SP2-xxx: Drum-1
5.6 SP2-XXX: DRUM-1
2001* Charge Bias
Setting (Printing)
001
Adjusts the voltage applied to the charge roller for printing.
Setting (P Pattern)
002 Adjusts the voltage applied to the charge roller when making the VSDP ID
sensor pattern (for charge roller voltage correction). The actual charge roller
voltage is this value plus the value of SP2001-1.
2005* Bias Control
Bias Correction 1
001 Adjusts the lower threshold value for the charge roller correction.
When the value of VSDP/VSG is greater than this value, the charge roller
voltage increases by 30 V (e.g., from –500 to –530).
Bias Correction 2
002 Adjusts the upper threshold value for the charge roller correction.
When the value of VSDP/VSG is greater than this value, the charge roller
voltage decreases by 30 V (absolute value).
Bias Adjustment 1
003
Adjusts the lower limit value for charge roller voltage correction.
Bias Adjustment 2
004
Adjusts the upper limit value for charge roller voltage correction.
Bias Adjustment 3
005
Adjusts the correction voltage adjustment step size.
