600 dpi laser printer. For 1440 dpi ink jet printers, such as the EPSON Stylus

COLOR or Photo series, use a scanning resolution of approximately 300 dpi. Try a

scanning resolution of 240 dpi for 720 dpi printing.

Keep the following in mind when you choose a resolution:

■

The higher a resolution you select, the larger the resulting image file will be. For

example, an 8.5

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. To keep your file

size manageable, select the lowest possible resolution that gives acceptable quality.

■

If you need to scan at a higher resolution, you can reduce the size of the image file

by scanning only part of the image. For information about selecting part of an

image, see “Using Marquees” on page 26.

■

If you will be enlarging a file in your image editing software, scan at a higher

resolution to maintain the image quality.

The EPSON Perfection 610’s maximum hardware resolution of 600

× 2400 dpi is

achieved through EPSON’s advanced Micro Step Drive technology. This technology

enables the EPSON Perfection 610 to achieve a maximum sub-scan or vertical

resolution of 1200 dpi or 2400 dpi using “half-stepping” and “quarter-stepping” of

the scanning carriage to double and quadruple the optical resolution. To prevent

enormous file sizes when scanning at the maximum hardware resolution, EPSON

recommends a maximum scan window of 4

× 11.7 inches. Full 8.5 × 11.7 inch

scanning is available at a sub-scan resolution of 1200 dpi or 9600 dpi interpolated.
