Your ADF is not feeding the paper straight. The black line is the gap created when the edge of the gap
has a gap along the edge.

* Adjust your feed bars so that it holds the paper tightly centered to the ADF.
* Check that there is not dust in the feed path of the ADF roller and it is clean.

Scanner leaving black streaks


There are two possible fixes.

Download the latest firmware update by CLICKING HERE

The following is provided by courtesy of Lexmark:
Problem Vertical lines; Auto document feeder scan anomaly; ADF scanning problem; Scan issue; Scanner issue; Visible line; Streaks show on page; solid line down the page; Top to bottom line; Smudge runs down the page; Opaque line; Broken line; Bar all the way down the page Solution Overview

This article provides the self-diagnostic steps necessary to evaluate top-to-bottom streaks that appear when copying or scanning.

Important! This is seldom a scanner hardware failure.

The main reason for this anomaly is debris or marks on the scanner glass that is used for Auto document feeder (ADF) page scans.

Printed or Scanned Page Illustration

Who should consider this article?

Any user of an MFP or All-In-One printer experiencing the following symptoms:

  • -Vertical lines only when using the Autodocument Feeder (ADF).
  • -Observed with any type of scan job (e-mail, ftp, solutions, fax).
  • -However, normal expected output when the page is scanned from the scanner flatbed.



ADF scan behavior

Think of it this way:

  • -The page is pulled from the ADF.
  • -The moving page slides across an ADF-designated portion of glass.
  • -The image sensor, which is located under the glass, reads and interprets the moving page's contents.
  • -Contamination on this ADF glass is seen by the image sensor for the entire length of the page.
  • -The image processor interprets the image sensor's repeated capture of this contamination as a vertical solid line.
  • -Any ADF scan function now exhibits a vertical line.

Suggested Diagnosis and Fix




Step Action 1 Locate the portion of the glass designated for ADF scans.
HINT: The glass location differs by model. This area is often separate from the scanner flatbed. Please reference User's Guide for more information if you are having a difficult time locating this designated area.
2 Perform a visual inspection for any of the following recurring culprits:

  • -Clear adhesive tape
  • -Glue
  • -Ink pen
  • -Paper
  • -Marker
  • -White out
  • -Staples
  • -Environmental dust or dirt
HINT: Ink marks can be especially hard to see and almost translucent at first sight. However, the image sensor (CCD) registers them as a mark. 3 Use a clean, soft, moistened cloth to thoroughly clean and remove any marks or debris. 4 Inspect the underbelly or underside of the ADF for any marks or debris. 5 Perform another scan to see if cleaning the glass alleviated the issue. 6 Repeat the procedure if a vertical line still appears.
Remember! Printing and scanning from the scanner flatbed work fine.
7 This time, place an intentional mark on a blank sheet of paper and take note of its location. Now place that sheet of paper in the ADF and make a copy.
8 Evaluate the distance of the vertical line to the your mark. 9 Inspect that area of the glass for further debris or marks and clean as necessary.

Black vertical line prints on the right side of every page.


Good Day Tkidwell!

Better check and clean the ADF platen glass and the flatbed scanner glass.

Use a lint clothe moistened with alcohol or water and gently wipe the dirt in the glasses of the ADF platen and flatbed scanner.

You can also try cleaning the roller by performing the deep cleaning.

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!

Brother 7820N has black vertical line when using ADF


It's the same scanner ccd, after you make sure the narrow scanner window is clean, you need to power down the machine and power up again so it will calibrate to a clean window, if it has a scratch like from a staple, you will need a new glass.

Black vertical lines on faxes sent using auto document feeder


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.

Taking apart the flatbed


First remove the electronics from the rear - 3 screws at top.
Under the black plastic is 3 screws per ADF hinge - remove. Lift ADF up from the base.
On each side is a screw that may be hidden under a black piece - slide it down and take out screws.
Remove screw from front left side. Remove 3 screws from top near glass.
Remove control panel by levering forward and up - disconnect cable. Remove screw underneath.
Lift top section straight up and off.
