Preview Window
Displays an image after preview-scanning. The scanning area (black frame) is specified on the displayed
image.
Dragging the mouse in the preview window allows specifying the scanning area (black frame), changing
the frame size, and moving the frame.
The black-frame area is displayed in values <Output Size>.
Image Type
Select the type of image to be scanned.
The following four types of image scanning are selectable:
• Monochrome image (no halftone correction)
A method suitable for an image containing mainly text and drawings. Select this type when halftone
correction results in a blurred image.
• Halftone image (error diffusion)
This method, using no uniform pattern in halftone, is suitable for natural images such as photographs
and produces smooth images. The method, although requiring somewhat large file sizes, produces
high-quality images in comparison to the dither method.
• Halftone image (8x8 dot dither)
This method, which produces images with a unique uniform pattern, is suitable for photographs. This
method, with somewhat lower image quality, reduces file sizes.
• Grayscale image (256 scales)
This method, best suitable to natural images such as photographs, produces tones with high fidelity by
no halftone correction. Compared to halftone image scanning, this method requires longer scanning
times and results in larger file sizes.
Resolution
Select the resolution for scanning.
<Standard>, <Fine>, and <Super Fine> are resolution levels for FAX communication.
Paper Size
Select the size of originals to be scanned. The size and orientation of the preview window changes
according to the selected document size.
Lock
Fixes the size of the scanning area (black border) in the preview window, disallowing changing the size.
Slice Level (valid only when monochrome is selected)
Specify the value of distinction between monochrome for monochrome manuscript. Adjust the value
according to density of a manuscript to be scanned.
