Charge Roller Bias Adjustment
Printing [–2100 ~ –1500 /
–1650
/ 1 V/step] 2001 1
Adjusts the voltage applied to the charge roller for printing. The voltage changes
automatically as charge-roller voltage control works. The value here is the base
value for the charge-roller voltage control.
ID sensor pattern [0 ~ 400 /
300
/ 1 V/step] 2001 2
Adjusts the voltage applied to the charge roller for the ID sensor pattern (as part of
charge-roller voltage correction). The charge-roller voltage is obtained by adding
SP2-001-002 to the value of SP2-001-001.
2101* Erase Margin Adjustment Adjusts the width of the erased area (☛ 3.14).
2101 1 Leading edge [0.0 ~ 9.0 /
3.0
/ 0.1 mm/step]
Specification: 2 ± 1.5 mm
Trailing [0.0 ~ 9.0 / 4
.0
/ 0.1 mm/step]
Specification: 2 +2.5/–1.5 mm
2101 2
The rear trailing edge is this value plus 1.2 mm.
Left side [0.0 ~ 9.0 /
2.0
/ 0.1 mm/step]
Specification: 2 ± 1.5 mm
2101 3
The rear left edge is this value plus 0.3 mm.
Right side [0.0 ~ 9.0 /
2.0
/ 0.1 mm/step]
Specification: 2 +2.5/–1.5 mm
2101 4
The rear right edge is this value plus 0.3 mm.
2201* Development Bias Adjustment
Printing [–1500 ~ –200 /
–650
/ 1 V/step] 2201 1
Adjusts the voltage applied to the development roller for printing. Image density
becomes higher when you specify a smaller value (a greater absolute value). Image
density becomes lower when you specify a greater value (a smaller absolute value).
ID sensor pattern [–2 = LL (220 V) / -1 = L (260 V) /
0
= N (300 V) / 1 =
H (340 V) / 2 = HH (380 V)]
2201 2
Adjusts the voltage applied to the development roller for the ID sensor pattern. The
voltage applied is obtained by adding SP2-201-002 to SP2-201-1. The setting
affects ID sensor pattern density, which in turn affects the toner supply.
2213* Outputs after Near End
2213 1 [
0
= 50 pages / 1 = 20 pages]
Sets the number of copy/print/fax pages that can be made after toner near-end has
been detected. Reduce the number of pages if the user normally makes copies with
a high image ratio.
2214
Developer Initialization
2214 1
Initializes the TD sensor toner supply target voltage and the TD sensor gain value.
Execute this SP replacing the developer or the TD sensor.
