The underneath of the glass on my MP830 is dirty; like smoky color. I can't help but think this would effect some scans. Has anybody ever figured out how to remove glass so all of it can be cleaned? Is this something in a manual that I'm missing? Any pointers to a website that would have this info?
Best left alone this one, even printer technicians dont remove glass on the scanner unit they just replace the whole scanner assembly, the reason? there are a lot of plastic clips holding it together and springs and cables that are easily dislodged,
often the improvement in scan quality isn't as great as one would think. the scanner assembly can be replaced as a unit for around $200

As it sounds its a dirty scanning glass. Open the top of the scanner so that you can see the scanning glass.. If your standing in front of it you will see on the left hand side a strip of thinner glass.. Take a damp cloth (better cloth with spirits/surgical alcohol) and clean the both the small and the large scanning glass. These lines normally cause if the glass is dirty. Especially if your using the document Feeder. As a lot of time wet ink or typex or correction fluid gets stuck on glass which will cause these lines.
Hope it helps
The cause of this problem is usually a dirty scanning glass (there might be ink or white out on the glass). Check the glass really closely or the cause could be dirty optics or a bad CCD board. There are mirrors underneath the scanning glass. Dirty optics can cause lines when faxing or copying. If you can not access these mirrors, they would have to cleaned by a technician.

If the scanner glass or the white scan background (the white portion of the lid) are dirty, the scan might be different than intended. A dirty scanner glass (fingerprints or smudges) slows down performance by as much as half a minute and affects scan quality. Performance slows because the product is actually processing the smudges on the glass. Turn off the product , and then clean the glass with a soft cloth or sponge slightly moistened with a nonabrasive glass cleaner. If there are visible contaminants under the scanner glass, the product must be sent in for servicing. You cannot remove the scanner glass to clean inside.
Reinitialize the scanner by turning off the product and unplugging the power cord. Make sure that all original documents are removed from the product and that the scanner glass on the product is clean. When the power is reconnected and the product is turned on, the scanner recalibrates.
The computer video driver and video settings might change the image appearance slightly. The product scans in 24-bit color. Setting the video display settings to less than 24-bit, or 24 million colors, results in a loss of color information on the computer monitor. The video driver might change the appearance of colors when viewed on the monitor.
Open ADF (automatic document feeder) cover and clean scan glass underneath. White out or post-it notes are notorious for leaving behind residue on glass when scanned. Any dot, spot or dirt will show up as a black line due to shadow effect.
If this is happening only when you are scanning using the automatic document feeder, check for something blocking light above the scanner. If you open the scanner top, look along the left side of the scanner glass where the paper is scanned by the automatic document feeder. If you see anything on the glass there, clean it with a soft cloth dampened with clean water.
Sounds like a dirty seal glass.
The small srtip of glass on the left side of the scanner. Clean it well.
If there is no streak when scanning on the flad bed portion, then there is most likely a small almost non visible contaminant on the seal glass.
Use a regular piece of 20 pound paper crumpled with some glass cleaner or alcohol and clean that glass thorughly
