Question about Canon DR-1210C Scanner

1 Answer

Scanner inserts vertical line on some documents

After scanning several pages, a vertical line (sometimes two) appears on the scanned documents. This line also prints. Lifting the feeder (as though to use the flatbed) will clear the problem for a few pages then the vertical line(s) reappear. Does this have something to do with static? This is not a cleaning issue as the documents are going through the feeder.

Re: scanner inserts vertical line on some documents

Clean the glass with IsoPropyl Alcohol. Dont use any other solvent. A speck of dust stuck to the glass can give a continuous line in the output

My scanner is now adding a page with a black line that runs from top to bottom of the page and the actual document scanned is page 2. But the document is fine with no line through it. Does this mean that...

Check your scanner software settings. It is probably set at duplex ever time you start to scan. That is why you get two pages for every pass, the front and the back. You must place the document in the feeder in a way that the front side of the document is page 2. You may want to flip it next time you scan. So the main question is why there is black line from top to bottom? That is because there is a piece of dirt stuck on the glass of the scanner. You see, this scanner actually does two scanning when a page runs through it: the front and the back in duplex mode. So there are two scanners in side the box. The front page scanner apparently is dirty and needs to be cleaned with clean cloth and lens cleaner.

When I scan 4x6 photos there is a line (sometimes green) across the entire photo that used to not be there. Scanning larger 8x11 photos the line does not show or when scanning documents. Help! I'm in...

If line is vertical.

Try scanning a bigger document. Use a blank page big as the scan capacity and scan the blank page.

If for example you are using an a3 scanner, scan a blank A3 page.

When scanning blank page set resolution to an high value, so that you does not lose pixels.

Check scan result, and explore the whole document using zoom to see if the line is still present on the test scan of the blank page.

If there is still the line, then it is either a scanner dirty, probably inside glass, or a dafective sensor on CCD sensor array.

If there is no line, then the problem is usually depending on the software.

In that case uninstall the software and install it again.

If that is not enough to fix the problem, try uninstalling software, doing a system restore to a date before the problem started , and then installing software again.

If the line is horizontal , that is usually a loss of power on the high voltage to lamp.
Try reinstalling software first, if that does not fix the problem , and line is horizontal, then it is fault mentioned above.
Horizontal lines at the end of a document may also be caused by faulty scanner control board, or scanner going out of memory.

Very crisp vertical grey line appears (glass clean)

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.

Vertical line in scanned image

This is because of dust sticking to the glass. Clean with isopropyl alcohol (rubbing alcohol) and dont use solvents. For emergency you can use your after shave but take care only to clean the glass portion!
