.

We have a black line down the center of all copies...


If the problem only happens on copies or sent faxes then no it is not your drum. There is something on your scan glass. My guess is you are getting the line on your copies when you run the original through the document feeder. If you get lines through the document feeder but not on copies made off the glass then it is a dirty scan glass. There is a thin glass strip where the document feeder feeds the original. Usually something like white out that did not dry smears off an original and ends up on this thin strip of glass. Scratch it off with your finger nail and use some glass cleaner to resolve the problem. The scan glass is about 1/2 an inch to an inch wide and will be on the same side of the machine that the copier feeds the originals in on

WHITE LINES ON FAXES SENT


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.

I have a black streak all on one side when i copy ?


If it is just when you copy and not when you print then it is a cleaning issue. Toner cartridge would cause the line to appear on copies, printouts and faxes. There is a piece of glass inside the auto document feeder that is probably dirty. Open up the document feeder as if you were clearing an original document jam. Look for a piece of glass inside the ADF, it will run the length of the document feeder. There is probably some dirt or another popular problem is white out. Clean off the glass with glass cleaner or alcohol and it should fix the problem.

Black lines when using copier


Lift up the document feeder and look for wite-out on the small glass.

If there is a sliding blue tab on the toner cartridge, move it back and forth 10 times. (cleans the charge wire)

Physically look at he drum, it should have no toner on it.

Line in copies that go thru feeder


Hi,

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
  • Glass cleaner
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 .
CAUTION: Use only glass cleaner. Avoid abrasives, acetone, benzene, and carbon tetrachloride, all of which can damage the scanner glass.
