Function/[Setting]
Adjusts the voltage applied to the charge roller when
printing.
[–2100 ~ –1500 / –1700 / 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.
Adjusts the voltage applied to the charge roller when
generating the Vsdp ID sensor pattern (as part of charge
roller voltage correction).
[0 ~ 400 / 300 / 1 V/step]
The actual charge-roller voltage is obtained by adding this
value to the value of SP2-001-1.
Adjusts the leading edge erase margin.
[0.0 ~ 9.0 / 2.0 / 0.1 mm/step] IAJ
±
Specification: 2 1.5 mm
(Have Engine Firmware 1.30 or Newer)
Adjusts the trailing edge erase margin. The rear trailing
edge is this value plus 1.2 mm.
[0.0 ~ 9.0 / 4.0 / 0.1 mm/step] IAJ
Specification: 2 +2.5/–1.5 mm
(Have Engine Firmware 1.30 or Newer)
Adjusts the left edge erase margin. The rear left edge is
this value plus 0.3 mm.
[0.0 ~ 9.0 / 2.0 / 0.1 mm/step] IAJ
±
Specification: 2 1.5 mm
Adjusts the right edge erase margin. The rear right edge is
this value plus 0.3 mm.
[0.0 ~ 9.0 / 2.0 / 0.1 mm/step] IAJ
Specification: 2 +2.5/–1.5 mm
Adjusts the voltage applied to the development roller
when printing.
[–1500 ~ –200 / –650 / 1 V/step]
This can be adjusted as a temporary measure if faint
copies are being produced due to an aging drum.
Adjusts the voltage applied to the development roller
when generating the ID sensor pattern.
[–2 = LL (220 V) / -1 = L (260 V) / 0 = N (300 V) / 1 = H
(340 V) / 2 = HH (380 V)]
The actual voltage applied is this setting plus the value of
SP2-201-1. The setting affects ID sensor pattern density,
which in turn affects the toner supply.
