SP2 Mode Number Function and [Setting]
2001* Charge Roller Bias Adjustment
1* Copying Adjusts the voltage applied to the grid plate for
copying.
[–1000 ~ –2000 / –1480V / 10V step]
2* ID Sensor Pattern 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 SP2-
001-1.
[0 ~ 700 / 200V / 10V step]
2005* Charge Roller Bias Correction Adjustment
1* Charge Roller Voltage
Correction 1
Adjusts the lower threshold value for the charge
roller correction.
When the value of VSP/VSG is greater than this
value, the charge roller voltage increases by 30 V
(e.g., from –500 to –530).
[0.1 ~ 1.0 / 0.85 / 0.05 step]
2*
Charge Roller Voltage
Correction 2
Adjusts the upper threshold value for the charge
roller correction.
When the value of VSP/VSG is greater than this
value, the charge roller voltage decreases by 30 V
(absolute value).
[0.1 ~ 1.0 / 0.90 / 0.05 step]
3* Charge Roller Voltage
Adjustment 1
Adjusts the lower limit value for charge roller
voltage correction.
[–1000 ~ –2000 / 1480V / 10V step]
4* Charge Roller Voltage
Adjustment 2
Adjusts the upper limit value for charge roller
voltage correction.
[–1000 ~ –2000 / 2000V / 10V step]
5* Charge Roller Voltage Step Adjusts the correction voltage adjustment step size.
[0 ~ 100V / 30V / 10V step]
2101* Printing Erase Margin Adjusts the leading edge (top), trailing edge
(bottom), left, and right margins.
1* Leading Edge (Top)
2* Trailing Edge (Bottom)
[0.9 ~ 9.0 / 3 / 0.1 mm step]
Specification: ±2 mm
3* Left Edge
4* Right Edge
[0.9 ~ 9.0 / 2 / 0.1 mm step]
Specification: ±1.5 mm
5* Trailing Edge - Back side
Adjusts the trailing edge erase margin on the
reverse side of duplex copies.
[0.0 ~ 4.0 / 1.2 / 0.1 mm step]
Recommended: 2
±
1.5 mm
6* Back Side - Right Adjusts the right side erase margin in the reverse
side of duplex copies.
[0.0 ~ 9.0 / 0.3 / 0.1 mm step]
Recommend: 2
±
1.5 mm
7* Back Side - Left Adjusts the left side erase margin in the reverse
side of duplex copies.
[0.0 ~ 9.0 / 0.3 / 0.1 mm step]
Recommended: 2 +2.5/-1.5 mm
