SP2-XXX (Drum)
2001* Charge Roller Bias Adjustment
2001 1 Printing
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.
2001 2 ID sensor pattern
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
2101 1 Leading edge
2101 2 Trailing
The rear trailing edge is this value plus 1.2 mm.
2101 3 Left side
The rear left edge is this value plus 0.3 mm.
2101 4 Right side
The rear right edge is this value plus 0.3 mm.
2201* Development Bias Adjustment
2201 1 Printing
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).
2201 2 ID sensor pattern
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.
