SP2xxx: Drum

2001* Charge Roller Bias
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
1
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]
Adjust ID Sensor Pattern
Adjusts the voltage applied to the charge roller when making the Vsdp ID sensor
2
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]
Temporary Input
Inputs the charge roller voltage temporarily for test purposes.
3
Do not change the value.
[0 to –2500 / 0 / 10 V/step]
2005* Charge Bias Correction
Vsdp Min
Adjusts the lower threshold value for the charge roller correction.
1
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]
