If the line is disappearing with a lower contrast, then it is definitely scaratch/glue/dust on the glass. Clean with Isopropyl alcohol. Dont use solvents.

I have a big black line down the middle of my scans


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.

This must be a vertical line and appearing at the same location on all drawings! Please clean the glass thoroughly. It must be dust particle sitting on the glass.

Getting vertical lines on scanned pages when duplex scanning on canon dr-3080c II scanner Only on duplex side of pages, though. Front page still shows up clean.


It is dust on the glass, clean it thoroughly. You will find it at the same location for all drawings and may get faded for lower brightness!

HELP BIG JOB DUE TOMORROW! I have a DR 9080c and it just started putting two lines on the scanned pages. I have cleaned the rollers, the glass, run cleaning pages through even used compressed air to blow...


Vertical lines are from dust on the Glass. Use Isopropyl alcohol, no solvents pls. Try scanning in diff contrast levels and if the thichness varies, it is confirmed dust on glass, whereas any fault in the reading unit will be constant and also have sharp edges.

Wipe the rollers with a damp cloth thoroughly. Remove all the dust in the glass for a claen scan. The red color roller roller in the bottom needs thorough cleaning, rotate with hand gently (in power-off mode) and clean it thorughly. No solvents pls, except Isopropyl alcohol for cleaning

Everytime I scan, there are 2 vertical lines on appearing on the pdf file. I can't clean the stell roller as it's locked. can only clean the showing part.


Hello,
You need to get to the scanner's Glass area and what you will sometimes find is some ink or white-out there all it takes is a small drop or smear to screw things up. Clean the glass with isopropyl alcohol, then some glass cleaner and the lines will go away.

Good Luck!

How 'crisp' is the line? IF it is same thickness even at different contrast levels, then it is likely the scan module is affected. If the thickness varies, or has jagged ends, then it is dust on the glass or a scratch of may be a dust particle sitting on the scan module. This has to be cleaned.

Line going down page


Don't know if this is a solution per se but I replaced the glass bar (there is a part # on it) on the inside front of the scanner and still got a line. Then I played around with the back scanner glass and still got a line then I got in there real good and cleaned and when I scanned something it would show no lines until I saved the document then I got two lines. Thought it was my software going haywire but I did not give up, got some canned air and alcohol and cleaned the glass once again and blew out every part I could find and the problem resolved itself. Apparently the smallest piece of lint or dust, smudge or anything foreign on the scanner lenses will cause this line. But I love this scanner and I wasn't willing to give it up or pay $600 for a new one. Only had it a little more than a year. Persistence seems to be the key but check those little scanner bars and be careful, they are tricky to get out.

Streaks in image scanned by Canon DR-2580C Path-Through


The staples cannot reach the sensors. They could have scratched the glass above the sensors. Clean the glass with IsoPropyl alcohol. Try scanning a few images to find if the scratch marks are on the same place on all images. Once confirmed that the glass is scratched, you can change the glass. You need a technical expertise to change or call service staff.
