If you live near Essex I have one I was going to give away, I've never used it and its been sat under my desk for 18 months. I have the scanner & plug but not got the driver disc anymore.

Bit Depth
For every pixel in an image a scanner can remember a certain number of bits. This is also known as bit depth. The higher the bit depth the more likely you are to get a good crisp image since the scanner will have more information from which to distinguish between shades of the same colour. Look for a bit depth of at least 24 as this will be adequate for most documents and web graphics.

If you plan to get a scanner for slides, negatives or transparencies you should look for a bit depth of at least 30. Don't be concerned if your monitor or printer can only handle 24 bit colour because despite this limitation the higher bit depth will still be reflected in your printout or reproduction.


Optical Resolution
The optical resolution is a measure of dots or pixels per inch (dpi or ppi). As one might expect the higher the number of pixels per inch the better the resolution and image quality. An optical resolution of 300 dpi is probably adequate for the average user while a graphic artist might opt for a 600 dpi.

If you want to scan slides, negatives or transparencies you will need a 1200 dpi resolution.

Speed
Speed depends on scanning resolution. If you buy a scanner with 1200 dpi resolution you will wait longer for the image than one that has only 300 dpi. An efficient time for a 600 dpi colour scan is around 100 seconds or 30 seconds for a monochrome 300dpi scan.
Software
When you purchase a scanner you are also paying for the software that comes with it. Normally you will get a pretty basic version of image editing software. Upgrade to a full version if you want to work with images a lot or create interesting effects.

If you want to edit the text within your scanned document you will need Optical Recognition Software (OCR). While a scanned image can be read on a monitor, the computer sees it as a picture, not as editable text. OCR examines the scanned image and converts it into a format that can be read by a word processor, spreadsheet or database. Many scanners will come with limited OCR software, so upgrade your software if scanning and editing text is your primary concern. Note, if editing scanned text is all you want to do then save money by buying a black and white scanner.
