Fusing Nip Band Check109
1 Checks the fusing nip band.

Mode Number/Name Function/[Setting]
001* Charge Bias Adjustment
1 Image area Adjusts the voltage applied to the charge roller when
printing.
[–1800 ~ –1500 / –1650 / 1 V/step]
The actually 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.
2 ID sensor pattern Adjusts the voltage applied to the charge roller when
generating the ID sensor pattern.
[0 ~ 400 / 200 / 1 V/step]
The actual charge-roller voltage is obtained by adding this
value to the value of SP2-001-1.
3 Manual
Use this feature to adjust the voltage to the image area
when diagnosing a problem.
[-1900 ~ 0 / 0 / 1 V/step]
• The value is applied as an offset to the value set by
SP2-001-001.
• This setting is lost at power-off.
005 Charge Bias Correction
1 Vsdp min. Sets lower limit for application of charge-bias correction.
[0 ~ 100 / 90 / 1%/step]
Correction is applied if Vsdp/Vsg is less than this value.
2 Vsdp max. Sets upper limit for application of charge-bias correction.
[0 ~ 100 / 95 / 1%/step]
Correction is applied if Vsdp/Vsg is greater than this
value.
3 Correction step
Sets the correction step (the amount of voltage added or
subtracted for each correction).
[0 ~ 200 / 50 / 1V/step]
