Increase the Epson Scan 2 Resolution setting in your scan. 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 a smaller size.
Select the Epson Scan 2 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
