"Simplex scan mode".
Eject roller

Gamma
A unit which indicates the changes in the brightness of an image. t is expressed
as a function of the electric input power to devices (e.g. scanner, display) and the
brightness of the image. If the gamma rate is larger than 1, the brightness of an
image increases and vice versa. Normally, the gamma rate is set to 1 when
reproducing the same brightness as the original.
