HP 3970 scanner

Whenever I scan a document I will get "Aqua" streaked lines across the about 1/3 of the document and that will also import into my photoshop. Is my bulb going or am I too trash the scanner? Bob Fowler

Black line on scans with neat receipts mobile scanner


Multiple lines appeared in every scan right after scanning a document from a credit card company that had those nasty adhesive strips used to attach credit cards.
First, I scanned multiple full pages to see if the problem would clear itself. After about 6 pages, I was able to identify the specific areas where the lines occurred on a document.
Next, I sprayed a tiny bit of glass cleaner (I used Sparkle glass cleaner, but I suspect any brand would work) onto an 8.5x11 sheet of plain paper in the area where the black lines appeared. NOTE: DO NOT SOAK THE PAPER, just get it damp.
Finally, I ran the dampened paper through the scanner. After each run, I would compare the result to the prior scan. As each streak was removed, I used a different piece of paper wetting only to address the remaining streaks.
After only a few runs, the streaks were gone (in my case).

Hope this helps!

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.

Hello I just figuered out this problem. When the paper is feed thru the ADF ( Automatic Document Feeder ) there is a plastic piece with a plastic film. Check to see if #1 that plastic film is clean and #2 That the Film is not bent and created a crease which is the line that shows when try to print or scan using the ADF. Hope this helps

How do it get it to scan from my printer to my computer. It says "Scan Error. Try scan from computer or see documentation. Press OK I did and it just shows the three options. Please help TY


Generally there are two ways to scan.
1. Your printer has a management program which controls most operations. On a Lexmark, it is the Lexmark Imaging Studio. Select scan there.

2. Your document software, Word, Photoshop, etc, can start the scanner. Usually under File, look for Acquire....Import....Twain.... Your printer/scanner should be listed. Select and start scanning.

If all this fails, you may be missing a driver, get them from your printers MFG web site.

good luck

There is something on your scanner glass. Clean the glass with glass cleaner. If this happens when using the automatic document feeder, open the top side cover where the paper feeds into. There is a narrow glass strip there. Clean that as well.

If this fails, the scanner head has a bad sector on the CCD and will need to be replaced. You will probably find that it will be cheaper to replace the printer entirely if that is the case.

Scanning document leaves streak down right hand side


Even a single grain of dust or a single strand of hair on the scanning glass will cause the scan head to perceive ink/image where there is none. Deffinetly try cleaning the glass using a good window cleaner, and a cloth that is completely clean, or even a peice of newspaper. If the black line remains, I would suggest taking it into a service center to have the scan head itself cleaned.
