Data Form Commands
Data form commands regulate the amount of image data sent to the
computer (as determined by the setting for scanning color, resolution,
tone, and zoom).
1. Set Color Mode (ESC C)
This command sets either color or monochrome scanning.
If you select color scanning, you must specify page scanning, line
scanning, or byte scanning. Page scanning scans the entire page three
times; once for each color. Line scanning scans for each color on a
line-by-line basis. Byte scanning scans on a byte-by-byte basis.
If you select monochrome scanning, you can specify red, green, or
blue to be a dropout color.
ESC C and other commands
Selecting line scanning or byte scanning enables the use of the Color
Correction Command (ESC M).
2. Set Data Format (ESC D)
This command sets the number of bits available for representing each
color (green, red, and blue during color scanning). The number of bits
determines the number of shades that can be represented for each
color; the more bits, the more colors available. However, increasing
the number of shades available also increases the overall data required
to represent an image.
