Image Setting Commands
Image setting commands are commands that tell the scanner what kinds of image processing to perform on the image data. Brightness settings and gamma correction (adjusting for input and output brightness) settings are examples.
1. Set brightness (ESC L)
This command sets the scanning brightness. If the standard brightness setting results in images that are too dark or light, use this command to adjust the brightness. You can select from among seven brightness levels; settings in between these seven levels are not possible.
The Set brightness (ESC L) command is ineffective when a gamma table defined with the ESC z command is selected by the ESC Z (Set gamma correction) command.
