2201 Development Bias Adjustment
This SP sets the development bias to adjust the amount of toner used in the
image area.
The amount charge applied by the CGB power pack for image transfer
varies depending on whether CV is high or low.
Toner density is controlled to raise toner density in Low Duty mode when
copy volume is high.
For this reason, SP2201-4 can be used to switch between High Duty Mode
(> 400 m/day) and Low Duty Mode (< 400 m/day).
The default setting is Low Duty Mode.

when the Low Duty Mode is selected with SP2201-4 (factory adjusted).
