Check the glass of the scanner. It may have some stain over it.

HP ScanJet 4670 - yellow lines or streaks in scans


You have a dirty glass. Take a lint free cloth and water and wipe the glass making sure you leave no streaks behind. Sometimes you have to take a flashlight and examine the glass. Just a little spec, the laser will drag all the way down.

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 appears on the faxed page sent to


This sounds like a dirty scanning glass in the adf feeder. clean the glass with a soft cloth. if this doesn't solve the problem, there might be dirty optics under the scanning glass.

When scanning, the scanned page is not readable from a third of the page down to two thirds of the page.


It is important that the item you scan comes in close contact with the scanner glass. If the resulting scanned image is not clear, check to see that the item is in full contact with the scanner glass. The scanner uses optical character recognition (OCR) to convert text on a page to text that you can edit on your computer.
  • If you scan text but cannot edit it, make sure that you make the following selections during scanning:
  • Scanned text might not appear on your computer exactly as it appeared on the original, especially if the original contains faint or smudged text. For example, some characters might be incorrect or missing. As you edit the text, compare the scanned text against the original, and then make corrections as necessary.
  • To change text scanning options, click the Scan Document Settings button in the initial What are you scanning? screen.
  • The OCR software is installed by default when you install the HP Scanning software during scanner setup. If you use the Custom option when installing the software, you can choose not to install the OCR software. Try reinstalling the software using the default install options.
  • Email to jdiaz@coretec.us
  • If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
    Thanks, Joe

Vertical lines in scanned documents


Scan glass has muck on it, needs to be perfectly clear, it is just in where you feed originals.
