Setting (Copying)
(Printing)
Adjusts the voltage applied to the charge roller when printing. The actually
001
applied voltage changes automatically as charge roller voltage correction is
carried out. The value you set here becomes the base value on which this
correction is carried out.
ID Sensor Pattern
Adjusts the voltage applied to the charge roller when generating the Vsdp ID
002
sensor pattern (as part of charge roller voltage correction). The actual
chargeroller voltage is obtained by adding this value to the value of SP 2001 1.
Temporally Input
(D158/D159)
003
Enter the voltage values directly. Background dirt occurs when the value is too
low, and easy to adhere the toner careers when it is too high. Between 1600V
to -1800V recommended.
