Xerox 123 用户手册

The scan resolution affects the quality of the fax the remote machine receives. A higher 
resolution yields better quality. A lower resolution reduces communication time.

Standard
Scans documents with a resolution of 200 × 100 dpi. This option is recommended for 
text documents. It requires less communication time, but does not produce the best 
image quality for graphics and photos.

Fine
Scans documents with a resolution of 200 × 200 dpi. This option is recommended for 
line art and the best choice in most cases.

Superfine (400dpi)
Scans documents with a resolution of 400 × 400 dpi. This option is recommended for 
photos and halftone illustrations, or grayscale images. It requires more communication 
time, but produces higher image quality.

Superfine (600dpi)
Scans documents with a resolution of 600 × 600 dpi. Use this option to produce the best 
image quality at the cost of increased transmission time.

This feature allows you to select the type of documents you are scanning.

Text
Select this option for documents that contain text only.

Text & Photo
With this option, text and photographs are automatically identified and an appropriate 
quality mode is selected for the individual areas.
