Displays the Vsg value of the center ID sensor.
Vsg is normally 4.0 ± 0.5 V.
If Vsg is out of the adjustment range and this is detected 3 times consecutively, it
leads to SC385.

Vsg R *BCU [0.00 to 5.00 / - / 0.01V/step] 3107 005
Displays the Vsg value of the rear ID sensor.
Vsg is normally 4.0 ± 0.5 V.

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”
