What Scanner is Best for You?

From low end, through mid range, and up to high end, you may feel spoiled for choice, perhaps even confused, amid the wealth of scanner brands and models. As with any other purchase, consider your needs and available budget. The table below tries to look at the home/SOHO and SMB scanner market while analyzing price and four chief parameters - resolution, scan area, imaging technology, and interface.

    • Resolution: The resolution indicates how detailed the digital image will be. The higher the numbers, the sharper the scans will be. This is especially important when making enlargements.
    • Scan area: While few home users will need to scan legal-size documents, business users may find the letter-size scan area of most scanners too small. A larger scan area also makes it easier to scan large books, maps, drawings, paintings, newspapers, and tabloids.

    • Scan technology: CCD (charge-coupled device) scanner heads are far more common than CIS (contact image sensor) models, and generally provide higher-resolution scans. CIS-based scanners are often smaller than CCD scanners and may not need a separate power cord, but some models will scan faster if you use an optional power cord instead of powering them from the PC's USB port. CIS scanners can't use transparencies or automatic document feeders.
    • Scanner ports: Your PC has to have a compatible port to connect with the scanner. Most scanners come with a USB 1.1 port, which is fast enough for small jobs. Some scanners offer dual interfaces--like USB and parallel--to allow them to work with older computers. Only the newest USB 2.0-capable PCs are able to reap the speed benefits of a USB 2.0-capable scanner.
