Brother MFC 8440 Scanner has a line

Theres a line being placed on every document I feed thru the document feeder, but not when I scan it on the glass. How do I clean the document feeder scanner? Its seems very difficult to clean without taking the whole thing apart.

Whoaaaaaaaaaaa!!!!!!!!!!!!!!!!!!!!!!!!!! No need to da all that. Lift up the Doc feeder and look at the SMALL strip of glass, you will see a dot or something on it, clean w/alcohol. Voila taken care of. the dot ( pen mark, white out, etc...) makes a line because the document is Moving and that dot now looks like a line to the copier. :)

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.

When I Scan and PC prints, it comes out Perfect but When I use the Top Feeder to copy I am getting huge line(s) from tom to bottom. Is there a way to do a cleaning on the top feeder of my Brother MFC 7349...


Yes there is a way to get rid of the lines you are seeing when scanning from the document feeder.

Let me see if I can explain this in a way that you will understand?

Stand in front of your printer with it facing you. Make sure the document feeder is empty. Put your hand in where the paper would go, and pull upward towards you or to the left. This will open the top of the paper feed tray and expose the rollers that bring in the paper. You can use a brush to seep out the debris. This is not likely where you are getting the lines from though!

Where the lines come from are inside the flat bed area. If you open it, you will see a big piece of glass where the paper is placed to scan a document. to the left, you will see another small piece of glass and this is where the lights flash that scan the picture into the scanner. Try taking a slean lint free cloth and wipe the small glass area and the paded lid above it to get rid of any lines that are appearing on your documents.

Original document fed into top feed tray of mfc 7440N model come out with few thin black lines on the mid left of the scanned file. Scanning file from glass has no issue.


You need to clean the narrow glass strip on the left side of the machine when you open the cover. There is likely lint or something on this glass. This is where the auto document feeder pages are "imaged".

Brother MFC-7820N Printer--vertical lines


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.

Bad Scan Quality Using Brother MFC-7820N Document Feeder


Look to the left side of the flatbed glass for a thin strip of glass by itself. When you scan from the glass, the document stays put and the sensor moves across the document. When you scan from the feeder, the sensor stays in that glass strip and the document moves across the sensor. See what I mean? I would check the small feeder glass for dirt or scratches from staples or other flotsam. Also not a bad idea to blow out the feeder path with some compressed air to ensure the documents is handled smoothly. Hope this helps!

Could be a sensor in the ADF, or the hinge on the left rear of the scanner cover is broken.

Vertical black line in scan document not in copies through document feeder


Lift the lid and to the left of the main glass is a smaller glass; that is what scans during the feeding process. Make sure that it is completely clean; even a speck of dust can cause a line to appear. I took a lens wipe and cleaned mine and my line was gone.

Dirty scan glass

Clean slit of glass extremly well, it is a small slit rectangler section of glass before copy glass on the scanner.

Glue, Liquid paper are common finds on the glass in this area, While you have the lid up, clean white reference area (on lid directly on top of scan glass when lid is closed)

Print Problem - vertical lines


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.
