Re: Faulty scanned images
Pls check your color Scan settings. Generally there will be some color difference between the original and scanned Image because, the original is 'reflected light' whereas, the scanned image is a 'source light' on the monitor. The monitor setting can also affect the color output.

All areas outside of the document will be black only. I don't know how you were getting white background.
If you want white background around your scanned image, a) stick the check (in this example) onto a white paper and scan the whole sheet. Ensure double detection is off. b) You can also do this in software, by cropping a larger area outside the scanned image.
There are many options to view the scanned image like Actual size or Fit or Fit vertically or Fit width. The same image will appear different in each case.
Document size can be set before you scan. Your scanner software should give you options for type of document and resolution settings. If your documents are to large, set resolution lower. Example, Black and white or greyscale scans are much smaller in size than color documents. Saving files as jpg will compress the file for storage. If you have an image editing program you can decrease the size of the file after the scan.
That means, your scanner lens are not reflecting images properly so you need to clean ADF kits and Glasses of Lens. i highly recommend not to mess up with your scanner if you are not aware of those all parts and if you are just open up scanner glass cover and clean those all ADF kits otherwise better getting help of a printer Tech. Good luck and rate all answers.
Have long experince with PixEdit program using Kodaks. PixEdit usually comes around it after a firmware upgrade on the scanner. Not sure about this specific model but at least OK on other models of Kodak.
I have the same problem with my 4990. This began when I moved to a new computer running Vista. I've updated all drivers to the latest version including Epson Scan for Vista but the only thing the 4990 "sees" is reflective documents. Negatives are not recognized at all. I know this is probably a different problem from what you are having but the effect is the same.
Grey as you know is different shades of black. Uncompressed TIF can store this information. Compressed TIFF is not designed for this. Compressed TIFF is for blck & white only. Try JPG option. JPG can compress Color & Grey. For pure black & white chose TIFF compression.
