A line appears after scanning a page. - Canon DR-9080C Path-Through Scanner

If dirt sticks to the scan module, it will be scanned continuously and appear as a line in the output. Clean the glass with Isopropyl Alcohol. Dont use any other solvent.

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,

This is usually caused by something on the image scanner glass. Check out this page.

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.

I have the exact same problem. It was there since I first bought the MFC-7840W.
Vertical line appears in scans using the automatic document feeder (ADF).
Vertical line does not appear when scanning single page (placing it directly on the glass -- i.e. not using the ADF).
Cleaning the glass strip for the ADF (or the white pressure bar overhead) does not solve the problem.
The problem does not occur with copies using the ADF (using the COPY button which is basically a scan and print). This would suggest that dust and dirt is not to blame because that would also appear on the copies.
But since I believe a copy is basically a scan plus print, they should be using the same electronics -- a hardware problem on the scan would likely appear on a copy also -- there is some difference between how they accomplish this.
It's definitely not a software issue since it occurs on all versions of Windows and Mac OS X (and multiple computers). It also does not matter whether I "push" the scan to the computer by using the scan button on the MFC... or "pull" the scan from the MFC using the Brother Control Center software.

This sounds like a dirty scanning glass in the adf feeder. clean the glass with a soft cloth. if this doesn't solve the problem, there might be dirty optics under the scanning glass.

Why do I have to replace anything on this printer when it's only 6 months old!

Check the glass of the scanner. It may have some stain over it.

Hello,

A dirty glass base can cause ‘spots’ or blemishes to appear on your final printout. Additionally, if you had some sort of opaque liquid that may have transferred on to the glass base from a previous operation. But the majority of the unwanted vertical lines are generally caused by either a dirty or damaged print roller or faulty LEDs in the Scanner Module.

To separate one from the other you have to check the following:

Do you only see the lines with a Scan operation?
Do your print jobs print fine without any unwanted lines?

If you only see the unwanted lines during a Scan operation, then most likely you have a fault/dirty/obstructed LED module.

If you see the unwanted lines with all print operations (Scan, Print and Copy), then you most likely have a worn out, damaged or dirty Print Roller.

Hope this helps…

Clean the ADF roller and the far left hand side of the glass, the small strip outside the 'main' panel.
