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.

    SCANNING PROBLEMS The edges of a document are not scanned Place documents away from the edges of the document table to avoid unwanted image cropping. The area with a width of maximum .08 inch (2.1 mm) from the horizontal guide and .06 inch (1.5 mm) from the vertical guide cannot be scanned.
