Black vertical line on scans

MrsPhilli — Tue, 10 Sep 2013 22:45:39 GMT

I have an ImageClass mf4370dn and it suddenly has a black vertical line that is printing when I scan a document. It does not show up when I copy it. How do I repair the equipment? Thanks!

Hi, MrsPhilli!

If the line that is being produced only occurs when using the Automatic Document feeder (ADF) and not when making a copy via the platen glass, the issue is commonly due to a small mark or debris on the scanning glass area that lines up underneath the white vertical ADF roller. A small smudge on the platen glass can cause a "line" to be produced as every inch of the paper fed via the ADF passes over the area and is picked up by the scanner. The ADF roller is located on the left and underside of your lid. The scanning light sits in this area when using the ADF.

You will want to carefully and fully clean the glass in the ADF scanning area. There can also be a strip of transparent plastic on which there can be a mark or smudge. Look for scratches, tiny spots and marks of any sort. You can use a soft lint free cloth either dry, with a little soap and water or water to clean the glass and may have to scrub until it squeaks to remove certain types of marks.

NOTE: Please do not spray the cleaning solution on the glass.

Another way to ensure the mark is removed is to use a credit card by placing in on a angle and sliding it across the glass in one direction. You can then lift the credit card when reaching the end of the glass and return to the other side to slide it across again.

After cleaning the platen glass, run four to five blank/clean pages through to test it. If the line still appears, please contact us for further steps and assistance.

We hope this helps!

Danny. I just purchased the canon mf 8540 and I have the same problem as MrsPhilli. I've tried cleaning the adf rollers, but it doesn't seem to solve the problem. Thanks!

I have the same problem with a new ImageClass MF229dw...and it's happening when I'm not using the document feeder, but rather when the paper is simply being drawn up from the paper tray. How can I remedy this...it's really irritating.

Hi,

I don't work for Cannon, but I was having same issues with my MF4770n printer, and I believe I have seen this issue at my workplace as well where they have a Cannon production copier that was scanning a line even after cleaning the scanning area and the left side of the plastic.

Make sure that you install a patch from the list of drivers that fixes this issue. If you still have the issue, make sure that you have the latest firmware.

I hope this helps!

I had the same problem and followed the above instructions with no help, but what I miss understood was not to clean anything with the cover where the paper's fed through, but on the actual glass that's under the top.

Here's what I did and it worked.

At the very front of the glass bed there should be a separate thin strip of glass that has a plastic strip over it for protection. That's the strip of glass that scans the paper fed into the scanner from the top. So what you need to do is lift the corner of the plastic, to get under it, and run a cloth or something under the plastic strip and over the glass. You can use almost anything under it to clear the glass/plastic strip. I used a moist cleaning wipe. Not a good idea because of the moisture. I could see the moisture from the wipe clinging the plastic strip to the glass after I wiped it, so I had to go under it again with on of those computer screen cleaners and everything was dry.

I scanned a blank page and the page scanned blank. Perfect!

I hope this helps.

I followed your instructions. Still getting line. There is a tiny little black spec on the top white portion that sits on the glass when closed. Could that be it. I tried glass cleaner. It would not come out.

I can't see your scanner, but scanners have to be perfectly clean or else you will see some line if there's anything resting on the glass where the scanner moves.

Sometimes cleaner will not get everything. I had to use a plastice credit card and lightly scape the surface to get it completely clean

If the line is occuring when printing to the device, it is most likely the Drum or Imaging unit. You will need to buy a new one to remedy the line.

I have an Canon Imagerunner 3035. It suddenly has been showing thick vertical lines. It also notce that it has a greater tendency to do paper jams and seem to be running hot.

I disconneted the machine however, I am concerned that reconnecting is not going to be enough. What do you recommend?

mr 19th !

Thank you so much! Due to your precise description, I was able to clean the smudge off the little glass on my MX 922 and eliminate my problem!

I have this same problem but only on the feeder loads, manual placement yields exact copies. Why?
