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.

I've cleaned the glass and still have a black line on the image


Scan a document in 300 dpi in full width. Check where the line appears in the image. For example if the black line appears at vertical position say 1900, then it means the dirt is at 1900/300 i.e., 6.3 inches from left. Clean the area thoroughly. Check if any pin had created a scratch in the glass. At different contrast levels, if the line appears different, it is definitely unclean glass. On the contrary, if the line appears constant at various levels of contrast, then it is possible that scan module is faulty.

When I scan pages in the computer using the document feeder a black line appears on the scanned pages. what can I do?


Try cleaning the PMT (Photo Multiplier Tube) - the glass tube that picks up the image. If there is a foreign body or dirt on the tube you will see a black line vertically (in the scan direction) on the page.

Vertical lines in image -- appears that belt is stuck


If the same image is scanned repeatedly, it appears like a line. Check if there is paper is moving (in high speed scanners) or the scan module is moving (in Flatbed scanners). If this is normal, all you need is to clean the glass thoroughly.

Xerox WorkCentre 4150, 3 vertical white lines in all feeder scans


the problem is in the scanner, open it up and see if you can find any smudges, and clean any obstruction, any ink, liquid eraser residuals, can cause this part to appear as lines on your copied faxed image.
dont concentrate on the printer this is a scanner problem

Vertical line in scanned image


This is because of dust sticking to the glass. Clean with isopropyl alcohol (rubbing alcohol) and dont use solvents. For emergency you can use your after shave but take care only to clean the glass portion!

HP 5610 scanner won't save image


I just need to understand the exact issue. It sounds like you are able to successfully scan, see the preview of the scanned image, and you initially save it. Then, when you go to open the saved image, you don't see the image you scanned but rather a "line". You've saved the image in a number of different image formats, but there's no difference in the result. It saves the scanned image to the location you want to save it on your computer's hard drive (probably My Pictures if you're using a Windows operating system).

Not sure what you mean by a "line". Do you mean a vertical line, a horizontal line, a diagonal line or what? Also, is it just a solid black line on a white background? Is it the image you scanned compressed into a smaller vertical or horizontal space?

Have to tried scanning both text pages and graphic pages? There have been issues where a document with both text and pictures has been scanned but when the scanned image is viewed, only the text appears. The pictures don't make it. The description of this specific problem is at HP.com.

I take it you don't get any sort of error message associated with this problem. Unfortunately, I can't find your specific problem at HP.com beyond the link I posted in the above paragraph. If you can answer some of the questions I asked, it might help me provide a better solution.

Thanks.
