ID sensor pattern
Adjusts the voltage applied to the charge roller for the ID sensor pattern (as part of
2001 2
charge-roller voltage correction). Setting the same value as "SP2-201-002" is
preferable.
Temporally Input
Inputs the voltage value. Too small value may cause the charge roller tainted. Too large
2001 3
value may cause attaching carrier particles in developer, on a printed paper. The value
from – 1800 V to 1600 V is preferable.
2005* Charge Bias Correction

Charge Roller Bias Correction (Step)
2005 3
Sets correction value by one step for bias adjustment to meet SP2001-001 setting value.
