2201 Development Bias Adjustment
Image Area (Normal Speed) 001
Adjusts the development bias for copying.
[-200~-800 / -550 / 10 V]
This can be adjusted as a temporary measure if faint copies appear due to an aging
drum.
ID Sensor Pattern (Auto Process Control OFF) 002
Adjusts the development bias for making the ID sensor pattern for VSP measurement
when the auto process control is set to off.
[-200~-800 / –400 / 10 V]
This should not be used in the field, because it affects ID sensor pattern density, which
affects toner supply.
003 Transparencies
Adjusts the development bias for copying on Transparencies.
[-200~-800 / –240 / 10 V]
004 ID Sensor Development Potential
Adjusts the development potential for making the ID sensor pattern for the Vsp
measurement when the auto process control is set on.
[140~380 / –480 / 10 V]
005 Image Area (Low Speed)
Adjusts the development bias for copying in low speed mode.
[200~800 / –370 / 10 V]
006 ID Sensor Pattern (Auto Process Control OFF/Low Speed)
Adjusts the development bias for making the ID sensor pattern for VSP measurement
when the auto process control is set to off and the machine is in low speed mode.
[0~200 / * / 10 V]
Note: The default setting is different depending on the model and geographical area.
