Using the Scanner Functions
Scanning Area
Use this function to scan a specific portion of the original image.
You can choose a rectangular area anywhere within the maximum
scanning area of the scanner as determined by the current resolution
and zoom settings.
Data Format
The data format determines how many bits are used to represent a
pixel. A pixel (picture element) is the tiniest area a scanner “reads.”
The number of bits/pixel (from 1 to 8 bits/pixel/color) determines
how many colors or how many shades of gray the scanned image
data can represent. The larger the number of bits per pixel, the
greater the number of shades of gray can be represented. In
monochrome (black and white) scanning, for example, a data format
of 8 bits/pixel can represent up to 256 shades of gray.
Color Mode
The color mode specifies either color scanning or monochrome
(black and white) scanning. In color scanning, you can choose either
page sequence mode or line sequence mode. In monochrome
scanning you can specify a dropout color, as discussed below.
Color page sequence mode
Use this mode when you don’t require the color correction function.
The carriage scans the document table three times, once for each
color: green, then red, then blue.
Color line sequence mode
Use this mode when you require the color correction function to
achieve more accurate color. The carriage makes only one pass,
reading each of the three colors for each line.
