When I print multiple copies from my printer through my feeder a continuous vertical line appears on every page approx 1 inch in from the edge of the page.
However, when I print from files no lines appear and quality is perfect. Also, when I copy a page from the glass flatbed individually copy qulality is perfect.
I have cleaned drums as per manufacturer's instructions to no avail.
If the problem only occurs when using the document feeder, the problem is not usually caused by the drum. When using the document feeder, try to notice where the scanner (the light assembly under your scan glass)stops just before the paper is being fed. Some multifunction machines have a small piece of glass that is separate from the large scan glass and the scanner assembly stays parked underneith it as the original is being fed over it. Most likely there is something on the glass where the scanner parks as originals are being fed thru the feeder. When putting your original on the large scan glass to copy, the mark on the glass will only show as a spot, but will show as a vertical line thru the whole copy when using the feeder.
I have MFC 7820N. Noticed same problem as other when making copies. Vertical line used to appear.
Open the Scanner where you can see the glass - Flatbed ( where you put the documents to copy)
Make sure that Glass is Clean.
Now make there is Glass on left side about 1x9 inch. Make sure this glass is clean. I had rubbery stain on that I had to rub it off.
Vertical line does not appear when I make copy from Feeder or Flatbed.
What techbill suggested actually worked on my Canon PIXMA MP530. To the left of the main glass is a strip of glass with a plastic film. I cleaned everything and I was still getting the vertical streak when it went through the feed. I got a flashlight, and found, on that plastic flap, a pinhead of dirt. I got it off, and wala! the vertical stripe is gone.
I own a Brother MFC 7820N. It is fairly new. I have printed or copied a total of 276 pages to date. I was copying a page earlier and noticed a vertical line on the right side of the copy. The line is about 1/2 inch wide. I cleaned the corona wire as per manufacturer's instruction but the line is still there. What should I do?

When you use the flatbed the copy is perfect because the ccd sensor is under the glass cover and obviously is free form dust/ dirt.
On the other hand if you use the feeder the ccd sensor is located in between the roller assembly (not sure exactly for this model).
This means that the page is scanned by the ccd in the feeder, any dirt on the ccd will appear as a black line. I assume that you are feeding papers from the side and not from the top that is why you get a horizontal line.
A quick test to see if the ccd sensor is dirty is to feed the paper from the top side to the feeder. If you get a vertical line it is a proof that your ccd sensor needs to be cleaned.
The worst case is that the sensor in the feeder assembly has a tiny spot that is damaged and it is causing the black line.
So , first try the test, then open the feeder assembly, locate the ccd and clean it. Hope that this helps.
To determine if the line is caused by the cartridge, try printing a test page. Not sure of your model, but there should be a menu setting to print a configuration page. If that configuration page prints out clean, then there is likely debris in the scanning area of the document feeder. You should be able to locate the debris by lining up the vertical line with your feeder. If you could reply back with the model of your Canon device, we can help you a bit more. Alternatively, you should be able to pull the cleaning instructions from the manual for your copier.
When copying from the feeder the page is fed across a fixed point at the head of the flatbed. Any dirt etc on the glass at this point can present as a dark line running vertically down the printed page. When copying from the flatbed, the scan head is moved down the page so any dirt on the glass will only appear as specs. Try cleaning the glass, especially at the head of the flatbed where the feeder is loading the page to be copied.
Check your flat bed and Document feeder scanning glass need to be clean, if any dot or dust in scanning glass of document feeder it will appear a line, check this points first 1- Check printouts from computer or FAX if it is clean problem in scanning section 2- Check using Copying a blank paper using only Flatbed if it prints without any line its problem from document feeder Scanning glass So solution is clean the Document feeder scanning glass using wet cloth, note careful about wet cloth switch off the machine and clean it
are you printing from Doc feeder or glas?? if from feeder then try to make a copy from the glass, does it still do it? yes problem is with drum. No? problem is with the small scanning glass to the left, look carefully see if any spots or lines on the 1inch glas --- clean it
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.
the problem is in the scanner, open it up and see if you can find any smudges, and clean any obstruction, any ink, liquid eraser residuals, can cause this part to appear as lines on your copied faxed image.
dont concentrate on the printer this is a scanner problem
Does this happen both when copying and printing? For printing solution, try another toner cartridge. If lines continue to appear when copying (primarily through the automatic feeder) then lift the auto feeder, and clean the glass -mainly the narrow piece on the left side.
