If the line is disappearing with a lower contrast, then it is definitely scaratch/glue/dust on the glass. Clean with Isopropyl alcohol. Dont use solvents.

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

copyvertstreaks.jpg

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...

This must be a vertical line and appearing at the same location on all drawings! Please clean the glass thoroughly. It must be dust particle sitting on the glass.

Getting vertical lines on scanned pages when duplex scanning on canon dr-3080c II scanner Only on duplex side of pages, though. Front page still shows up clean.


It is dust on the glass, clean it thoroughly. You will find it at the same location for all drawings and may get faded for lower brightness!

Wipe the rollers with a damp cloth thoroughly. Remove all the dust in the glass for a claen scan. The red color roller roller in the bottom needs thorough cleaning, rotate with hand gently (in power-off mode) and clean it thorughly. No solvents pls, except Isopropyl alcohol for cleaning

Everytime I scan, there are 2 vertical lines on appearing on the pdf file. I can't clean the stell roller as it's locked. can only clean the showing part.


Hello,
You need to get to the scanner's Glass area and what you will sometimes find is some ink or white-out there all it takes is a small drop or smear to screw things up. Clean the glass with isopropyl alcohol, then some glass cleaner and the lines will go away.

Good Luck!

How 'crisp' is the line? IF it is same thickness even at different contrast levels, then it is likely the scan module is affected. If the thickness varies, or has jagged ends, then it is dust on the glass or a scratch of may be a dust particle sitting on the scan module. This has to be cleaned.

Line going down page


Don't know if this is a solution per se but I replaced the glass bar (there is a part # on it) on the inside front of the scanner and still got a line. Then I played around with the back scanner glass and still got a line then I got in there real good and cleaned and when I scanned something it would show no lines until I saved the document then I got two lines. Thought it was my software going haywire but I did not give up, got some canned air and alcohol and cleaned the glass once again and blew out every part I could find and the problem resolved itself. Apparently the smallest piece of lint or dust, smudge or anything foreign on the scanner lenses will cause this line. But I love this scanner and I wasn't willing to give it up or pay $600 for a new one. Only had it a little more than a year. Persistence seems to be the key but check those little scanner bars and be careful, they are tricky to get out.
