Function
Adjusts the duplex inverter motor speed
during forward rotation at high speed.
Use this SP when paper often jams at the
duplex entrance area. Do not use in the field
unless directed by service centre staff.
Adjusts the duplex inverter motor speed
during forward rotation at low speed.
Use this SP when paper often jams at the
duplex inverter area. Do not use in the field
unless directed by service centre staff.
Adjusts the duplex inverter motor speed
during forward rotation at high speed.
Use this SP when paper often jams at the
duplex inverter area. Do not use in the field
unless directed by service centre staff.
Adjusts the duplex transport motor speed
during forward rotation at low speed.
Use this SP when paper often jams at the
duplex entrance area when feeding paper
from the duplex unit to the registration area.
Do not use in the field unless directed by
service centre staff.
Adjusts the duplex transport motor speed
during forward rotation at high speed.
Use this SP when paper often jams at the
duplex entrance area when feeding paper

Do not use in the field unless directed by
service centre staff.
Selects whether fusing idling is done or not
when the machine returns to stand-by mode
from low power mode level 2.
If this is at "1" and the fusing temperature in
low power mode level 2 is 70°C ~ 90°C,
fusing idling is done. See "Fusing
Temperature Control" for more details.
Adjusts the voltage applied to the charge
roller during printing.
This value will be changed automatically
when the charge roller bias correction is
performed.
Note that if this value is changed, the charge
roller voltage will be corrected based on the
new voltage.
Adjusts the voltage applied to the charge
roller when making the Vsdp ID sensor
pattern (for charge roller bias correction).
The actual charge roller voltage is this value
plus the value of SP2-001-1.
