ID sensor pattern
Adjusts the voltage applied to the charge roller for the ID sensor pattern (as part of charge-
2001 2
roller voltage correction). The charge-roller voltage is obtained by adding SP2-001-002
to the value of SP2-001-001.

2101 1 Leading Edge
Trailing Edge
2101 2
The rear trailing edge is this value plus 1.2 mm.
Left side
2101 3
The rear left edge is this value plus 0.3 mm.
Right side
2101 4
The rear right edge is this value plus 0.3 mm.
2201* Dv Bias Adj
Printing
Adjusts the voltage applied to the development roller for printing. Image density becomes
2201 1
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
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.
