Scan Resolution Guidelines
The Resolution setting, measured in dpi (dots per inch), controls the amount of detail captured in your
scans. Increasing the resolution raises the amount of detail captured but comes with the following
disadvantages:
• Larger file sizes
• It takes longer to scan your originals, send/receive your scans by email or fax, and to print your scans
• The image may become too large to fit on your display or print on paper
If you plan to enlarge a scanned image so you can print it at a larger size, you may need to increase the
resolution from the default resolution set by Epson Scan 2. Follow these guidelines to determine the
resolution setting you need:
• You will scan the image at its original size but enlarge it later in an image-editing program.
