2201* Dv Bias Adj
Printing
[–1500 to –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 NE
2213 1
[ 0 = 50 pages / 1 = 20 sheets]
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 Develpr Initialize
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.
