2001* Charge Roller Bias
1
Setting (Copying)
Adjusts the voltage applied to the charge roller during printing.
This value will be changed automatically when the charge roller bias correction is
performed.
Note that if this value is changed, the charge roller voltage will be corrected based on
the new voltage.
[–2100 to –1500 / –1700 / 10 V/step]
2
Adjust ID Sensor Pattern
Adjusts the voltage applied to the charge roller when making the Vsdp ID sensor
pattern (for charge roller bias correction).
The actual charge roller voltage is this value plus the value of SP2001 1.
[0 to 400 / 200 / 10 V/step]
3
Temporary Input
Inputs the charge roller voltage temporarily for test purposes.
Do not change the value.
[0 to –2500 / 0 / 10 V/step]
2005* Charge Bias Correction
1
Vsdp Min
Adjusts the lower threshold value for the charge roller correction.
When the value of Vsdp/Vsg is less than this value, the charge roller voltage increases
by 50V (e.g. from –500 to –550). The size of the increase depends on SP2005 3.
[0 to 100 / 90 / 1%/step]
