Why is there a line on the left side of my copy when I use the ADF on my Canon Image Clas D1150? It does not do it when the flatbed is used. Please help. Thanks, Joann

There are two possible fixes.

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.

Other Possibilities


If... Then... Vertical lines appear only when printing... Consider other printer-related topics such as toner cartridge, charge roll, photoconductor, transfer roll, or fuser.

I presume this happens when you are copying and not just printing from the PC. If so then you probably have tippex on the scanner glass. open the scanner cover and you will see two glasses. the left one is for the adf and the larger one on the right is for the flatbed. I bet you have tippex or something white laying on one of the glasses. To prove this all you need to do is make a copy from the adf and make a copy from the flatbed. The adf one will probably have the white line and the flatbed will not.

Simples...

Be sure the glass is clean.
If the Canon is anything like HP and you are using the ADF there is a thin strip of glass on the left end of the flatbed. This is where scans are read when using the ADF (Automatic Document Feeder)
All it takes is a tiny speck on the glass to cause lines on the copy. Clean it by spraying a glass cleaner on a soft towel and wiping

Do the black lines show up when you use the adf or if you make a copy from the copyboard glass. If the lines only show with the adf > there is a small **** of glass on the left side of the copy board glass > I would clean the slip glass with windex or a damp cloth..... Good Luck

Hi,
Your machine ADF is dirty or dust in adf glass please clean it by soft cloth and scane again its clear and sharp.
thanks.

When you say one sided scans are OK, are you using the ADF (auto document feeder) or the flatbed? Are you using the ADF for the two sided scan? What parts have you cleaned thus far? A little more info please?

thanks

Hi;

If you are only getting the lines when using the ADF , but not when placing the document on the glass then there is some type of debris on the scan glass.

This is a small strip of glass that is independent of the copy glass. This glass should be to the left or right of the copy glass. Just glean this well with alcohol or windex and try copying again from the ADF and see if the problem is gone.

Good Luck

Hello, my name is Steve,.
This is a common problem and an easy fix.
If you lift the ADF / top cover assembly up, you will see a small narrow piece of glass next to the flat-bed glass.

Ths is called a "Slit-glass". The only purpose is to read content from that point by the scanner, The Scanner will sit in the underside of it.

It is dirty. Wipe this with glass cleaner and a soft lint-free cloth. you may need to do this several times. Concentrate the part of the glass were this image problem is just by the orientation of the document you are installing with the direction of the document you are passing through the ADF.

It will take several attempts, but with each try, make a new test from the original document, unyil the problem disappears.

I believe this will solve your problem, Best , Steve

are you feeding in the copies from the Automatic Document Feeder? Open the top of the flat bed scanner and look to the left you will see a small piece of glass that is used for the ADF and then you will see a large piece of glass that is used for the flat bed scanner. Clean the small piece of glass used for the ADF and let it dry before trying to use the copier again. Test the copier and see if the gray line is still there. if you are using the flatbed portion of the scanner, clean the larger glass on the scanner and as before let it dry before trying to use the copier again and then test the copier.

You have to reinitialize the software. I will be back in a few minutes with the procedure. I have to hunt it up.
