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.
1 Image Area
This SP sets the bias voltage applied to the image area in the development unit
(adjusted at the factory).
[100 to 1000 / 600 /1 V step]
4 Copy Jobs
This SP is used to switch between Low Duty Mode and High Duty Mode.
Note: The Low Duty Mode is set as the default because wide format copiers
are generally used for low volume copying and printing.
[0 to 1/0/1]
0: Low Duty Mode Copy Jobs (< 400 meters/day)
1: High Duty Mode Copy Jobs (> 400 meters/day)
