Scanners

Resolution

• An important consideration – 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.

• Low End – 600 by 1200 dpi

• Recommended – 1200 by 2400 to 2400 by 4800 dpi

• High End – 2400 by 2400 to 2400 by 4800 dpi

Scan Area

• Somewhat important – 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.

• Low End – 8.5 by 11.7 inches• Recommended – 8.5 by 11.7 to 8.5 by 14

inches• High End – 8.5 by 11.7 to 8.5 by 14 inches
