Re: Canon 9900f scanner glass removal
I would not worry about the underside of the glass unless you are having problems. The focal length of the ccd that captures the image is very specific and probably will not pick up anything under the glass. It is normal for the underside to look foggy but it will not hurt anything.

How on earth did the underside of the glass get dirty?
Ok, never mind that... in the end, it's NOT worth it. In the old days, you could have since scanners were as big as printers are today... but now they are definitely NOT designed for the consumer to service. The scanner is designed for accuracy, even if you were to get it all apart, the odds that you maintain the precision and integrity of the bulb, the track on which the bulb moves, etc, are very slim.
Suggestion... How is the printer you have holding up? If it's getting on in age, it may be a wise investment to purchase a dual scanner/printer (as long as you are spending the money).
Possible causes, CCD failure, smudges or marks that can only be picked up by the CCD if the underside of the scanner glass is dirty. Uninstalling/reinstalling your scanner driver will eliminate if its software related or not. From the looks of it, could be with the CCD if the lines are in the same area with every scan attempted.
