Explanation:

This command downloads a user-defined gamma correction table to the scanner. This command is used when suitable gamma correction is not provided by any of the five gamma correction tables built into the scanner.

Specify ‘‘m’’ or ‘‘M’’ for the i parameter when defining a gamma correction table for monochrome scanning, or when setting the same gamma correction tables for all color component colors (red, green, and blue). When defining different gamma correction tables for each component color for color scanning, specify a value for i (‘‘r’’ or ‘‘R’’; ‘‘g’’ or ‘‘G’’; ‘‘b’’ or ‘‘B’’) that is appropriate for the applicable color.

Note:

The brightness command is ineffective when a gamma table defined with this command is selected by the ESC Z (Set gamma correction) command.
