Black line when scanning though auto feeder

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.

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

Hi walt_latimer,

If when you copy or fax something and it has a black line running down the page, it is often caused by a dust, dirt spot or mark on the glass where it is being scanned. The easiest way to resolve this is by cleaning the feeder glass that reads it with a clean cloth.

Hope it helps.

Thank you for using FixYa.

there is a mark on the glass where it is being scanned.

If you are using a doc feeder then you need to clean the glass that reads that.

probably just a small mark on it.

if this helps please leave me a rating if not let me know.

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.

Lift the auto feeder cover and clean the narrow glass that the originals are scanned across...sounds like you have some dirt there -maybe correction fluid? That's the most common.
Please rate me :)

lift the auto feeder and clean the scanner glass that your pages scan across -it is dirty. You can make a copy afterward and this will tell you if you have solved the problem.

clean the thin strip of glass located under the document feeder with something non abrasive

If you lift up the lid on your scanning device you will notice a glass strip about 1 inch thick and then the large area of glass used for flatbed scanning. The 1 inch strip is used for ADF scanning. Because your papper is moving across the glass strip, any dot, smudge or scratch will affect your scanning and cause verticial lines down the page. Sometimes the dot is not visible to the eye. Get some glass cleaner that has alcohol in it and thoroughly clean the glass strip and it should solve your problem. If it turns out to be a scratch on the glass then cleaning won't help.

sounds like you need to do a head cleaning. go to control panel on computer and click on faxes and copiers. right click on the printer you are have problems with and there will be a head clean and nozzle check choice run through those.
