EPSON SCANNING TIPS AND TROUBLESHOOTING GUIDE

SELECT A SUITABLE RESOLUTION

The best scanning resolution depends on the purpose of the scan.

When you specify a high resolution, the number of pixels increases and the scanned image

becomes finer in texture. However, increasing the resolution causes the file size to increase. For

example, an 8.5 x 11-inch original scanned at 300 dpi can produce a 24MB file. The same original

scanned at 72 dpi creates only a 1.3MB file. Large files take longer to process and print, so select

the lowest possible resolution that produces acceptable quality.

Specify a suitable resolution according to your scanning purpose. Recommended resolutions for

scanning print material:

Web pages

Sending E-mail

Printing

Saving as a PDF file

Sending Fax

OCR (Optical Character Recognition)

Use Target Size to specify the output size of the scanned image.

If you are enlarging your image, you must increase the resolution (dpi) proportionally to maintain

the resolution of your original. Try scanning slides at 1200 dpi or higher.

If you reduce the size of the image on a page, it does not decrease its file size.
