    I have the same problem with vertical lines in scanned images. Cleaned the glass. The HP 1315 does not have a feeder, so that wasn't the problem. Any more thoughts?

    We cleaned the glass. Lifted the feeder but there's no glass there to be cleaned. What else?

    This is what Canon tells me and it worked. The key is popping out the plastic cover covering the scan glass literally a thin line of glass on the left/short side of the machine if you are facing the controls, beside the platen. Here is what Canon sent me: Thank you for contacting Canon product support. I understand that there is a vertical line when scanning and copying from the ADF of your imageCLASS MF4570dn.

The common solution on this sight to this problem on any copier seemed to be simply clean the glass. I first cleaned the glass on the bed...no help. Then I lifted the feeder and discovered a portion of the glass under that as well. Once it was cleaned the lines disappeared!

I saved $$ on a useless service call for a simple, easy to fix problem thanks to this site!

Ok
i figured out a great way to fix this
i took a sheet of paper and numbered it 1-50 acros the top
i then scanned it and printed it out.
i then held it up to the the window for scanning (for batch scanning)
i was then able to find the miniscule specks that casued the lines.

SOURCE: Vertical lines through scanned images.

You should clean the small glass under the top lid. Chances are there is some white out or ink or mark on the glass. Look carefully because usually it is just a small dot>

Black vertical line on scan


Usally this is due to dirt accumulated on the glass surfaces of the scanner.
Make sure that both glass windows inside the scanner are clean.
Next step is to clear both CCD's (read heads) but in this case you need to disassemble the scanner.

Scanned images have lines through them


If the lines are vertical, the glass may need cleaned, or the unit itself may need a good cleaning. Horizontal lines usually mean the machine itself needs a good cleaning as the scanning apparatus is not moving smoothly.

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.

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.

Scanner leaves lines like watermarks in an image


The scanner must be cleaned internally.

If you get same problem after cleaning the scanner, then this is caused by a defective sensor array (the device that "capture" the picture) inside the scanner.

Vertical lines in scanned documents


Scan glass has muck on it, needs to be perfectly clear, it is just in where you feed originals.

Scanned image has a line running through it


This could be one faulty sensor pixel or a speck of dirt on the scanner bar. It might be worth opening the scanner and carefully dusting the bar with a camera cleaner aerosol.
