Improving Scan Quality - Lexmark 231 User Manual

Scanning to a computer or flash drive
Darkness
This option adjusts how light or dark your scanned documents will turn out in relation to the original document.
Resolution
This option adjusts the output quality of your file. Increasing the image resolution increases the file size and the time
needed to scan your original document. Image resolution can be decreased to reduce the file size.
Original Size
This option sets the size of the documents you are going to scan. When Original Size is set to Mixed Sizes, you can scan
an original document that contains mixed paper sizes (letter‑ and legal‑size pages).
Orientation
This option tells the printer whether the original document is in portrait or landscape orientation and then changes the
Sides and Binding settings to match the original document orientation.
Duplex
This option informs the printer if your original document is printed on a single side or duplex (printed on both sides).
This lets the scanner know what needs to be scanned for inclusion in the document.
Note: Duplex scanning is not available on selected printer models.
Advanced Imaging
This option lets you adjust Background Removal, Contrast, Shadow Detail, and Sharpness before you scan the document.
It also lets you Scan edge to edge.

the white portion.

Question
When should I use Text
mode?
Tip
• Use Text mode when text preservation is the main goal of the scan, and preserving images
copied from the original document is not a concern.
• Text mode is recommended for receipts, carbon copy forms, and documents that only
contain text or fine line art.
