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 the software. 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.
Increase the resolution setting in your scanning software. Increase the resolution by the same amount
you will increase the image size to retain a high image quality. For example, if the resolution is 300 dpi
(dots per inch) and you will double the image size later, change the resolution setting to 600 dpi.
• You will scan the image at 100% or smaller size.
Select the resolution setting based on how you will use the scanned image:
• Email/view on a computer screen/post on the web: 96 to 200 dpi
• Print/fax/convert to editable text (OCR)/create searchable PDF: 200 to 300 dpi
• You will scan a long original.
Scan paper up to 240 inches (6096 mm) in length with a maximum resolution of 300 dpi or less.
