Precautions for Scanning at High Resolutions
Please note that file sizes increase almost exponentially as the resolution is raised when scanning in
color mode. Scanning at high resolutions may require more time for scanning and image processing.
You are recommended to avoid raising the resolution beyond the minimum requirement to scan in
color mode.

Resolution Guidelines
• For uploading to a web site or viewing on a computer monitor, choose 75 dpi
• For scanning print photos and magazine clippings, choose 150 - 300 dpi
• For printing on a inkjet printer, choose a resolution approximately half the printer’s rating (180 dpi,
360 dpi, 600 dpi or 720 dpi)
A resolution higher than 600 dpi is effective for scanning relatively small originals that will be blown
up to larger sizes for printing.
• The maximum size of files scanned by the bundled PhotoBase program is limited by
Windows Me and Windows 98 to 256 MB.
