Selected FAQ

How do I decide which resolution to select when scanning?
Resolution refers to how many dots or pixels per inch (dpi) or dots or pixels per centimeter (dpcm) your image contains. The best resolution for a scanned image depends on the type of image you're scanning and your final output device. For most images except line art, use a scanning resolution that is approximately one third of your output resolution. For example, use a scanning resolution up to 100 dpi with a 300-dpi laser printer, and up to 200 dpi with a 600-dpi laser printer. For high dpi ink jet printers, such as the EPSON Stylus Color or Photo series, use a scanning resolution of approximately 240-300 dpi. For on-screen viewing, you can scan at 72 dpi. Keep the following in mind when you choose a resolution: Higher resolution settings result in larger file sizes. 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 consider the practical limitations of your computer system when selecting a resolution. To keep your file size manageable, select the lowest possible resolution that gives acceptable quality. When scanning at a higher resolution, reduce the file size by scanning the image and cropping or removing the unneeded empty spaces.
