Scanning multiple pages

When I scan multiple pages via the feeder, a solid line appears down the middle of each page. The line does not show up if I open the lid and scan each page manually.

Hi there

This could be one of many problems, i will tell you a few solutions that i know of, check the lid and see if there is a bulge in the middle of the lid (is the lid uneven in anyway?), if it is, i would suggest that you return your printer to the place where you bought it. This could also be a setting on your printer, the setting could be to scan a book or to scan two smaller pages.

If you would like a manual on how to sort this out (if the problem persists), please e-mail me at dustin_ellse@yahoo.co.uk

Kind regards and good luck

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.

Why is there still a line showing through middle of pages when scanning/printing via top document tray of toshiba e stuido 351c? I know who to clean glass area but not top tray.


Does this line appear when you try to print to the machine? Or when you make copies on the scan bed? If so, then you most likely have a mark on the drum unit. If not, then the **** glass that the document feeder uses is located to the left of the large glass surface, attempt to clean that and ensure that no mark or scuff marks are on the **** glass.

Line appears on scans and faxes


Do you use the document feeder when faxing and scanning? If so, the line is likely some paper dust, white-out, or other dirt on the thin piece of glass to the left of the main platen glass. Wipe that glass strip with a lint-free cloth, and if that doesn't work try using a little bit of alcohol.

If the line persists, or it occurs when you don't use the document feeder, it's probably dust somewhere in the optical portion of the unit, underneath the glass. If you want to take it apart, you can blow some compressed air around down there to scatter the dust or try wiping down the mirrors with a lint-free cloth.

Vertical lines about one half inch apart down center of the page when fed through the document feeder. No problem with fladbed copying or scanning.


If you open to document feeder and look at the glass when scanning via flatbed, just to the left will be a smaller piece of glass. That is the glass used when scanning through the feeder. Clean that glass as there is probably a couple of spots on it.

Scanning...


What do you mean scan? Is it from the printer to the computer? Or just plain copy? When you want to scan to the computer, you need a software that can scan multiple pages. HP's document feeder can copy and fax multiple pages, so if the software supports multiple pages scanning, then I'm sure it can.
