In Home Mode, you can change the resolution only if you select Other as the Destination setting.
In Professional Mode, you can select the resolution you want at any time.
Before you select the scan resolution, you should consider whether you will enlarge the images, and if so, whether you will enlarge them before or after you scan. Follow these guidelines:
You will not be enlarging the images.
If you will scan the images at 100% size or smaller and will not enlarge them later, you can accept the Resolution setting selected by EPSON Scan based on your original and destination settings.
You will enlarge the images as you scan them (increase the Target Size setting).
If you will enlarge the images in EPSON Scan so you can use them at a larger size, you can accept the Resolution setting selected by EPSON Scan based on your original and destination settings.
You will scan the images at their original size, but then enlarge them later in an image-editing program.
If you plan to enlarge your images later in an image-editing program, you need to increase the Resolution setting to retain a high image quality after enlargement. Increase the resolution by the same amount you will increase the image size. For example, if the resolution is 300 dpi (dots per inch), but you will increase the image size by 200% in an image-editing program, change the Resolution setting to 600 dpi in EPSON Scan.
Click the arrow next to the Resolution list and select the number of dots per inch at which you want to scan. See the table below for some guidelines:
What you will do with the scanned image
Suggested scan resolution
Send via e-mail, upload to web, view only on the screen
96 to 150 dpi
Print, convert to editable text (OCR)
Enlarge after scanning at 100%
Increase Resolution setting by same amount you will increase image size after scanning
After selecting the Resolution, you can preview your image and make any necessary adjustments. See your User's Guide for further information.
There will be some loss of image quality if you enlarge images from their original size. You may notice some loss of quality, depending on the size or quality of the original image. For example, if you scan a passport size photo and enlarge it to A4, the image will not be as sharp.
