Top Feeder scanner leaves a line along the copy

Hello, Our 3055 has started leaving marks on pages as they are scanned. The marks appear to be 1-2 inches from the fight side of the page. This is only occurring when using the top feeder and not the flatbed. Any ideas?

This Is good for all "all in one machines"

There is a dot on the 1inch glass, when making a copy or faxing or scanning it makes it form that part of the glass. It shows as a line because the paper is moving as it is being scanned. clean the glass w/ alcohool. Sometimes it is hard to see because the background is black and the dot may be a pen or pencil, but it's there.

try to take the copy and lign it up w the glass and look where the line is you might see it htere.

Copier leaves a black line when printing through the top paper feeder. Ok coping from the flatbed

When copying from the feeder the page is fed across a fixed point at the head of the flatbed. Any dirt etc on the glass at this point can present as a dark line running vertically down the printed page. When copying from the flatbed, the scan head is moved down the page so any dirt on the glass will only appear as specs. Try cleaning the glass, especially at the head of the flatbed where the feeder is loading the page to be copied.

Scanner leaving black streaks

There are two possible fixes.

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.

Other Possibilities

If... Then... Vertical lines appear only when printing... Consider other printer-related topics such as toner cartridge, charge roll, photoconductor, transfer roll, or fuser. Contact Lexmark Technical Support. Vertical lines appear when you lay the page on the flatbed...

Copies leaves lines when put through the feeder,but not on the glass .......have cleaned and sprayed air can everywhere I can think of The Hp Printer is HP 3055 All in One printer

Most likely a fax has been sent or a page copied with 'white out' (Liquid Paper), still wet on the page. As the page feeds over the scanner, (a narrow strip of glass that runs across the width of the page along the feed path) the wet liquid paper comes off on the glass as a thin line and dries. Thereafter, when copying, scanning or sending a fax, the scanner light does not go through the liquid paper streak and the result when printed is a thin vertical line that runs the full length of the page.

If this is your problem: follow the path that the paper travels when sending a fax or making a copy, until you find the scanner (narrow glass strip). Take a clean, soft cloth and a small amount of methylated spirit (or white spirit) and remove the now dried Liquid Paper from the glass. Clean the whole strip ensuring that the glass is left clean and dry.

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.

Lines on Outgoing Faxes and Copies from Feeder Is there a way to clean the doc feeder scanner? I have a big line going down the center of the page when I copy or fax from there. Thanks!


If you lift the top of the unit so that you can see the scanner glass and clean the surface on the left side and the very end of the scanner you should be ok. The sheet feeder runs the pages through the feeder and down to the glass at the end then back to the feeder and out to the stack of pages. If you try to scan anything with wet ink, highlighter, marker, etc some may come off on the glass and cause the lines to appear. Just use windows on a paper towel, not sprayed on the unit.

I hope this helps, if so please rate our solution.

Facing copying problem from scanning section

Although you didn't specify the scanner model, this solution should work.

If the scanner has a top feeder, open it.

You will see a thin strip of glass, either to the left, or right of the large scanner glass.

There is most likely a small spec of ink, white out, etc on it.

Clean the strip glass with rubbing alcohol and the line should go away.

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.
