Re: Black vertical line on scans

[ Edited ]

I have the exact sasme issue with my MX 922 scanner. I just spent 1 hour and 6 minutes on the phone with a very frinedly Cannon Support tech.

 

In my case it only happens when I scan on the big glass, not when I use the ADF. Each time I scan anything that is 8.5 inches wide (full size letter or anything else with the same width) it introduces that black vertical line on far the right side.

The line shows everytime in the scan preview as well as in the final saved scan, no matter what format I use to save, i.e. JPG or PDF.

 

It also happens when I use the MAC OSX Image Capture Utility to scan instead of the Canon IJ Scan Utility..


Copying, and printing works fine. As does scanning with the ADF.

The tech was not able to fix the issue.

Re: Black vertical line on scans

I am having the same issue with my Pixma TS6120.  I am in the process of scanning photos to save to files on my pc. The only difference from the rest of the complaints is that I am not feeding my photos into the printer.  I am placing them directily on the glass to scan.  I tried cleaning the glass, updating the firmware and restarting the printer with no success.  I don't know what else is left to try.  Any suggestions or help would be greatly appreciated.

Re: Black vertical line on scans

I just started getting this black line also on my Canon Maxify MB2320.  I tried everything they said here but to no avail.  I finally out of frustration rubbed my thumb across the small glass area for the ADF reader.  I thought it would smear or something but low and behold, the black line is gone now.  I tried the credit card trick, I tried the rag dry and wet, I tried blowing it out and nothing worked.  I checked for firmware and software updates but there were no new ones.  I rubbed my thumb acrossed it straight twice and it worked.

 

Give it a try.  Make sure your hands are completely clean and completely dry... Do not assume your thumb or fingers are clean.  If you have touched anything with your thumb or fingers then they are not clean anymore... Make sure they are COMPLETELY clean and dry.

Re: Black vertical line on scans

That only works if the black vertical line appears due to using the ADF.

In my case ADF scanning works fine. I get the black line when I scan letter size pages on the glass platen.

 

No solution for fixing that yet.

Re: Black vertical line on scans

Bingo! Abosolutly right. Glass LOOKED clean but it wasn't. As I slowly passed my finger on the glass I could feel  something. I took a credit card edge and removed what ever it was. Wiped with a clean soft cloth and problem solved. No more lines. To be clear, this was on the small strip of glass in front of the big glass bed. Thank you.

Re: Black vertical line on scans

I've hit the black vertical line problem today with a Pixma TS8052 - simple printer/scanner with no ADF.  It worked fine yesterday but all photo scans today have black lines, scanning at 600 dpi whether jpeg or Tiff.  The platen is spotless and was recleaned.  Scans were initiated either on the control pad at the front of the printer or with 'My Image Garden' software.  The very odd thing is that scanning with Microsoft's simple scan app at the same resolution, etc. produced no lines.  This suggests the underlying problem is a software one.  Anyone like to comment?  Ideally I'd like to get back to using the printer's control pad.

Re: Black vertical line on scans

I'VE SOLVED THE PROBLEM OF THE BLACK LINES APPEARING ON THE PIXMA TS8052 SCANNER!  I had a nearby desk light shining on the platen to check that it was dust and speck free between scans of photoprints.  I assumed that closing the lid would shield the light and of course mostly it did but apparently some light leaked in for when the light was turned off leaving only the ceiling room lights, the black lines disappeared.  Why light leakage causes black lines I don't know.  Maybe some others who have difficulty getting rid of black lines have hit the same problem.  Canon need to look into a slight re-design of their lid.

Re: Black vertical line on scans

Pixma MX922. YEA, THANKS for the credit card trick on the small glass section. It worked!! I too had a solid line using the autodocument feeder, but not when making a single copy on the large glass sheet. Had tried cleaning with a computer cloth, an eye glass cloth, a paper towel and each time, the black line was still there. As a last resort, I slid a credit card over the glass. I have no idea what the credit card removed, but the line was finally gone. YEA again! Whatever was on the small glass section, my eye was unable to see.
