Hello, My problem comes from scanning & copy printing only, not from any printing from PC. A thin line appears in the print copy at the same position of every and any print while scanning and printing. However there is no unwanted mark whtsoever while printing direct from PC. Also, any scanned image when viewed in the monitor the same line additionally appears. The line is in the transverse direction of the scanner light movement. Problem is indicative of the scanner section troubleshooting. Please help me in getting rid of the line mark from scanning.

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.
I have no idea what "paperport 11" is. That being said, normally a line down the page when copying or scanning is caused by dirt on the Automatic Document Feeder glass, Not the flatbed glass. It is a thin strip of glass to the left of the flatbed scanner glass. 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.
Does the same thing occur with a different document.. Because it is not repetative, it leads me to believe the line is being drawn at the direction of the software. Try printing a test page, and see if the line appears. If not the issue is from within the word processsing software. It almost sounds like a legal template for a pleading..
Hello, A dirty glass base can cause ‘spots’ or blemishes to appear on your final printout. Additionally, if you had some sort of opaque liquid that may have transferred on to the glass base from a previous operation.But the majority of the unwanted vertical lines are generally caused by either a dirty or damaged print roller or faulty LEDs in the Scanner Module. To separate one from the other you have to check the following: Do you only see the lines with a Scan operation? Do your print jobs print fine without any unwanted lines? If you only see the unwanted lines during a Scan operation, then most likely you have a fault/dirty/obstructed LED module. If you see the unwanted lines with all print operations (Scan, Print and Copy), then you most likely have a worn out, damaged or dirty Print Roller. Hope this helps… RojoSho
