[Operation]
The operation is similar to simulation 43-01.
[Function]
Used to adjust the exposure correction amount in the SPF/RSPF mode. The adjustment is
made by adjusting Vref voltage variation for the OC mode.
When this simulation is executed, the current set value is displayed in 2 digits (Default: 50).
Change the set value and press [START] key to save the setting and make a copy.
When the set value is increased, copy becomes darker. When the set value is decreased, copy
becomes lighter. (Adjustment range: 1 – 99)
