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...

If the picture is taken vertically in EOS 400D SLR, there will be a black shade appearing in right side of the image. This issue was not there earlier. In recent times it started happening. It works fine...


I would be interested in seeing the dark image... check that its not the camera strap or some other part of your own pereson. Hold the camera UNDER the lens and take a vertical, noting where the camera strap is at the time. Perhaps put an example on one of the free photo sites and send us the link.
There is nothing inside a camera that should move and put a dark image on any pic.

Please rate my help++++Thanks for using FIXYA

Poor fax printout quality


I would say you have a bad drum / toner cartridge.

Stuff you receive with vertical lines is probably the sender's dirty scanner.

This is called "vignetting". To me it sounds like your lens hood isn't mounted correctly. If you don't turn it on all the way, exactly this will happen, because the longer "leaves" on the hood shadows the edges of the frame.
So, try to turnt the hood all the way on. You might have to use a little bit of force, as the hoods can be hard to turn sometimes.
Hope this helps!

Dark vertical shadows


No,you can't. This is very common. I bought a new tv and i noticed right away that it had the problem you are mentioning. I took it back for an exchange and the next tv did not have this problem...until a year later. Now,of course it does have this problem,but it is out of warranty.

I think they make televisions very poorly today.
