(Class 1, 2, and 3)
120 [Dev. g Target] Development Gamma Target ([Color])
Adjusts the development gamma by changing the Vref value used for toner density
control.
Vref is automatically corrected so that the gamma measured during the process control
self-check becomes "the value set with this SP mode ± 0.15"

Density Adjustment, the machine supplies or
consumes toner so that the development gamma
is within ± 0.15 of the gamma target.
