Menu Copier Menu/Copy Mode/Custom Config/GrayScale Adjust
Purpose Allows you to specify whether gamma correction is used.
Choices None and Photographic
Notes None—If this is selected, then data from scanner is directly
printed. This provides better quality for copying photocopies.
Photographic—This option provides a gamma table
adjustment for the image. This should be used if you are
copying photographs.
Menu Copier Menu/Copy Mode/Custom Config/Binary Adjust/
Threshold
Purpose Allows you to adjust the brightness for Binary B/W mode.
Choices There are 15 levels of threshold available. Each level changes
the threshold slightly.
Notes Use the Previous key to move the message-window cursor
from the center (the default position) towards the left to a
Darker (less bright) setting, or use the Next key to move the
cursor towards the right to a Lighter (brighter) setting.
Increasing the threshold makes light and dark areas in the
halftone appear lighter, while decreasing the threshold makes
light and dark areas appear darker.
Each increment of change is significant in output quality.
Therefore, we recommend that you change the setting by only
one level, print out a test copy, and then determine if further
modification to the contrast is necessary.
