Printing
[–1500 to –200 / –650 / 1 V/step]
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)]
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.

ID Error Analysis (
"ID Sensor Error Analysis (SP2-221)")
2221 1 Vsg Displays the Vsg value.
2221 2 Vsp Displays the Vsp value.
2221 3 PWM Displays the PWM value.
2221 4 Vsdp Displays the Vsdp value.
