Vertical lines when scanning using automatic document feeder...Glass is clean

I have cleaned the glass. There is no problem when I lay a document on the scanner and scan that way. There is no problem printing. The only time that I always get vertical lines is when I scan using the ADF.

Any thoughts or suggestions on a fix?

    Did you clean both of the pieces of glass on the top of the ADF/flatbet scanner? There is a small piece of glass on the left that is used only during the ADF scanning/coping.

It is not in the glass. More than likely it is in the rollers of the ADF feeder. If you open the cover of the ADF feeder you can see there are 3 screws (! is found under another small cover furthest to the back of the machine. Once these three screws are removed you can left the entire ADF feeder from the unit. You will then be able to clean all the rollers. Do not use alcohol as this will dry our your rollers and cause them to eventually crack. Just use soap and water to clean the rollers. Then reinstall the ADF feeder assembly back on the machine.

I get a black line when scanning, ( not when printing)how do i fix it


This is commonly caused by a mark on the scanner plate. If you place your document to scan on the scanner plate (Lift the lid and place it on the glass plate) and scan or copy the document does it come out clean? If you feed the document through the Auto Document Feeder doe the line appear?

If when place on the plate it is clean but fed through the ADF there is a line, then when you lift the lid on the scanner you will see a narrow glass plate at the end (Normally the left end) of the scanner plate. Give this glass a clean and your mark will go away.

If the scan or copy is lined when using the Flatbed scanner and the ADF then the problem will be in the scanner lamp which will be probably uneconomical to fix.

Try scanning a few documents in full size mode (scannerrs maximum), If you observe a line in the same location in all images, you can conclude that there is either a scratch in the glass (due to stapler pins) or dirt stuck firmly. Try cleaning with Isopropyl alcohol. For absolute emergency, you can wet a cotton bud in after shave and clean the right spot, take care not to touch any other part other than the glass. If glass is scratched, you need to replace it.

Black line in paper


On what operation are you receiving the black line in your paper?

This problem usually appears when you try to scan or copy using your ADF (automatic document feeder).
To remove this black line in your paper, clean the ADF platen glass in your printer and do as well in the flatbed scanner glass. This ADF platen glass can be found right below where the documents in the ADF goes through. Its a glass about 1 inch in with and beside the flatbed scanner glass (the one where your documents is lay down for copying and scanning. Dried ink or paper residue sticked in the glass can cause this line in the paper. Clean it with a a clothe and spray some windex on it.

Good luck!

When i make copies a line appears on the right side of the copy. This problem does not occur when i scan to copy only when the document runs through the feeder


Clean the document feeder scanner glass. This is the much smaller strip of glass that is to the right of the large main glass. This strip of glass is used ONLY when using the feeder. So if you are getting a dark line when using the automatic feeder but not when laying a document on the glass then just clean the strip glass. 100% sure this is your problem. You may need to clean it several times as I have seen stuff get stuck to this glass.
Good Luck and Thank You for using Fixya.

You need to inspect and clean the narrow glass and the white reference bar that sits above the narrow glass. Scratches, whiteout, and debris will cause the lines on scanned documents.

Lines on my copies


As the page you wish to copy goes through the document feeder, it passes the scanner as well as a white plastic band that the scanner "compares" the dark writing or data on the page to. If this white plastic band is not very clean, the scanner reads the dirt as if it is part of the image you are scanning. Try cleaning the band as thoroughly as possible, as well as the small piece of glass to the left of the larger glass on the flat bed scanner. Make another copy to test your results.

Hope this helps!

Canon MultiPASS F50 won't copy but will scan


Does the copy function work if you place the document to be copied on the platen (open the cover and lay it on the glass)? If so, check the area to the left of the platen. There should be a strip of glass with a clear plastic cover over it. This area is used for scanning when feeding paper through the automatic document feeder (ADF) from the top. This area must be clean. If this area is clean and clear, it's possible that the scanner element (below the glass) is no longer going all the way to the left when using the ADF. This would be a problem that would require servicing.

Problem when scanning


If it is under warranty, contact HP.

Believe it or not, there probably is something in your scanner. Often times it is a very small piece of dust/fiber. If you are using the document feeder, the check the small piece of glass as the scanner bulb remains stationary and the paper is fed by. If you are laying the paper on the glass and scanning, then you will need to look at the scanner bulb itself. Run a scan with no paper and see if you see anything. If not, you can try to take it apart and clean the bulb (but do not touch the bulb with your bare fingers), with a light wipe of a tissue. If after cleaning, it either moves or goes away, then it is dust related. If it remains in the same position on the page, then there is a scanner bulb problem.
