How do I decide which scanning resolution to select when scanning?
The best scanning resolution depends on the purpose of the scan. Keep in mind that higher resolution settings increase the file size and scanning time, so do not select a higher resolution than you need. See the following table for the appropriate resolution setting to use.
|What you will do with the scanned image||Suggested scan resolution|
|Send via e-mail, upload to web, or view only on the screen||100 to 150 dpi|
|200 to 400 dpi|
|Print or convert documents to editable text (OCR)||200 to 400 dpi|
|Enlarge after scanning at 100%||Increase the resolution setting by same amount you will increase image size after scanning.|
For example, if the resolution is 300 dpi, but you want to increase the image size by 200%, change the resolution setting to 600 dpi.
