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
